I am debugging asp.net web page to make it look like Internet Explorer IE11 where closing the last tab will bring the close button of the previous tab to the mouse position. My tabcontainer has tabs with spans in it.

I tried this one:

var i=1;var count=1;
         function removeAt(tabPanelClientID, index) {
             if (index == i)
             {
                 var prevTabPanel = $get('__tab_TabContainerMain_TabPanel' + (index - 1));
                 alert('ptp=' + prevTabPanel+' width='+prevTabPanel.style.width);
             }
             count--;
     }

the output is this.

prevTabPanel.style.width didn't work. How to get width of the tab panel's header?
Thanks in advance
EDIT: I tried it with prevTabPanel.width(); I got error as 'undefined'
