window.open() 弹出窗体居中
<script type="text/javascript">
function openwindow(url,name,iWidth,iHeight) {
var url; //转向网页的地址;
var name; //网页名称,可为空;
var iWidth; //弹出窗口的宽度;
var iHeight; //弹出窗口的高度;
var iTop = (window.screen.availHeight-30-iHeight)/2; //获得窗口的垂直位置;
var iLeft = (window.screen.availWidth-10-iWidth)/2; //获得窗口的水平位置;
window.open(url,name,'height='+iHeight+',innerHeight='+iHeight+',width='+iWidth+',innerWidth='+iWidth+',top='+iTop+',left='+iLeft+',toolbar=no,menubar=no,scrollbars=auto,resizeable=no,location=no,status=no');
}
</script>
使用时调用这个函数即可。如:
<a href="#" onclick="openwin('url','name',585,630)" > 我要回答</a>
