HTML Export to Excel using JavaScript ,WORKING IN FIREFOX but NOT IN IE & CHROME

问题

I have a database generated table using PHP .

For exporting the table , I am using the following code to save its contents in .xls format.

Previously this script was working fine in Chrome , but now it has stopped ...when I click the button then a window opens but NO FILE GETS DOWNLOADED.....?

BUT IN FIREFOX it works

What may be the problem in Chrome ? How do I find out that problem , is there any tool to find out the script problem in Chrome?

Please help.

$( "#Export" ).click(function() {  
    var Contents = $('#MyTable').html();    
    alert(''+Contents);
    window.open('data:application/vnd.ms-excel, ' +  '<table>'+encodeURIComponent($('#MyTable').html()) +  '</table>' );
    alert('exporting records...');
});

In Chrome , both the Message boxes are also displayed, but no file gets saved on my PC. It was previously working without any problem but I don't know why it has stopped now.
