submit disabled fields

Why not simply enable all the disabled input fields right before the submission using .removeAttr() and .submit() .

$('#my_form').submit(function(){
    $("#my_form :disabled").removeAttr('disabled');
});

You can make your fields readonly, this will disallow changes to the value of your controls.

Edit: You could easily write a "serializeDisabled" function, iterating over the disabled form elements which have a name attribute and using the jQuery.param function at the end, to generate the serialized string:

(function ($) {
  $.fn.serializeDisabled = function () {
    var obj = {};

    $(':disabled[name]', this).each(function () { 
        obj[this.name] = $(this).val(); 
    });
    return $.param(obj);
  }
})(jQuery);

OK... perhaps I didn't ask my question clearly enough... but the answer I was looking for is here:

http://docs.jquery.com/Plugins:Forms#.val.28.29_becomes_.fieldValue.28.29

I mentioned ajaxSubmit() in my question, which comes from the jQuery Form plugin... and inside that plug-in there is a method called fieldValue() which accepts a parameter called "successful". If you pass in "true" then the plug-in only returns what the W3C defines as "successful" controls (which excludes disabled controls). but if you set it to false, then it will get all values, regardless of W3C definition.

I knew this was possible, since the entire submission is controlled by the plug-in and has nothing to do with the HTML standards/definition... I was just asking to see if this option was already available in this plug-in or other plugins. It is available in this plugin, although the default behavior is to act like a standard HTML submit

//jQuery('#container :input').serializeAll()

(function($j) {
  $j.fn.serializeDisabled=function(){
    var obj={};
    $j(this).filter(':input:disabled').each(function(index,domElem){
      var $this=$j(domElem);
      obj[domElem.name]=$this.val(); 
    });
    return $j.param(obj);
  };

  $j.fn.serializeAll=function(){
    $this=$j(this);
    return $this.filter(':input:enabled').serialize()+'&'+$this.serializeDisabled();
  };
})(jQuery);
