I am having an issue with Firefox for jquery ajax post. This functionality is working IE (not in Firefox). In IE controller is reaching to [webmethod] in server side. But this is not happening to Firefox.

I don't understand the problem. I place JavaScript debug in firebug, nothing showing there too.

1. var save = function(saveUrl) { 

   var $value = $("#Body_hiddenClientId");

    var $container = $("#grid"); 

   var handsontable = $container.data('handsontable'); 

   var tableData = JSON.stringify(handsontable.getData()); 

   var input = JSON.stringify({ "input": tableData }); 

   $.ajax({ 

   url: saveUrl, 

   type: 'POST', 

   dataType: 'json', 

   data: input, 

   contentType: 'application/json; charset=utf-8', 

   success: function(res) { 

            if (res.d === 'ok') { // handsontable('render'); 

            $('#grid').handsontable('destroy'); 

            getData(); }

    $.unblockUI(); 

   }, 

   error: function (xhr) { 

   alert(JSON.stringify(xhr.responseText)); // alert(xhr); 

   } 

   });

    };

Update:

finally I captured watch window in firebug. After this error page is refreshing.. It is hard to hold error.
