darg(opTest);function darg(obj){
//鼠标按下
obj.onmousedown = function(ev){
//IE直接用event或者window.event得到事件本身,而在其他浏览器函数要获取到事件本身需要从函数中传入
var oevent = ev || event;
var distanceX = oevent.clientX - this.offsetLeft;
var distanceY = oevent.clientY - this.offsetTop; //鼠标移动
document.onmousemove = function(ev){
var oevent = ev || event;
obj.style.left = oevent.clientX - distanceX + 'px';
obj.style.top = oevent.clientY - distanceY + 'px';
}; //鼠标放开
document.onmouseup = function(){
document.onmousemove = null;
