This article introduces seven methods for refreshing frame subpages in JavaScript. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The following takes three pages named framedemo.html, left.html, and right.html as an example to explain how to do it.

The framedemo.html consists of two pages, the left and right. The code is as follows:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
< HTML>
< HEAD>
< TITLE> frameDemo </TITLE>
< /HEAD> 
< frameset cols="200,*">
< frame name=top src="left.html">
< frame name=button src="right.html">
< /frameset>
< /HTML>

Copy after login

Now assuming that left.html, the page above, has a button to refresh the page below, you can use the following There are seven types of statements, it’s up to you which one is easier to use.

//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(&#39;bottom&#39;).location.reload();

//语句6
window.parent.bottom.location.reload();

//语句7
window.parent[&#39;bottom&#39;].location.reload();

Copy after login

Explain:

1.window refers to the current page, for example, in this example it refers to the top.html page.

2.parent refers to the parent page of the current page, which is the frame page that contains it. For example, for this example it refers to framedemo.html.

3.frames is a window object and an array. Represents all subpages within the frame.

4.item is a method. Returns the elements in the array.

5. If the subpage is also a frame page with other subpages inside, then some of the above methods may not work.
top.html source code; (There are seven buttons on the page, the functions of which are to refresh the frame page below)

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
< HTML>
< HEAD>
< /HEAD>
< BODY>
< input type=button value="刷新1" onclick="window.parent.frames[1].location.reload()"><br>
< input type=button value="刷新2" onclick="window.parent.frames.bottom.location.reload()"><br>
< input type=button value="刷新3" onclick="window.parent.frames[&#39;bottom&#39;].location.reload()"><br>
< input type=button value="刷新4" onclick="window.parent.frames.item(1).location.reload()"><br>
< input type=button value="刷新5" onclick="window.parent.frames.item(&#39;bottom&#39;).location.reload()"><br>
< input type=button value="刷新6" onclick="window.parent.bottom.location.reload()"><br>
< input type=button value="刷新7" onclick="window.parent[&#39;bottom&#39;].location.reload()"><br>
< /BODY>
< /HTML>

Copy after login

The following is the source code of the right.html page, in order to prove that the page below has indeed been refreshed , a dialog box pops up after the page is loaded.

< HTML>
< HEAD>

1 history.go( 0)
2 location.reload()
3 location=location
4 location.assign(location)
5 document.execCommand('Refresh')
6 window.navigate(location)
7 location.replace(location)
8 document.URL=location.href

Method to automatically refresh the page:

1. Automatically refresh the page: Add the following code to the area

2. The page automatically jumps: add the following code to the area

<meta http-equiv="refresh" content="20;url=http://www.wyxg.com">

Copy after login

where 20 means jumping to the http://www.wyxg.com page after 20 seconds

3. The page automatically refreshes the js version

<script language="JavaScript">
function myrefresh()
{
       window.location.reload();
}
setTimeout(&#39;myrefresh()&#39;,1000); //指定1秒刷新一次
</script>

How does ASP.NET output the refresh parent window script statement

1.   this.response.write("<script>opener.location.reload();</script>");  
2.   this.response.write("<script>opener.window.location.href = opener.window.location.href;</script>");   
3.   Response.Write("<script language=javascript>opener.window.navigate(&#39;&#39;你要刷新的页.asp&#39;&#39;);</script>")
