var returnVal = window.showModalDialog(url,args,'dialogHeight: ' + height + 'px;dialogWidth:' + width + 'px;status:no;help:no;resizable:yes;scroll:yes;center:yes;');
if (returnVal=="True")
{
window.location.href=window.location.href;
window.location.reload();
}
然后在打开的窗口中
<script>window.returnValue='True';window.close();</script>
