8 ways to refresh frame subpages with JavaScript __jsonp

8 ways to refresh a frame's subpages with JavaScript first look at a simple example:
The following three pages are named Frame.html, top.html, bottom.html as examples to specify how to do.

Frame.html consists of two pages (bottom.html) on top (top.html) with the following code:
<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 transitional//en" >
< HTML >
< head >
< title > Frame </title >
< frameset rows = "50%,50%" >
< frame name =top src = "top.html" >
< frame name =bottom src = "bottom.html" >
</Frameset >
</HTML >

Now assume that top.html (that is, the page above) has seven button to achieve the bottom.html (that is, the following page) of the refresh, you can use the following seven kinds of statements, which easy to do with their own.

Statement 1. Window.parent.frames[1].location.reload ();
Statement 2. Window.parent.frames.bottom.location.reload ();
Statement 3. window.parent.frames["Bottom"].location.reload ();
Statement 4. Window.parent.frames.item (1). Location.reload ();
Statement 5. Window.parent.frames.item (' Bottom '). Location.reload ();
Statement 6. Window.parent.bottom.location.reload ();
Statement 7. window.parent[' Bottom '].location.reload ();

The code for the Top.html page is as follows: <! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 transitional//en" >
< HTML >
< head >
< title > top.html </title >
< BODY >
< input type =button value = "Refresh 1" onclick = "window.parent.frames[1].location.reload ()" >< br >
< input type =button value = "Refresh 2" onclick = "window.parent.frames.bottom.location.reload ()" >< br >
< input type =button value = "Refresh 3" onclick = "window.parent.frames[' Bottom '].location.reload ()" >< br >
< input type =button value = "Refresh 4" onclick = "Window.parent.frames.item (1). Location.reload ()" >< br >
< input type =button value = "Refresh 5" onclick = "window.parent.frames.item (' Bottom '). Location.reload ()" >< br >
< input type =button value = "Refresh 6" onclick = "window.parent.bottom.location.reload ()" >< br >
< input type =button value = "Refresh 7" onclick = "window.parent[' Bottom '].location.reload ()" >< br >
</Body >
</HTML >
The following is the bottom.html page source code, in order to prove that the bottom page is indeed refreshed, after loading the page pop-up a dialog box.

The code for the Bottom.html page is as follows:
<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 transitional//en" >
< HTML >
< head >
< title > bottom.html </title >
< body onload = "alert (' I was loaded. ') ' >
< H1 > This are the content in bottom.html. </H1 >
</Body >
</HTML >


Explain:
1.window refers to the current page, for example, for 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 is an array. Represents all the subpages within the frame.
4.item is the method. Returns the elements inside an array.
5. If the child page is also a frames page, inside or other sub pages, then some of the above methods may not work.

JavaScript refreshes the page in several ways:
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

Ways to automatically refresh pages:
1. Page Automatic refresh: Add the following code to the <meta http-equiv= "Refresh" content= ">"
20 of which means that the page is refreshed every 20 seconds.

2. Page Automatic Jump: Add the following code to the <meta http-equiv= "Refresh" content= "20;url=http://www.wyxg.com" >
20 of which refers to 20 seconds after the jump to the http://www.wyxg.com page

3. Page automatically refresh JS version
<script language= "JavaScript" >
function Myrefresh ()
{
Window.location.reload ();
}
SetTimeout (' Myrefresh () ', 1000); Specify 1 seconds to refresh once
</script>

Asp. NET how to output refresh the parent window script statement

JS Refresh Frame Script statement

How to refresh the page that contains the frame with
<script language=javascript>
Parent.location.reload ();
</script>

//Child window refreshes parent window
<script language=javascript>
    self.opener.location.reload ();
</script>
(or <a href= "javascript:opener.location.reload ()" > Refresh </a>   )

//How to refresh the page of another frame with    
<script language=javascript>
   Parent. Another FrameID.location.reload ();
</script>

Call the following statement in <body> if you want to refresh when you close the window or refresh when you want to open windows.

<body onload= "opener.location.reload ()" > Refresh when Windows
<body onunload= " Opener.location.reload () > Refresh

<script language= "javascript"
when shutdown Window.opener.document.location.reload ()
</script>

adds   onunload= to the body of the pop-up window. Window.opener.location.reload ();    close the pop-up window automatically refreshes the parent window.
