With a frameset links will either open in the frame they are currently in, or a named frame. But, when you have a frameset with multiple frames, sometimes it would be useful to click on a link and have two frames change.
To open two frames with one link, you need to use dynamic HTML.
The first step, however, is to set up your frames so that the DHTML will work. You have to name your frames:
<frameset rows="100,*">
<frame src="top.html" name="top">
<frame src="bottom.html" name="bottom">
</frameset>
Set Up the Link
So far, we've created two frames, the top frame called "top" and the bottom called "bottom". In the top.html page, we'll put the link that will change both frames.
Normally, when you add a link to a frame, the link will open either in the same frame that it's in, or in the frame that is named in thetargetattribute.
In your top.html page, put a link in to change the top.html to top2.html:
<a href="top2.html">This will change both frames</a>
Then you need to add the script to change the bottom frame. You do this with JavaScript and onClick.
You use the Javascript to tell the browser to change the named frame's location:
onClick='parent.bottom.location.href="bottom2.html"'.
Remember, the
bottom frame is called "bottom". If you wanted to change a frame called
"navigation" you would writeparent.navigation.location.href
The final link to change two frames at once looks like:
<a href="top2.html" onClick='parent.bottom.location.href="bottom2.html"'>This
will change both frames</a>
