[roberto68]

I've form consisting of multiple fileds and I need to disable sumit button unless user fill smth in those fileds ( all of the requiered ones). I've smth like this

 $(document).ready(function() {        $("#submit").attr('disabled', 'disabled');     $("#eventName").keyup(function(){    // treba prerobit        if($(this).val() != '') {     $("#myText").keyup(function(){          if($(this).val() != '') {if (document.getElementById("start").value() !=""){ // mozno tiez (function){

but this is not dong the work. wouldn't be smth like while(1) and chcek if every filed is filled ( .val() !='') - wtih some timer ?
