2.屏幕坐标位置


var div = document.getElementById("myDiv");
EventUtil.addHandler(div,"click",function(event){

   alert("Screen coordinates: "+event.screenX+","+event.screenY);
});




3.页面坐标位置


var div = document.getElementById("myDiv");
EventUtil(div,"click",function(event){
   event = EventUtil.getEvent(event);
   var pageX = event.pageX;
   var pageY = event.pageY;
   if(pageX==undefined)

     pageX=event.clientX+document.body.scrollLeft||document.documentElement.scrollLeft;
  }
   if(pageY==undefined)
   {
     pageY = event.clientY+document.body.scrollTop||document.documentElement.scrollTop;
   }
   alert("Page coordinates: "+pageX+","+pageY);
});
