jQuery ProgressBar and IE8

Question

I use jQuery progressbar in AJAX sync request. The Progressbar works fine in FireFox, but it always shows 100% in IE8.

This is my code:

var selectRows = $('#rowed3').getGridParam('selarrrow');
$.each(selectRows,function (index,id) {
  $.ajax({                            
          url:'addSign',
          success: function (result) {                                                 
        $("#progressbar").progressbar('option','value',currPercent);
         },
          async:false,
          data:{
          'id':id,
          'details':sign
               },
       type:'post'
});

When I add

alert('111')

before

$("#progressbar").progressbar('option','value',currPercent);

I have seen Progressbar change its' state.

Why does it not work in IE?

Sorry, but I have skipped some piece of code. I think it's important.

Answer 1

Is Internet Explorer set in Quirks mode? Because usually that messes up the progress bar.
