 上述方法，在FF下是无用 报错（e is undifind），原来FF不支持直接的event，解决方法是不直接利用event属性，用下面的代码即可

 function getEvent() //同时兼容ie和ff的写法
        {  
            if(document.all)   return window.event;    
            func=getEvent.caller;        
            while(func!=null){  
                var arg0=func.arguments[0];
                if(arg0)
                {
                  if((arg0.constructor==Event || arg0.constructor ==MouseEvent) || (typeof(arg0)=="object" && arg0.preventDefault && arg0.stopPropagation))
                  {  
                  return arg0;
                  }
                }
                func=func.caller;
            }
            return null;
        }

 //获取鼠标位置GetPostion 
         function GetPostion() {
              var e=getEvent();
              var x = getX(e);
              var y = getY(e);
              return [x, y]
           }

         function getX(e) {
               
             return e.pageX || e.clientX + document.body.scrollLeft - document.body.clientLeft
           }

         function getY(e) {
             
            return e.pageY || e.clientY + document.body.scrollTop - document.body.clientTop
          }
