Question

div层可拖动为什么没反应，求大神指导？？？

css里面：
#set_BgImage {
width:600px;
height:600px;
border:1px solid #FA9F22;
margin:0px auto;
border-radius:10px;
position:absolute;
}
.set_Head1 {
width:600px;
height:50px;
background-color:#FA9F22;
border:1px solid #FA9F22;
border-radius:10px;
cursor:pointer;
position:absolute;
}
JS里面：
var a;
document.onmouseup = function () {

if (!a) return;
document.all ? a.releaseCapture() : window.captureEvents(Event.MOUSEMOVE | Event.MOUSEUP);
a = "";

};
document.onmousemove = function (d) {

if (!a) return;
if (!d)
d = event;
a.style.left = (d.clientX - b) + "px";
a.style.top = (d.clientY - c) + "px";
};
function Drag(o, e) {

a = o; document.all ? a.setCapture() : window.captureEvents(Event.MOUSEMOVE);
b = e.clientX - parseInt(a.style.left);
c = e.clientY - parseInt(a.style.top);
}

body里面：

<div id="set_BgImage">
<div class="set_Head1" onmousedown="Drag(this,event)"></div>
</div>

亲，你用的浏览器是哪个，如果是chrome或者火狐这些，那肯定是没有效果的，因为这些浏览器的事件对象能直接用event

追问

我是使用谷歌浏览器，和IE8
