all inputs of a certain class to json

Question

I have this type of html:

<input id='a1' name='a1' value='111' class='hey'/>
<input id='b1' name='b1' value='222' class='hey'/>
<input id='c1' name='b1' value='333' class='hey'/>

and I need to obtain this json from it:

{ a1: '111', b1: '222', c1: '333' }

anybody knows how ?

That should be pretty easy:

var json = {};
$('input.hey').each(function() {
  json[this.name] = this.value;
});

There are serialization routines supplied by jQuery to (for example) vaccuum up a whole form, but in a case like this it's pretty easy to just roll your own.

var json = {};

$('input.hey').each(function(index) {
  json[$(this).attr('name')] = $(this).val();
});
