1// See: http://www.reach1to1.com/sandbox/jquery/testform.html
2// Changes for ActionKit:
3//
4// Tacked a call to actionkit.forms.onPrefillerLoaded() at the end.
5//
6// Also made it check that an argument is *defined* rather than if
7// it's *true*, so passing in {somefield: ''} works
8//
9// Also, made it call onchange() if one is setup.  Used by the
10// donation form to keep Total updated, for example.

12/**
13 * This function sets the values of form element variables from an array
14 * This is the reverse process of Mark Constable's serialize function
15 * It is expected to be used as a call back for an ajax call that retrieves the form data
16 * @param data : array or hash containing name,value pairs for elements in the form
17 *
18 * Examples
19 *
20 * 1. Deserialize from an array
21 *    $('#form-id').deserialize([{'name':'firstname','value':'John'},{'name':'lastname','value':'Resig'}]);
22 *
23 * 2. Deserialize from a hash(object)
24 *    $('#form-id').deserialize({'firstname':'John','lastname':'Resig'});
25 *
26 * 3. Deserialize multiple config for select/radio/checkbox
27 *    $('#form-id').deserialize({'toppings':['capsicum','mushroom','extra_cheese'],'size':'medium'})
28 * which will set the corresponding select/radio/checkbox config for toppings
29 *
30 * 3. Deserialize multiple config for select/radio/checkbox and with isPHPnaming = true
31 *    $('#form-id').deserialize({'toppings':['capsicum','mushroom','extra_cheese'],'size':'medium'},{isPHPnaming:true})
32 * which will set the corresponding select/radio/checkbox config for toppings, but will ignore select names ending with []
33 *
34 * @return         the jQuery Object
35 * @author         Ashutosh Bijoor ([email protected])
36 * @version        0.35
