jQuery Forum

I'm using jQuery Validate to validate my on-line things.

it looks like a plugin issue, but my turn-arround was on ajax/param not on the plugin, so i put it on core.

Today i faced a problem, that is: i use remote validation and i needed that all the form is submited to the validation. (this remote validation is like a bridge to the $.ajax)

i have tried this, and of it is not the best deal, because it get the form on ready and don't change when the form change:

1.     $('#nome').rules('add',
2.     {
3.         remote:
4.         {
5.             url: 'br/com/evodata/ajax/validaItemNome.php',
6.             type: 'post',
7.             data: $('#commentForm').serializeArray()
8.         }
9.     });

Then i think about put a function on it.

1.     $('#nome').rules('add',
2.     {
3.         remote:
4.         {
5.             url: 'br/com/evodata/ajax/validaItemNome.php',
6.             type: 'post',
7.             data: function () {return $('#commentForm').serializeArray()}
8.         }
9.     });

And for my surprise, it doesn't work

It don't seems to check if data is a function and call it.

i put an work-around on the param: function that check and parse the data.

1. // Serialize an array of form elements or a set of
2.     // key/values into a query string
3.     param: function( a, traditional ) {
4.         var s = [],
5.             add = function( key, value ) {
6.                 // If value is a function, invoke it and return its value
7.                 value = jQuery.isFunction( value ) ? value() : value;
8.                 s[ s.length ] = encodeURIComponent( key ) + "=" + encodeURIComponent( value );
9.             };
10.         // Set traditional to true for jQuery <= 1.3.2 behavior.
11.         if ( traditional === undefined ) {
12.             traditional = jQuery.ajaxSettings.traditional;
13.         }
14.         if (jQuery.isFunction(a))
15.         {
16.             a = a();
17.         }
18.         // If an array was passed in, assume that it is an array of form elements.
19.         if ( jQuery.isArray( a ) || ( a.jquery && !jQuery.isPlainObject( a ) ) ) {
20.             // Serialize the form elements
21.             jQuery.each( a, function() {
22.                 add( this.name, this.value );
23.             });
24.         } else {
25.             // If traditional, encode the "old" way (the way 1.3.2 or older
26.             // did it), otherwise encode params recursively.
27.             for ( var prefix in a ) {
28.                 buildParams( prefix, a[ prefix ], traditional, add );
29.             }
30.         }
31.         // Return the resulting serialization
32.         return s.join( "&" ).replace( r20, "+" );
33.     }
34. });

Is someone else with similar problems?

What do you think of that solution?

Is this feature desirable for jQuery ajax?
