当点这张力片的时刻弹出DIV。并在上面显示了一些相关信息

<img src="../../Content/Image/jm_pic.jpg" border="0" style="cursor: pointer;" alt="点击加盟我们"
onmousedown="showPopup(360,240);" />

<script type="text/javascript" language="javascript">
var baseText=null;
function showPopup(w,h)
{
var isIE=!!window.ActiveXObject;
var isIE8=isIE&&!!document.documentMode;//IE8
var clientHeight=0.80;
if (isIE)
{
if (isIE8)
{
clientHeight=0.50;
}

}
var popUp = document.getElementById("popupcontent");
popUp.style.top = document.body.clientHeight*clientHeight + "px";
popUp.style.left = document.body.clientWidth*0.45 + "px";
popUp.style.width = w + "px";
popUp.style.height = h + "px";
if (baseText == null) baseText = popUp.innerHTML;
popUp.innerHTML = baseText + "<div id=\"statusbar\"></div>";
var sbar = document.getElementById("statusbar"); sbar.style.marginTop = (parseInt(h)-299) + "px"; popUp.style.visibility = "visible";
}
function hidePopup()
{ var popUp = document.getElementById("popupcontent");
popUp.style.visibility = "hidden";
}
</script>
