------解决方案-------------------- <script>  
 function flow(){ 
 	x = event.x; 
 	y = event.y; 
 	var obj = document.getElementById( "pad "); 
 	obj.style.left = x; 
 	obj.style.top = y;   
 } 
 function init(){ 
 	var obj = document.getElementById( "pad "); 
 	document.body.onmousemove = flow; 
 	obj.style.visibility =  "visible "; 
 } 
  </script>    
  <input type= "button " onclick= "init(); ">  
  <div id= "pad " style= "position:absolute;left:0px;top:0px;width:100px;height:100px;background-color:red;visibility:hidden; ">  </div>
