window.open()方法實作彈出窗居中顯示

Javascript代碼

functionopenwindow(url,name,iWidth,iHeight)

 {

  varurl;                                 //轉向網頁的位址;

  varname;                           //網頁名稱，可為空;

  variWidth;                          //彈出視窗的寬度;

  variHeight;                       //彈出視窗的高度;

  var iTop =(window.screen.availHeight-30-iHeight)/2;       //獲得視窗的垂直位置;

  var iLeft =(window.screen.availWidth-10-iWidth)/2;          //獲得視窗的水準位置;

  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');

 }

使用時調用這個函數即可。如：

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