preventDefault（）不起作用

Question

//prevent default handler
function click_handler(event){            
  if(event.shiftKey){
      event.preventDefault();
  }
}
//event listener
var file_mgmt=document.querySelector('div.filemanager'); 
if(window.addEventListener){
        file_mgmt.addEventListener('click',click_handler,false);
    }else if(window.attachEvent){
        file_mgmt.attachEvent('onclick',click_handler);
    }else{
        file_mgmt.onclick=click_handler;
    }

basically file_mgmt is a div container which is enclosed with tag linking to another links. Since Shift+click opens the link in new _blank tab i want to prevent it since it will damage the original page layout.

Giving up after a while, i even tried following from Mozilla doc: Event.preventDefault() , the result being the same.

Any Suggestions?

Preventing default action when clicking on a div will not do anything since by default it doesn't do anything anyway. You should attach the click handler to the actual link instead.
