window.open()方法实现弹出窗居中显示

Javascript代码

functionopenwindow(url,name,iWidth,iHeight)

 {

  varurl;                                 //转向网页的地址;

  varname;                           //网页名称，可为空;

  variWidth;                          //弹出窗口的宽度;

  variHeight;                       //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');

 }

使用时调用这个函数即可。如：

<ahref="javascript:void(0);" target="_blank" rel="external nofollow" οnclick="javascript:openwindow('a.html','',400,200);">转到a</a>
