jQuery AJAX GET html data IE8 not working

Question

This is the code but it's not working on IE8 & 7 (IE9 , chrome,firefox, safari,opera are all ok). I have tried a lot of things (meta utf-8 code, php header code, taking alerts, cache:false).What can i do , i need help. Thanks for your interests.

        var request = $.ajax({
          type:"GET",
          url: "_veri.php?t=icerik_getir&id="+tabopen,
          dataType: "html",
        });
        request.done(function(msg) {
            $(".tab-contentmenu").html(msg);
        });

EDIT:

alert gives me the data of requested in all browsers but still no requested data in ".tab-contentmenu" , what should i do?

            var request = $.ajax({
            type:"GET",
            context: document.body,
            url: "_veri.php?t=icerik_getir&id="+tabopen,
            dataType: "html"
            });
            request.done(function(msg) {
              $(".tab-contentmenu").html(msg);
              alert(msg);
            });

I solved the problem , in php file there was a unclosed div and I removed it.
