JS：

復制代碼代碼如下:

<script type="text/javascript"> 
var mouseover=true
var xcoor;
var ycoor;
function coordinates()
{

if (event.srcElement.id.indexOf("wishbroad") == 0)
    {
    event.srcElement.style.zIndex = 1000;
    mouseover=true;
    pleft=event.srcElement.style.pixelLeft;
    ptop=event.srcElement.style.pixelTop;
    xcoor=event.clientX;
    ycoor=event.clientY;
    document.onmousemove=moveImage;
    }
}

function moveImage()
{
if (mouseover&&event.button==1)
    {
    event.srcElement.style.pixelLeft=pleft+event.clientX-xcoor;
    event.srcElement.style.pixelTop=ptop+event.clientY-ycoor;
    return false;
    }
}

function mouseup()
{
    event.srcElement.style.zIndex = 1;
    mouseover=false;
}
document.onmousedown=coordinates;
document.onmouseup=mouseup;
</script>
