js刷新页面 方法大全
本文转载于:http://www.jb51.net/article/14397.htm
一、先来看一个简单的例子:
下面以三个页面分别命名为frame.html、top.html、bottom.html为例来具体说明如何做。
frame.html 由上(top.html)下(bottom.html)两个页面组成,代码如下:
1
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
2
<HTML>
3
<HEAD>
4
<TITLE> frame </TITLE>
5
</HEAD>
6
<frameset rows="50%,50%">
7
<frame name=top src="top.html">
8
<frame name=bottom src="bottom.html">
9
</frameset>
10
</HTML>

现在假设top.html (即上面的页面) 有七个button来实现对bottom.html (即下面的页面) 的刷新,可以用以下七种语句,哪个好用自己看着办了。
1
top.html 页面的代码如下:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
4
<HTML>
5
<HEAD>
6
<TITLE> top.html </TITLE>
7
</HEAD>
8
<BODY>
9
<input type=button value="刷新1" onclick="window.parent.frames[1].location.reload()"><br>
10
<input type=button value="刷新2" onclick="window.parent.frames.bottom.location.reload()"><br>
11
<input type=button value="刷新3" onclick="window.parent.frames['bottom'].location.reload()"><br>
12
<input type=button value="刷新4" onclick="window.parent.frames.item(1).location.reload()"><br>
13
<input type=button value="刷新5" onclick="window.parent.frames.item('bottom').location.reload()"><br>
14
<input type=button value="刷新6" onclick="window.parent.bottom.location.reload()"><br>
15
<input type=button value="刷新7" onclick="window.parent['bottom'].location.reload()"><br>
16
</BODY>
17
</HTML>

下面是bottom.html页面源代码,为了证明下方页面的确被刷新了,在装载完页面弹出一个对话框。

二、自动刷新页面
1.页面自动刷新:把如下代码加入<head>区域中
![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)

![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
{
window.location.reload();
}
![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
三、java在写Servler,Action等程序时,要操作返回页面的话(如谈出了窗口,操作完成以后,关闭当前页面,刷新父页面)
1
PrintWriter out = response.getWriter();
2
out.write("<script type=\"text/javascript\">");
3
////子窗口刷新父窗口
4
out.write("self.opener.location.reload();");
5
//关闭窗口
6
out.write("window.opener=null;");
7
out.write("window.close();");
8
out.write("</script>");

四、JS刷新框架的脚本语句
1.如何刷新包含该框架的页面用

2.子窗口刷新父窗口

3.如何刷新另一个框架的页面用 (上面的实例以说明了)

![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
![](http://www.blogjava.net/Images/OutliningIndicators/None.gif)
4.如果想关闭窗口时刷新或者想开窗时刷新的话,在<body>中调用以下语句即可。
