window.open打开窗口居中的方法

 

本例使用“(screen.width-width)/2”和“(screen.height-height)/2”获取窗体居中的坐标点,然后指定窗体的“left”和“top”属性。

 

 

javascript代码为

 

<html>
<head>
<title>标题页</title>
<script language="javascript">
//参数-url表示要打开的网站,winname表示打开后的窗体名称
//参数windth表示打开窗体的宽度,height表示打开窗体的高度
<!--
function openwindow( url,winName,width,height)
{
xposition=0; yposition=0;
if ((parseInt(navigator.appVersion) >= 4 ))
{
xposition = (screen.width - width) / 2;                //窗体居中的x坐标
yposition = (screen.height - height) / 2;             //窗体居中的y坐标
}
theproperty= "width=" + width + ","                     //打开窗口的属性
+ "height=" + height + ","
+ "location=0,"
+ "menubar=0,"
+ "resizable=1,"
+ "scrollbars=0,"
+ "status=0,"
+ "titlebar=0,"
+ "toolbar=0,"
+ "hotkeys=0,"
+ "screenx=" + xposition + ","                       //仅适用于Netscape
+ "screeny=" + yposition + ","                       //仅适用于Netscape
+ "left=" + xposition + ","                      //IE
+ "top=" + yposition;                                //IE
window.open( url,winName,theproperty );                //打开窗口
}//-->
</script>
