javascript 刷新页面 关闭窗口[转]
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。
语句1. window.parent.frames[1].location.reload();
语句2. window.parent.frames.bottom.location.reload();
语句3. window.parent.frames["bottom"].location.reload();
语句4. window.parent.frames.item(1).location.reload();
语句5. window.parent.frames.item('bottom').location.reload();
语句6. window.parent.bottom.location.reload();
语句7. window.parent['bottom'].location.reload();
语句2. window.parent.frames.bottom.location.reload();
语句3. window.parent.frames["bottom"].location.reload();
语句4. window.parent.frames.item(1).location.reload();
语句5. window.parent.frames.item('bottom').location.reload();
语句6. window.parent.bottom.location.reload();
语句7. window.parent['bottom'].location.reload();
top.html 页面的代码如下:
1
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
2
<html>
3
<head>
4
<title>top.html </title>
5
</head>
6
<body>
7
<input type="button" value="刷新1" onclick="window.parent.frames[1].location.reload()"><br>
8
<input type="button" value="刷新2" onclick="window.parent.frames.bottom.location.reload()"><br>
9
<input type="button" value="刷新3" onclick="window.parent.frames['bottom'].location.reload()"><br>
10
<input type="button" value="刷新4" onclick="window.parent.frames.item(1).location.reload()"><br>
11
<input type="button" value="刷新5" onclick="window.parent.frames.item('bottom').location.reload()"><br>
12
<input type="button" value="刷新6" onclick="window.parent.bottom.location.reload()"><br>
13
<input type="button" value="刷新7" onclick="window.parent['bottom'].location.reload()"><br>
14
</body>
15

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。
bottom.html 页面的代码如下:
1
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
2
<html>
3
<head>
4
<title>bottom.html </title>
5
</head>
6
<body onload="alert('我被加载了!')">
7
<h1>
8
This is the content in bottom.html.</h1>
9
</body>
10
</html>

解释一下:
1.window指代的是当前页面,例如对于此例它指的是top.html页面。
2.parent指的是当前页面的父页面,也就是包含它的框架页面。例如对于此例它指的是framedemo.html。
3.frames是window对象,是一个数组。代表着该框架内所有子页面。
4.item是方法。返回数组里面的元素。
5.如果子页面也是个框架页面,里面还是其它的子页面,那么上面的有些方法可能不行。

2.页面自动跳转:把如下代码加入<head>区域中
<meta http-equiv="refresh" content="20;url=http://www.wyxg.com">
其中20指隔20秒后跳转到http://www.wyxg.com页面
3.页面自动刷新js版
1
<script language="JavaScript">
2

3
{
4

JS刷新框架的脚本语句
//如何刷新包含该框架的页面用
<script language=JavaScript>
parent.location.reload();
</script>
//子窗口刷新父窗口
<script language=JavaScript>
self.opener.location.reload();
</script>
( 或 <a href="javascript:opener.location.reload()">刷新</a> )
//如何刷新另一个框架的页面用
<script language=JavaScript>
parent.另一FrameID.location.reload();
</script>
<script language=JavaScript>
parent.location.reload();
</script>
//子窗口刷新父窗口
<script language=JavaScript>
self.opener.location.reload();
</script>
( 或 <a href="javascript:opener.location.reload()">刷新</a> )
//如何刷新另一个框架的页面用
<script language=JavaScript>
parent.另一FrameID.location.reload();
</script>
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。
1
<body onload="opener.location.reload()"> 开窗时刷新
2
<body onUnload="opener.location.reload()"> 关闭时刷新

<script language="javascript">
5
