Revision history
|
||||||
|
----------------
|
||||||
|
v1.0.1 - 4 Dec 2008
|
||||||
|
- Extended $.getValidJSON(params) API so you can define
|
||||||
|
{ schema : { send : xxx, receive : zzz } } so you can
|
||||||
|
optionally validate data on the way out and on the way in.
|
||||||
|
- Added tests to ensure that the schema key defined does really
|
||||||
|
exist as a typeof "object" in validJSONSchemas.
|
||||||
|
|
||||||
|
v1.0.0 - 3 Dec 2008
|
||||||
|
- initial release
|
||||||

Implementation overview
|
||||||
|
-----------------------
|
||||||
|
NOTE: This work contributes to the SOAPjr Data Model Definition project
|
||||||
|
that is designed to encourage the adoption and use of common JSON
|
||||||
|
data models with common SOAPjr APIs.
|
||||||
|
|
||||||
|
See http://soapjr.org/specs.html#dmd for more information
|
||||||
|
|
||||||
|
1. Include the jquery.js, jsonschema-b2.js and jquery.ValidJSON.js src files
|
||||||
|
into your html page - optionally include the jquery.SOAPjr.js plugin too
|
||||||
|
|
||||||
|
2. Add a call to the $(document).ready(function() { ... }) block to load
|
||||||
|
the relevant JSON Schema definition files you require
|
||||||
|
|
||||||
|
e.g.
|
||||||
|
- http://soapjr.org/schemas/SOAPjr_request
|
||||||
|
- see http://json-schema.org/shared.html for common formats
|
||||||
|
|
||||||
|
3. Get the JSON files/objects you require using the $.getValidJSON() API
|
||||||
|
|
||||||
|
4. Check the "result.valid" boolean and "result.errors" array for any
|
||||||
|
validation errors and if all is good then use "json" like normal.
|
||||||
|
|
||||||
|
5. Sleep well knowing your data is cleanly validated and conforms to your
|
||||||
|
chosen schema.
|
||||||
|
|
||||||
|
|
||||||
|
Code usage examples
|
||||||
|
-------------------
|
||||||
|
1. Include src files
|
||||||
|
|
||||||
|
<script type="text/javascript" src="jquery-1.2.6.js"></script>
|
||||||
|
<script type="text/javascript" src="jsonschema-b2.js"></script>
|
||||||
|
<script type="text/javascript" src="jquery.ValidJSON.js"></script>
|
||||||
|
|
||||||
|
|
||||||
|
2. Add calls to load schema files
|
||||||
|
|
||||||
|
<script type="text/javascript">
|
||||||
|
$(document).ready(function() {
|
||||||
|
//load them from a URL
|
||||||
|
$.getValidJSONSchemas({
|
||||||
|
//id //url
|
||||||
|
"card" : "http://json-schema.org/card",
|
||||||
|
"calendar" : "http://json-schema.org/calendar"
|
||||||
|
});
|
||||||
|
|
||||||
|
//import them from a local var
|
||||||
|
$.setValidJSONSchemas({
|
||||||
|
//id //pre-populated vars (possibly included in .js files)
|
||||||
|
"geo" : geoschema_var,
|
||||||
|
"address" : addressschema_var
|
||||||
|
});
|
||||||
|
});
|
||||||
|
</script>
|
||||||
|
|
||||||
|
NOTE: cross-domain xhr restrictions apply - look at JSONP for cross domain requests
|
||||||
|
|
||||||
|
|
||||||
|
3. Get the JSON files/objects
|
||||||
|
|
||||||
|
<script type="text/javascript">
|
||||||
|
function do_your_stuff() {
|
||||||
|
//collect data from a form or setup a stub
|
||||||
|
var params = { ... };
|
||||||
|
|
||||||
|
//get your data and validate it in one call
|
||||||
|
var xhr = $.getValidJSON({
|
||||||
|
"url" : url, //required
|
||||||
|
"data" : params, //optional
|
||||||
|
"callback" : "my_callback", //required (see point 4 below)
|
||||||
|
"schema" : { "send":"schema_id1", "receive":"schema_id2" } //optional - can be defined within the response JSON object using $schema
|
||||||
|
});
|
||||||
|
}
|
||||||
|
</script>
|
||||||
|
|
||||||
|
|
||||||
|
4. Check the validation results/errors
|
||||||
|
|
||||||
|
<script type="text/javascript">
|
||||||
|
//setup your callback to handle the json data and any validation errors
|
||||||
|
function my_callback(result, json) {
|
||||||
|
if (result.valid) {
|
||||||
|
//json contains a valid XXX data object
|
||||||
|
} else {
|
||||||
|
for (var e in result.errors) {
|
||||||
|
//e.property tells you which value is invalid
|
||||||
|
//e.message is a human readable error message
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
</script>
|
||||||
|
|
||||||
|
|
||||||
|
5. Relax
|
||||||
|
|
||||||
|
This plugin will let you do field level schema based validation.
|
||||||
|
You can also connect this to your form validation for standardised form data.
|
||||||
|
And you can use it in combination with the SOAPjr plugin to make sure
|
||||||
|
your apps handle metadata and complex/multiple errors seamlessly.
|
||||||
|
|
||||||
|
