jquery - onbeforeunload issue in IE browser -

i using below code leaving current page. works fine in chrome , mozilla, calling every anchor tags in ie 10 browser. can prevent calling in ie 10 browser?

window.onbeforeunload = function() {       return  ""; }; 

this default behavior of ie, need remove onbeforeunload event anchor tag while hovering on it:

$(document).ready(function(){     //store onbeforeunload later use     $(window).data('beforeunload',window.onbeforeunload);          //remove||re-assign onbeforeunload on hover      $('a')       .hover(               function(){window.onbeforeunload=null;},              function(){window.onbeforeunload=$(window).data('beforeunload');}             );   }); 

or need 'return false' onclick event of each anchor tag:

<a onclick="somefunction(); return false;" href="lnk" >my link</a>
