JS弹出新窗口

小编今天在防战中遇到一串js代码,经过百度,原来是弹出一个新窗口并且在页面居中.以下是代码:

<script>
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');


    window.open("notice.html","newwindow",'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>

在页面调用:<a href="javascript:void(0);" onclick="javascript:openwindow('BrokenLinkRecords.html','',800,400);">转到a</a>
