Js 中的 json pageX 和pageY，重复定义的原因是每移动一次就要重新获取一次？？？

Question

plane:function(oGameBox,e){             var x=e.pageX,                     y=e.pageY;//鼠标到浏览器的距离            var oPlane=new Image();//获取飞机图片             oPlane.src = 'img/plane.png';             oPlane.width=60;             oPlane.height=36;            var lx=oGameBox.offsetLeft+parseInt(oGameBox.style.borderWidth)+oPlane.width/2;             var ty=oGameBox.offsetTop+parseInt(oGameBox.style.borderWidth)+oPlane.height/2;                      var left=x-lx;             var top=y-ty;             oPlane.style.cssText="display:block;position:absolute;top:"+top+"px;left:"+left+"px;";//得到点击之后，飞机在鼠标出的位置             oGameBox.appendChild( oPlane );document.onmousemove=function(e){         e=e||window.event;         var top=e.pageY-ty;         var left=e.pageX-lx;         oPlane.style.top=top+'px';         oPlane.style.left=left+'px'; }
