jQuery Forum

Add event to each textbox:

 $('#zeteltoto_form input[type=text]').blur .....
 // Then call the function: checkAll()

 Normally, you would just set the disabled property to true or false.  Here's my quick shortcut in a somewhat non-jQuery fashion:

$("#verzend")[0].disabled = true;//disabled
$("#verzend")[0].disabled = false;//enabled

 Thanks for your answers, but both solutions didn't work.

Is there another way to check if all fields in a form are filled out?

1. jQuery.fn.checkAll = function() {
2.       $('input[type=text]').each(function(index, element) {
3.             if ($(this).val() == '') {
4.                   $('input[type=submit]').attr("disabled","disabled");
5.                   return false;
6.             } else {
7.                   $('input[type=submit]').removeAttr('disabled');
8.             }
9.       });
10. }
11. $('input[type=text]').bind('mouseenter mouseleave focus blur keypress', function() {
12. $(this).checkAll();
13. });
