js

window.οnlοad=function(){	var oDiv1=document.getElementById('div1');	var oDiv2=document.getElementById('div2');		drag(oDiv1);	drag(oDiv2);	function drag(obj)	{		obj.οnmοusedοwn=function(ev){			var oEvent=ev||event;			var disX=oEvent.clientX-obj.offsetLeft;			var disY=oEvent.clientY-obj.offsetTop;			obj.οnmοusemοve=function(ev){				var oEvent=ev||event;				var left=oEvent.clientX-disX;				var top=oEvent.clientY-disY;								obj.style.left=left+'px';				obj.style.top=top+'px';			};			obj.οnmοuseup=function(){				obj.οnmοusemοve=null;				obj.οnmοuseup=null;				obj.releaseCapture&&obj.releaseCapture();			};			obj.setCapture&&obj.setCapture();			return false;		};	}};
