\section{Introduction}
|
||||||
organizing your client-side Javascript into a classic
|
|
||||||
Model-View-Controller paradigm while trying (and to some extent,
|
|
||||||
succeeding) in trying to burden you, the user, with as little
|
|
||||||
additional learning as possible. I consider this a good thing; the
|
|
||||||
overhead of learning a library and its accompaning DSL represent
|
|
||||||
additional cognitive loads that developers can better use elsewhere.
|
|
||||||
Keeping as much as possible within familiar paradigms is not just
|
|
||||||
useful, it's necessary as our programs get bigger.
|
|
||||||
|
|
||||||
The tutorial for Backbone is woefully lacking in specifics, and the
|
I've been playing with
|
||||||
example program, Todo, doesn't really have much chops in teaching you
|
\nwanchorto{http://documentcloud.github.com/backbone/}{Backbone.js}, a
|
||||||
the ins and outs of Backbone, especially not its new Controller and
|
small but nifty Javascript library that provides a small
|
||||||
History modules. But in the announcement for Backbone.Controller,
|
Model-View-Controller framework where Models can generate events that
|
||||||
Jeremy Ashkenas hid a clue: There's another library, Sammy.js, that
|
trigger View changes, and vice versa, along with a Collections models
|
||||||
does something similar, and they do have a tutorial called \nwanchorto{http://code.quirkey.com/sammy/tutorials/json_store_part1.html}{The JsonStore}.
|
so groups of models can cause view-level events, and a Sync library
|
||||||
|
that provides a basic REST architecture for propagating client-made
|
||||||
|
changes back to the server.
|
||||||
|

A note: this article was written with the
|
||||||

|
||||||
|

|
||||||
|
\nwanchorto{http://www.cs.tufts.edu/~nr/noweb/}{Noweb}. Where you see
|
||||||
|
something that looks like \<\<this\>\>, it's a placeholder for code
|
||||||
|
described elsewhere in the document. Placeholders with an equal sign
|
||||||
|
at the end of them indicate the place where that code is defined. The
|
||||||
|
link (U->) indicates that the code you're seeing is used later in the
|
||||||
|
document, and (<-U) indicates it was used earlier but is being defined
|
||||||
|
here.
|
||||||
|
|
||||||
|
\subsection{Revision}
|
||||||
|
|
||||||
|
This is version 1.2 of \textit{The Backbone Store}. It includes
|
||||||
|
changes to the store based upon a better understanding of what
|
||||||
|
Backbone.js can do. This version uses jQuery 1.5 and Backbone 0.3.3.
|
||||||
|
|
||||||
|
\subsection{The Store}
|
||||||
|
|
||||||
|
The store has three features: A list of products, a product detail
|
||||||
|
page, and a ``shopping cart'' that does nothing but tally up the
|
||||||
|
number of products total that you might wish to order. The main
|
||||||
|
viewport flips between a list of products and a product detail; the
|
||||||
|
shopping cart quantity tally is always visible.
|
||||||
|
|
||||||
|
Let's start by showing you the HTML that we're going to be
|
||||||
|
exploiting. As you can see, the shopping cart's primary display is
|
||||||
|
already present, with zero items shoving. DOM ID ``main'' is empty.
|
||||||
|
We'll fill it with templated data later.

|
||||||
|
|
||||||
There are two views, the index and the item. So, using
|
\section{The Program}
|
||||||
[[Backbone.Controller]], we're going to route the following:
|
|
||||||
|
|
||||||
<<routes>>=
|
And here's the skeleton of the program we're going to be writing:
|
||||||
routes: {
|
|
||||||
"": "index",
|
|
||||||
"item/:id": "item",
|
|
||||||
},
|
|
||||||
@
|
|
||||||
|
|
||||||
Unlike Sammy, Backbone mostly only routes GET commands. Routes are to
|
|
||||||
routes to views; everything else happens more or less under the
|
|
||||||
covers.
|
|
||||||
|
|
||||||
As Backbone is running, the [[Backbone.History]] module is listening to
|
|
||||||
the hash object, waiting for it to change so that it can trigger a
|
|
||||||
``route'' event, in which case the function named as the value in the
|
|
||||||
route is called.
|
|
||||||
|
|
||||||
There are a few things I want to track: the index view, the individual
|
|
||||||
product views, and the shopping cart.
|
|
||||||
|
|
||||||
<<application variables>>=
|
|
||||||
_index: null,
|
|
||||||
_products: null,
|
|
||||||
_cart :null,
|
|
||||||
@
|
|
||||||
|
|
||||||
Using backbone, I have a list of products. So, I should declare
|
|
||||||
those. The basic product is just a model, with nothing to show for
|
|
||||||
it; the list of products is a [[Backbone.Collection]], with one feature,
|
|
||||||
the [[comparator]], which sorts the albums in order by album title.
|
|
||||||
|
|
||||||
<<product models>>=
|
|
||||||
var Product = Backbone.Model.extend({});
|
|
||||||
|
|
||||||
var ProductCollection = Backbone.Collection.extend({
|
|
||||||
model: Product,
|
|
||||||
comparator: function(item) {
|
|
||||||
return item.get('title');
|
|
||||||
}
|
|
||||||
});
|
|
||||||
@
|
|
||||||
|
|
||||||
That's not very exciting. Let's show this list, with a View. Let's
|
|
||||||
call it IndexView:
|
|
||||||
|
|
||||||
<<index view>>=
|
|
||||||
var IndexView = Backbone.View.extend({
|
|
||||||
el: $('#main'),
|
|
||||||
indexTemplate: $("#indexTmpl").template(),
|
|
||||||
|
|
||||||
render: function() {
|
|
||||||
var sg = this;
|
|
||||||
this.el.fadeOut('fast', function() {
|
|
||||||
sg.el.empty();
|
|
||||||
$.tmpl(sg.indexTemplate, sg.model.toArray()).appendTo(sg.el);
|
|
||||||
sg.el.fadeIn('fast');
|
|
||||||
});
|
|
||||||
return this;
|
|
||||||
}
|
|
||||||
|
|
||||||
});
|
|
||||||
@
|
|
||||||
|
|
||||||
This code defines a [[Backbone.View]] object, in which the parent element
|
|
||||||
is \#main, the render function fades out the existing elements in that
|
|
||||||
position and replaces them with the contents of a rendered jQuery
|
|
||||||
template, and then fades the element back in.
|
|
||||||
|
|
||||||
The index template looks like this:
|
|
||||||
|
|
||||||
<<index template>>=
|
|
||||||
<script id="indexTmpl" type="text/x-jquery-tmpl">
|
|
||||||
<div class="item">
|
|
||||||
<div class="item-image">
|
|
||||||
<a href="#item/${cid}"><img src="${attributes.image}" alt="${attributes.title}" /></a>
|
|
||||||
</div>
|
|
||||||
<div class="item-artist">${attributes.artist}</div>
|
|
||||||
<div class="item-title">${attributes.title}</div>
|
|
||||||
<div class="item-price">$${attributes.price}</div>
|
|
||||||
</div>
|
|
||||||
</script>
|
|
||||||
@
|
|
||||||
|
|
||||||
There's some
|
|
||||||
\nwanchorto{http://en.wikipedia.org/wiki/Law_of_Demeter}{Demeter violations}
|
|
||||||
going on here, in that I have to know about the [[attributes]] of a
|
|
||||||
Backbone model, something that's normally hidden within the class.
|
|
||||||
But this is good enough for our purposes. The above is a jQuery
|
|
||||||
template, and the [[\$\{\}]] syntax is what's used to dereference
|
|
||||||
variables within a template.
|
|
||||||
|
|
||||||
(As an aside, I think that the [[set]] and [[get]] methods of
|
|
||||||
[[Backbone.Model]] are a poor access mechanism. I understand why they're
|
|
||||||
there, and I can only hope that someday
|
|
||||||
\nwanchorto{http://ejohn.org/blog/javascript-getters-and-setters/}{Javascript
|
|
||||||
Getter and Setters} become so well-established as to make [[set]]
|
|
||||||
and [[get]] irrelevant.)
|
|
||||||
|
|
||||||
Now, we can render the index view:
|
|
||||||
|
|
||||||
<<index render call>>=
|
|
||||||
index: function() {
|
|
||||||
this._index.render();
|
|
||||||
},
|
|
||||||
@
|
|
||||||
|
|
||||||
At this point, well, we need an application. A controller. And we
|
|
||||||
need to initialize it, and call it. Here's what it looks like (some
|
|
||||||
of this, you've already seen):
|
|
||||||
|
|
||||||
<<workspace>>=
|
|
||||||
var Workspace = Backbone.Controller.extend({
|
|
||||||
<<application variables>>
|
|
||||||
|
|
||||||
<<routes>>
|
|
||||||
|
|
||||||
<<initialization>>
|
|
||||||
|
|
||||||
<<index render call>>
|
|
||||||
|
|
||||||
<<product render call>>
|
|
||||||
});
|
|
||||||
|
|
||||||
workspace = new Workspace();
|
|
||||||
Backbone.history.start();
|
|
||||||
@
|
|
||||||
|
|
||||||
There are two things left in our workspace, that we haven't defined.
|
|
||||||
The intialization, and the product render.
|
|
||||||
|
|
||||||
Initialization consists of getting our product list, creating a
|
|
||||||
shopping cart to hold ``desired'' products (and in quantity!), and
|
|
||||||
creating the index view. (Product views, we'll discuss in a moment).
|
|
||||||
|
|
||||||
<<initialization>>=
|
|
||||||
initialize: function() {
|
|
||||||
var ws = this;
|
|
||||||
if (this._index === null) {
|
|
||||||
$.ajax({
|
|
||||||
url: 'data/items.json',
|
|
||||||
dataType: 'json',
|
|
||||||
data: {},
|
|
||||||
success: function(data) {
|
|
||||||
ws._cart = new Cart();
|
|
||||||
new CartView({model: ws._cart});
|
|
||||||
ws._products = new ProductCollection(data);
|
|
||||||
ws._index = new IndexView({model: ws._products});
|
|
||||||
Backbone.history.loadUrl();
|
|
||||||
}
|
|
||||||
});
|
|
||||||
return this;
|
|
||||||
}
|
|
||||||
return this;
|
|
||||||
},
|
|
||||||
@
|
|
||||||
|
|
||||||
We haven't defined the Cart yet, but that's all right. We'll get to
|
|
||||||
it.) But here you see a lot of what's already existent being used: we
|
|
||||||
get a ProductCollection, and an IndexView.
|
|
||||||
|
|
||||||
That last line is curious. It's an instruction to Backbone to look at
|
|
||||||
the URL; if the user navigated to something other than the home page,
|
|
||||||
it's to use the routes defined to go there. Users can now bookmark
|
|
||||||
places in your site other than the home page. Yes, the bookmark will
|
|
||||||
be funny and have at least one
|
|
||||||
\nwanchorto{http://en.wiktionary.org/wiki/octothorpe}{octothorpe} in it, but
|
|
||||||
it will work.
|
|
||||||
|
|
||||||
Let's deal with the shopping cart:
|
|
||||||
|
|
||||||
<<shopping cart models>>=
|
|
||||||
var CartItem = Backbone.Model.extend({
|
|
||||||
update: function(amount) {
|
|
||||||
this.set({'quantity': this.get('quantity') + amount});
|
|
||||||
}
|
|
||||||
});
|
|
||||||
|
|
||||||
|
|
||||||
var Cart = Backbone.Collection.extend({
|
|
||||||
model: CartItem,
|
|
||||||
getByPid: function(pid) {
|
|
||||||
return this.detect(function(obj) { return (obj.get('product').cid == pid); });
|
|
||||||
},
|
|
||||||
});
|
|
||||||
@
|
|
||||||
|
|
||||||
A little rocket science here: A [[Cart]] contains [[CartItems]]. Each
|
|
||||||
``item'' represents a quantity of a [[Product]]. (I know, that always
|
|
||||||
struck me as odd, but that's how most online stores do it.)
|
|
||||||
[[CartItem]] has an update method that allows you to add more (but not
|
|
||||||
remove any-- hey, the Sammy store wasn't any smarter, and this is For
|
|
||||||
Demonstration Purposes Only), and we use the [[set]] method to make
|
|
||||||
sure that a ``change'' event is triggered.
|
|
||||||
|
|
||||||
The [[Cart]], in turn, has a method, getByPid (``Product ID''), which
|
|
||||||
is meant to assist other objects in finding the [[CartItem]]
|
|
||||||
associated with a specific product. Here, I'm just using the Backbone
|
|
||||||
default client id.
|
|
||||||
|
|
||||||
The cart is represented by a little tag in the upper right-hand corner
|
|
||||||
of the view; it never goes away, and its count is always the total
|
|
||||||
number of [[Products]] (not [[CartItem]]s) ordered. So the
|
|
||||||
[[CartView]] needs to update whenever a [[CartItem]] is added or
|
|
||||||
updated. And we want a nifty little animation to go with it:
|
|
||||||
|
|
||||||
<<shopping cart view>>=
|
|
||||||
var CartView = Backbone.View.extend({
|
|
||||||
el: $('.cart-info'),
|
|
||||||
|
|
||||||
initialize: function() {
|
|
||||||
this.model.bind('change', _.bind(this.render, this));
|
|
||||||
},
|
|
||||||
|
|
||||||
render: function() {
|
|
||||||
var sum = this.model.reduce(function(m, n) { return m + n.get('quantity'); }, 0);
|
|
||||||
this.el
|
|
||||||
.find('.cart-items').text(sum).end()
|
|
||||||
.animate({paddingTop: '30px'})
|
|
||||||
.animate({paddingTop: '10px'});
|
|
||||||
}
|
|
||||||
});
|
|
||||||
@
|
|
||||||
|
|
||||||
A couple of things here: the render is rebound to [[this]] to make
|
|
||||||
sure it renders in the context of the view. I found that that was not
|
|
||||||
always happening. Note the use of [[reduce]], a nifty method from
|
|
||||||
[[underscore.js]] that allows you to build a result out an array using
|
|
||||||
an anonymous function. This reduce, obviously, sums up the total
|
|
||||||
quantity of items in the cart. Also, jQuery enthusiasts could learn
|
|
||||||
(I certainly did!) from the [[.find()]] and [[.end()]] methods, which
|
|
||||||
push a child object onto the stack to be animated, and then pop it off
|
|
||||||
after the operation has been applied.
|
|
||||||
|
|
||||||
The biggest thing left is the [[ProductView]]. It's skeleton looks
|
|
||||||
like this:
|
|
||||||
|
|
||||||
<<product view>>=
|
|
||||||
var ProductView = Backbone.View.extend({
|
|
||||||
el: $('#main'),
|
|
||||||
itemTemplate: $("#itemTmpl").template(),
|
|
||||||
|
|
||||||
<<product events>>
|
|
||||||
|
|
||||||
initialize: function(options) {
|
|
||||||
this.cart = options.cart;
|
|
||||||
},
|
|
||||||
|
|
||||||
<<update product>>
|
|
||||||
|
|
||||||
<<render product>>
|
|
||||||
});
|
|
||||||
|
|
||||||
@
|
|
||||||
|
|
||||||
First, we find the element we're going to work with, and the template.
|
|
||||||
I expect the ProductView to be where we'll add items to the cart, so
|
|
||||||
the initializer here expects to have a handle on the cart.
|
|
||||||
|
|
||||||
And the template:
|
|
||||||
|
|
||||||
<<product template>>=
|
|
||||||
<script id="itemTmpl" type="text/x-jquery-tmpl">
|
|
||||||
<div class="item-detail">
|
|
||||||
<div class="item-image"><img src="${attributes.large_image}" alt="${attributes.title}" /></div>
|
|
||||||
<div class="item-info">
|
|
||||||
<div class="item-artist">${attributes.artist}</div>
|
|
||||||
<div class="item-title">${attributes.title}</div>
|
|
||||||
<div class="item-price">$${attributes.price}</div>
|
|
||||||
<div class="item-form">
|
|
||||||
<form action="#/cart" method="post">
|
|
||||||
<input type="hidden" name="item_id" value="${cid}" />
|
|
||||||
<p>
|
|
||||||
<label>Quantity:</label>
|
|
||||||
<input type="text" size="2" name="quantity" value="1" class="uqf" />
|
|
||||||
</p>
|
|
||||||
<p><input type="submit" value="Add to Cart" class="uq" /></p>
|
|
||||||
</form>
|
|
||||||
</div>
|
|
||||||
<div class="item-link"><a href="${attributes.url}">Buy this item on Amazon</a></div>
|
|
||||||
<div class="back-link"><a href="#">« Back to Items</a></div>
|
|
||||||
</div>
|
|
||||||
</div>
|
|
||||||
</script>
|
|
||||||
@
|
|
||||||
|
|
||||||
One extra item: note the octothorpe used as the target link for
|
|
||||||
``Home''. I kept thinking an empty link or just ``/'' would be
|
|
||||||
appropriate, but no, it's an octothorpe.
|
|
||||||
|
|
||||||
Rendering the product is not difficult:
|
|
||||||
|
|
||||||
<<render product>>=
|
|
||||||
render: function() {
|
|
||||||
var sg = this;
|
|
||||||
this.el.fadeOut('fast', function() {
|
|
||||||
sg.el.empty();
|
|
||||||
$.tmpl(sg.itemTemplate, sg.model).appendTo(sg.el);
|
|
||||||
sg.el.fadeIn('fast');
|
|
||||||
});
|
|
||||||
return this;
|
|
||||||
}
|
|
||||||
@
|
|
||||||
|
|
||||||
That looks familiar.
|
|
||||||
|
|
||||||
Updating the product, however, is a whole 'nother story. Note that
|
|
||||||
each product has a form associated with it. We need to intercept any
|
|
||||||
form update events and manipulate our shopping cart. We have two
|
|
||||||
objects that can do that: the input field, and the submit button. I
|
|
||||||
need to intercept those events:
|
|
||||||
|
|
||||||
<<product events>>=
|
|
||||||
events: {
|
|
||||||
"keypress .uqf" : "updateOnEnter",
|
|
||||||
"click .uq" : "update",
|
|
||||||
},
|
|
||||||
@
|
|
||||||
|
|
||||||
Backbone uses a curious definition of an event with an ``event
|
|
||||||
selector'', followed by a target method of the View class. Backbone
|
|
||||||
is also limited about what events can be used here, as the following
|
|
||||||
events cannot be wrapped by jQuery's delegate method and do not work:
|
|
||||||
``focus'', ``blur'', ``change'', ``submit'', and ``reset''.
|
|
||||||
|
|
||||||
The update then becomes straightforward. We're in a view for a
|
|
||||||
specific product; we must see if the customer has a [[CartItem]] for
|
|
||||||
that product in the [[Cart]], and add or update it as needed. Like
|
|
||||||
so:
|
|
||||||
|
|
||||||
<<update product>>=
|
|
||||||
update: function(e) {
|
|
||||||
e.preventDefault();
|
|
||||||
var cart_item = this.cart.getByPid(this.model.cid);
|
|
||||||
if (_.isUndefined(cart_item)) {
|
|
||||||
cart_item = new CartItem({product: this.model, quantity: 0});
|
|
||||||
this.cart.add(cart_item, {silent: true});
|
|
||||||
}
|
|
||||||
cart_item.update(parseInt($('.uqf').val()));
|
|
||||||
},
|
|
||||||
|
|
||||||
updateOnEnter: function(e) {
|
|
||||||
if (e.keyCode == 13) {
|
|
||||||
return this.update(e);
|
|
||||||
}
|
|
||||||
},
|
|
||||||
@
|
|
||||||
|
|
||||||
We [[preventDefault]] to keep the traditional meaning of the submit
|
|
||||||
button from triggering. When the [[CartItem]] is updated, it triggers
|
|
||||||
a ``change'' event, and the [[CartView]] will update itself
|
|
||||||
automatically. I added the ``silent'' option to keep the ``change''
|
|
||||||
event from triggering twice when adding a new [[CartItem]] to the
|
|
||||||
[[Cart]].
|
|
||||||
|
|
||||||
And now I'm down to one last thing. I haven't defined that product
|
|
||||||
render call in the application controller. The one thing I don't want
|
|
||||||
to do is have [[ProductViews]] for every product, if I don't need
|
|
||||||
them. So I want to build them as-needed, but keep them, and associate
|
|
||||||
them with the local [[Product]], so they can be recalled whenever we
|
|
||||||
want. The underscore function [[isUndefined]] is excellent for this.
|
|
||||||
|
|
||||||
<<product render call>>=
|
|
||||||
item: function(id) {
|
|
||||||
if (_.isUndefined(this._products.getByCid(id)._view)) {
|
|
||||||
this._products.getByCid(id)._view = new ProductView({model: this._products.getByCid(id),
|
|
||||||
cart: this._cart});
|
|
||||||
}
|
|
||||||
this._products.getByCid(id)._view.render();
|
|
||||||
}
|
|
||||||
@
|
|
||||||
|
|
||||||
And now my store looks like
|
|
||||||
|
|
||||||
<<store.js>>=

|

\section{Models and Collections for the Store}
|
||||||
|
|
||||||
|
Products are basically what we're selling. In Backbone, a product
|
||||||
|
maps to a Backbone Model. Backbone's Model class provides a full
|
||||||
|
suite of methods for setting and deleting attributes.
|
||||||
|
|
||||||
|
One of things I've found useful is to expose the CID (an internal and
|
||||||
|
locally unique ``client ID'' generated by Backbone) and use it to
|
||||||
|
decorate DOM id's and classes. So, here, I override the Models's
|
||||||
|
[[toJSON()]] and add the CID to the representation. In production,
|
||||||
|
I've typically created a parent class for all of my classes, overriden
|
||||||
|
[[toJSON()]], and extended that instead.
|
||||||
|
|
||||||
|
<<product models>>=
|
||||||
|
var Product = Backbone.Model.extend({
|
||||||
|
toJSON: function() {
|
||||||
|
return _.extend(_.clone(this.attributes), {cid: this.cid})
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
A store has a lot of products, so we use a Backbone Collection to keep
|
||||||
|
track of them. A Collection always has a Model object associated with
|
||||||
|
it; if you attempt to add an object to the Collection that is not an
|
||||||
|
instance of [[Backbone.Model]], the Collection will attempt to coerce
|
||||||
|
that object into it [[model]] type.
|
||||||
|
|
||||||
|
Both Models and Collections have a [[toJSON()]] method. The Model
|
||||||
|
creates a JSON representation of its attributes, and the collection
|
||||||
|
creates a JSON representation of an array, calling [[Model.toJSON()]]
|
||||||
|
for each model in contains.
|
||||||
|
|
||||||
|
|
||||||
|
The other novel thing here is the comparator; Backbone uses it define
|
||||||
|
the default ordering for the collection. If not defined, calling
|
||||||
|
[[sort()]] on the collection raises an exception.
|
||||||
|
|
||||||
|
<<product models>>=
|
||||||
|
var ProductCollection = Backbone.Collection.extend({
|
||||||
|
model: Product,
|
||||||
|
|
||||||
|
comparator: function(item) {
|
||||||
|
return item.get('title');
|
||||||
|
}
|
||||||
|
});
|
||||||
|
@
|
||||||
|
|
||||||
|
Shopping carts are a bit strange. The typical cart has items: each
|
||||||
|
item represents one product and the quantity the user wants to buy.
|
||||||
|
So a cart may have two items, but the user may be buying five things:
|
||||||
|
one of the first item, and four of the second, and so forth.
|
||||||
|
|
||||||
|
For our (simple) purpose, I'm just going to have an item that you can
|
||||||
|
add amounts to, that get stored as a 'quantity'.
|
||||||
|
|
||||||
|
<<shopping cart models>>=
|
||||||
|
var CartItem = Backbone.Model.extend({
|
||||||
|
update: function(amount) {
|
||||||
|
this.set({'quantity': this.get('quantity') + amount});
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
The other feature is that, for the collection, I will want to find the
|
||||||
|
CartItem not by its ID, but by the ID of the product it contains. So
|
||||||
|
I have added the method [[getByProductId]].
|
||||||
|
|
||||||
|
<<shopping cart models>>=
|
||||||
|
var Cart = Backbone.Collection.extend({
|
||||||
|
model: CartItem,
|
||||||
|
getByProductId: function(pid) {
|
||||||
|
return this.detect(function(obj) { return (obj.get('product').cid == pid); });
|
||||||
|
},
|
||||||
|
});
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
\section{Views}
|
||||||
|
|
||||||
|
Backbone Views are simple policy objects. They often have a root
|
||||||
|
element, the contents of which they manipulate, a model or collection
|
||||||
|
they represent within that root element, events that may occur within
|
||||||
|
that root element that they monitor and consequently act on. Views
|
||||||
|
are not rigid; it's just Javascript and the DOM, and you can hook
|
||||||
|
external events as needed. (This can be useful, for example, when
|
||||||
|
doing drag-and-drop with jQueryUI to highlight valid drop zones.)
|
||||||
|
More importantly, it is sensitive to events \textit{within its model
|
||||||
|
or collection}, and can respond to changes automatically, without
|
||||||
|
having to manually invoke the view.
|
||||||
|
|
||||||
|
There are three views here: the CartView, the ProductListView, and a
|
||||||
|
single ProductView.
|
||||||
|
|
||||||
|
The [[CartView]] lives in the upper-right-hand corner of our screen,
|
||||||
|
and just shows the quantity of items in our shopping cart. It has a
|
||||||
|
default [[el]], where it will draw its quantity. This view
|
||||||
|
illustrates the binding to its collection: whenever the collection is
|
||||||
|
updated in some way, the [[CartView]] automagically updates itself.
|
||||||
|
The programmer is now relieved of any responsibility of remembering to
|
||||||
|
update the view, which is a huge win. The [[\_.bind()]] method
|
||||||
|
associates the [[render]] with the instance of the [[CartView]].
|
||||||
|
|
||||||
|
The [[render()]] method is the conventional name for rendering the
|
||||||
|
elements. Nothing in Backbone calls [[render()]] directly; it's up to
|
||||||
|
the developer to decide how and when an object should should be
|
||||||
|
rendered.
|
||||||
|
|
||||||
|
This also illustrates the use of jQuery animations in Backbone.
|
||||||
|
|
||||||
|
<<shopping cart view>>=
|
||||||
|
var CartView = Backbone.View.extend({
|
||||||
|
el: $('.cart-info'),
|
||||||
|
|
||||||
|
initialize: function() {
|
||||||
|
this.collection.bind('change', _.bind(this.render, this));
|
||||||
|
},
|
||||||
|
|
||||||
|
render: function() {
|
||||||
|
var sum = this.collection.reduce(function(m, n) { return m + n.get('quantity'); }, 0);
|
||||||
|
this.el
|
||||||
|
.find('.cart-items').text(sum).end()
|
||||||
|
.animate({paddingTop: '30px'})
|
||||||
|
.animate({paddingTop: '10px'});
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
@
|
||||||
|
%$
|
||||||
|
|
||||||
|
The [[ProductListView]] again has a root element, this time the
|
||||||
|
[[#main]] DIV of our HTML, into which we're going to draw a jQuery
|
||||||
|
template list of our record albums.
|
||||||
|
|
||||||
|
The only tricks here are the compilation of the jQuery template when
|
||||||
|
the View is instantiated, and the use of an enclosured (is that a
|
||||||
|
word?) [[self]] variable to provide a hard context for the [[this]]
|
||||||
|
variable within inner jQuery calls.
|
||||||
|
|
||||||
|
<<product list view>>=
|
||||||
|
var ProductListView = Backbone.View.extend({
|
||||||
|
el: $('#main'),
|
||||||
|
indexTemplate: $("#indexTmpl").template(),
|
||||||
|
|
||||||
|
render: function() {
|
||||||
|
var self = this;
|
||||||
|
this.el.fadeOut('fast', function() {
|
||||||
|
self.el.html($.tmpl(self.indexTemplate, self.model.toJSON()));
|
||||||
|
self.el.fadeIn('fast');
|
||||||
|
});
|
||||||
|
return this;
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
The view uses a jQuery template. This is a simple, repeatable
|
||||||
|
template that jQuery.Template, upon encountering an array, repeats
|
||||||
|
until the array is exhausted. Note the presence of [[\${cid}]].
|
||||||
|
|
||||||
|
<<product list template>>=
|
||||||
|
<script id="indexTmpl" type="text/x-jquery-tmpl">
|
||||||
|
<div class="item">
|
||||||
|
<div class="item-image">
|
||||||
|
<a href="#item/${cid}"><img src="${image}" alt="${title}" /></a>
|
||||||
|
</div>
|
||||||
|
<div class="item-artist">${artist}</div>
|
||||||
|
<div class="item-title">${title}</div>
|
||||||
|
<div class="item-price">$${price}</div>
|
||||||
|
</div>
|
||||||
|
</script>
|
||||||
|
@
|
||||||
|
%$
|
||||||
|
|
||||||
|
The most complicated object in our ecosystem is the product view. It
|
||||||
|
actually does something! The prefix ought to be familiar, but note
|
||||||
|
that we're again using [[#main]] as our target; we'll be replacing
|
||||||
|
these contents over and over.
|
||||||
|
|
||||||
|
<<product view>>=
|
||||||
|
var ProductView = Backbone.View.extend({
|
||||||
|
el: $('#main'),
|
||||||
|
itemTemplate: $("#itemTmpl").template(),
|
||||||
|
|
||||||
|
initialize: function(options) {
|
||||||
|
this.cart = options.cart;
|
||||||
|
return this;
|
||||||
|
},
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
We want to update the cart as needed. Remember that when we update
|
||||||
|
the cart item, the CartView will be notified automagically. Later,
|
||||||
|
I'll show how when we initialize and route to a product view, we pass
|
||||||
|
in the model associated with it. This code ought to be fairly
|
||||||
|
readable: the only specialness is that it's receiving an event, and
|
||||||
|
we're ``silencing'' the call to [[cart.add()]], which means that the
|
||||||
|
cart collection will not publish any events. There are only events
|
||||||
|
when the item has more than zero, and that gets called on
|
||||||
|
[[cart_item.update()]].
|
||||||
|
|
||||||
|
<<product view>>=
|
||||||
|
update: function(e) {
|
||||||
|
e.preventDefault();
|
||||||
|
var cart_item = this.cart.getByProductId(this.model.cid);
|
||||||
|
if (_.isUndefined(cart_item)) {
|
||||||
|
cart_item = new CartItem({product: this.model, quantity: 0});
|
||||||
|
this.cart.add(cart_item, {silent: true});
|
||||||
|
}
|
||||||
|
cart_item.update(parseInt($('.uqf').val()));
|
||||||
|
},
|
||||||
|
|
||||||
|
updateOnEnter: function(e) {
|
||||||
|
if (e.keyCode == 13) {
|
||||||
|
return this.update(e);
|
||||||
|
}
|
||||||
|
},
|
||||||
|
|
||||||
|
@
|
||||||
|
%$
|
||||||
|
|
||||||
|
These are the events in which we're interested: keypresses and clicks
|
||||||
|
on the update button and the quantity form. (Okay, ``UQ'' isn't the
|
||||||
|
best for ``update quantity''. I admit that.) Note the peculiar
|
||||||
|
syntax of ``EVENT SELECTOR'': ``methodByName'' for each event.
|
||||||
|
|
||||||
|
Backbone tells us that the only events it can track by itself are
|
||||||
|
those that jQuery's ``delegate'' understands. As of 1.5, that seems
|
||||||
|
to be just about all of them.
|
||||||
|
|
||||||
|
One thing that I was not aware of until recently: if you remove and
|
||||||
|
replace the [[el]] object during the lifespan of your view (including
|
||||||
|
in [[initialize()]]), you must then call [[delegateEvents()]] again on
|
||||||
|
the new object for these events to work.
|
||||||
|
|
||||||
|
<<product view>>=
|
||||||
|
events: {
|
||||||
|
"keypress .uqf" : "updateOnEnter",
|
||||||
|
"click .uq" : "update",
|
||||||
|
},
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
And finally the render. There is no rocket science here. You've seen
|
||||||
|
this before.
|
||||||
|
|
||||||
|
%'
|
||||||
|
<<product view>>=
|
||||||
|
render: function() {
|
||||||
|
var self = this;
|
||||||
|
this.el.fadeOut('fast', function() {
|
||||||
|
self.el.html($.tmpl(self.itemTemplate, self.model.toJSON()));
|
||||||
|
self.el.fadeIn('fast');
|
||||||
|
});
|
||||||
|
return this;
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
The template for a ProductView is straightforward. It contains the
|
||||||
|
form with the [[uq]] objects, the actions of which we intercept and
|
||||||
|
operate on internally. Backbone does this automatically using
|
||||||
|
jQuery's [[delegate]] method.
|
||||||

\section{The Router}
|
||||||
|
|
||||||
|
The router is a fairly straightforward component. It's purpose is to
|
||||||
|
pay attention to the ``\#hash'' portion of your URL and, when it
|
||||||
|
changes, do something. Anything, really. [[Backbone.History]] is the
|
||||||
|
event listener for the hash, so it has to be activated after the
|
||||||
|
application. In many ways, a Backbone ``Controller'' is just a big
|
||||||
|
View with authority over the entire Viewport.
|
||||||
|
|
||||||
|
To begin with, I'm going to keep track of the ``three'' views I care
|
||||||
|
about: the CartView, the ProductListView, and the ProductView. I'm
|
||||||
|
going to cheat by attaching the ProductViews to their individual
|
||||||
|
products, and invoke that view as necessary.
|
||||||
|
|
||||||
|
<<application>>=
|
||||||
|
var BackboneStore = Backbone.Controller.extend({
|
||||||
|
_index: null,
|
||||||
|
_products: null,
|
||||||
|
_cart :null,
|
||||||
|
@
|
||||||
|
%$
|
||||||
|
|
||||||
|
There are only two routes: home, and item:
|
||||||
|
|
||||||
|
<<application>>=
|
||||||
|
routes: {
|
||||||
|
"": "index",
|
||||||
|
"item/:id": "item",
|
||||||
|
},
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
Here's where things get interesting. There are two schools of thought
|
||||||
|
over the Controller; one, that the Controller ought to be able to get
|
||||||
|
all the data it needs, and two, that the Controller ought to begin
|
||||||
|
with enough data to do the job sensibly. I fall into the second camp.
|
||||||
|
I'm going to pass in to the [[initialize()]] method an array of
|
||||||
|
objects representing all the products in the system.
|
||||||
|
|
||||||
|
<<application>>=
|
||||||
|
initialize: function(data) {
|
||||||
|
this._cart = new Cart();
|
||||||
|
new CartView({collection: this._cart});
|
||||||
|
this._products = new ProductCollection(data);
|
||||||
|
this._index = new ProductListView({model: this._products});
|
||||||
|
return this;
|
||||||
|
},
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
When we're routed to the [[index]] method, all we need to do is render
|
||||||
|
the index:
|
||||||
|
|
||||||
|
<<application>>=
|
||||||
|
index: function() {
|
||||||
|
this._index.render();
|
||||||
|
},
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
When we are routed to a product, we need to find that product, get its
|
||||||
|
view if it has one or create one if it doesn't, then call render:
|
||||||
|
|
||||||
|
<<application>>=
|
||||||
|
item: function(id) {
|
||||||
|
var product = this._products.getByCid(id);
|
||||||
|
if (_.isUndefined(product._view)) {
|
||||||
|
product._view = new ProductView({model: product,
|
||||||
|
cart: this._cart});
|
||||||
|
}
|
||||||
|
product._view.render();
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
@
|
||||||
|
|
||||||
|
And that's the entirety of the application.
|
||||||
|
|
||||||
|
\section{Initialization}
|
||||||
|
|
||||||
|
Initialization for most single-page applications happens when the DOM
|
||||||
|
is ready. So I'll do exactly that.
|
||||||
|
|
||||||
|
This should be obvious, except what the Hell is that when/then
|
||||||
|
construct? That's a new feature of jQuery 1.5 called Deferreds (also
|
||||||
|
known as Promises or Futures). All jQuery 1.5 ajax calls are
|
||||||
|
Deferreds that return data when you dereference them; [[when()]] is an
|
||||||
|
instruction to wait until the ajax call is done, and [[then()]] is a
|
||||||
|
chained instruction on what to do next.
|
||||||
|
|
||||||
|
This is a trivial example, but when you have multiple streams of data
|
||||||
|
coming in (say, you're loading independent schemas, or you have
|
||||||
|
multiple, orthagonal data sets in your application, each with their
|
||||||
|
own URL as per the Richardson Maturity Model), you can pass the array
|
||||||
|
of ajax objects to [[when()]] and [[then()]] won't fire until they're
|
||||||
|
all done. Automagic synchronization is a miracle.
|
||||||
|
|
||||||
|
<<initialization>>=
|
||||||
|
$(document).ready(function() {
|
||||||
|
var fetch_items = function() {
|
||||||
|
return $.ajax({
|
||||||
|
url: 'data/items.json',
|
||||||
|
data: {},
|
||||||
|
contentType: "application/json; charset=utf-8",
|
||||||
|
dataType: "json"
|
||||||
|
});
|
||||||
|
};
|
||||||
|
|
||||||
|
$.when(fetch_items()).then(function(data) {
|
||||||
|
new BackboneStore(data);
|
||||||
|
Backbone.history.start();
|
||||||
|
});
|
||||||
|
});
|
||||||
|
@
|
||||||
|
And that's it. Put it all together, and you've got yourself a working
|
||||||
|
Backbone Store.
