Do hidden form elements get submitted?

Question

If jQuery's toggle() is used on a <div> containing form elements, will those form elements get submitted with the form, even though they are hidden?

My code (though probably not needed for this particular question):

$('.cms_loop_title').click(function(){     $ctg = $(this).attr('rel');     $('.'+$ctg).toggle();     //alert($ctg); }); 

Answer 1

Yes, they'll get submitted unless they are removed from the document or have the disabled attribute set on them.

For more information, see the HTML5 Working Draft — Section 4.10.22.4 Constructing the form data set. The information there is more-or-less the same as previous HTML versions.

Answer 2

In order to prevent submitting, you have to disable the elements. Hiding doesn't do the trick (I had the same issue a while ago)
