window.open打开页面居中显示
<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; //window.screen.height获得屏幕的高,window.screen.width获得屏幕的宽 var iTop = (window.screen.height-30-iHeight)/2; //获得窗口的垂直位置; var iLeft = (window.screen.width-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>
<a href="javascript:void(0);" onclick="javascript:openwindow('a.html','',400,200);">转到a</a>
还有一种方法,这个是cnblogs发帖时最下面Tag标签的代码:
<div class="itemspace"> Tag标签: <input name="Editor$Edit$Advanced$txbTag" type="text" id="Editor_Edit_Advanced_txbTag" style="width: 500px" /> <a onclick="leftVal = (screen.width - 300) / 2;topVal = (screen.height - 500) / 2;window.open( 'InsertTag.aspx','_blank','width=300,height=500,toolbars=yes,resizable=yes,scrollbars=yes,left='+leftVal+',top='+topVal);return false" href="#">插入已有标签</a> (多个关键字之间用“,”分隔,最多不超过10个)</div> <div class="itemspace">
