I have a form with some input texts passed in GET, and i don't want to have in GET all the fields; i want to avoid empty fields.

So, a concrete example for:

<form method="GET" action="an_url">
    <input type="text" name="field1"/>
    <input type="text" name="field2"/>
    <input type="text" name="field3"/>
    <input type="submit" value="submit"/>
</form>

I supposed that fields disabled by html attribute "disabled" shouldn't be passed to GET.

So i have done a js (based on jquery) to disable empty fields on submit, something like this:

     $("form").submit(function() {
         $(this).find("input[type=text]").each( function () {

            if (!$.trim($(this).val())) {
                $(this).attr("disabled", "true");
            }
         });
     });

However, this doesn't work. Any ideas?
