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:

  code is as follows copy code

<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 transitional//en" >
<HTML>
<HEAD>
<TITLE> fra Me </TITLE>
</HEAD>
<frameset rows= "50%,50%" >
<frame name=top src= "top.html" >
<frame name=bottom src= "bottom.html" >
</frameset>


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:

The code is as follows Copy Code

<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 transitional//en" >
<HTML>
<HEAD>
<TITLE> Top . html </TITLE>
</HEAD>
<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>


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:

The code is as follows Copy Code

<body onload= "alert (' I was loaded!") ') ' >
</BODY>
</HTML>
