The framework of the refresh has always been uncertain, now think of this problem, the solution is really quite a lot, here summed up the 7 ways to refresh the frame with JS, in any of the frames page to refresh the other frames page, or more practical, these 7 methods are:

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

Here is a framework to illustrate the use of these 7 methods, which includes three HTML pages:

Frame.html: The main frame, consisting of the top and bottom two child frames pages.
Top.html: On the frame.
Buttom.html: Next frame.
Assume that there is a refresh button in the top.html frame, and then click to refresh the contents of the frame bottom.html.
Main frame frame.html Code:

The code is as follows Copy Code
<HTML>
<HEAD>
<TITLE> Main Frame </TITLE>
</HEAD>
<frameset rows= "50%,50%" >
<frame name=top src= "top.html" >
<frame Name=button src= "button.html" >
</frameset>
</HTML>

On the frame top.html code, there are some refresh buttons:

The code is as follows Copy Code

<body>
<input Type=button value= "Method 1 Refresh" onclick= " Window.parent.frames[1].location.reload () "><br>
<input Type=button value=" Method 2 Refresh "onclick=" Window.parent.frames.bottom.location.reload () "><br>
<input Type=button value=" Method 3 Refresh "onclick=" window.parent.frames[' Bottom '].location.reload () ><br>
<input Type=button value= "Method 4 Refresh" onclick= " Window.parent.frames.item (1). Location.reload () "><br>
<input Type=button value=" method 5 Refresh "onclick=" Window.parent.frames.item (' Bottom '). Location.reload () "> br>
<input Type=button value=" Method 6 Refresh "onclick=" Window.parent.bottom.location.reload () "><br>
<input Type=button value=" Method 7 Refresh "onclick=" window.parent[' Bottom '].location.reload () ><br>
</body>

The next Frame bottom.html code, which is a JS window, in the frame loading, on the frame of JS is activated to demonstrate the effect of the refresh.

The code is as follows Copy Code

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

The above 7 kinds of methods you can choose one, according to your actual situation selection, compare the entire frame to refresh the JS code.
