You need to give the iframe a "name" and use that name in the a tag "target"

I gave the name as "display" for the iframe and assigned the same to the target, but still no use any idea?

If your html is exactly as posted it is invalid, you are missing a closing quote on the "style" attribute

<iframe src="buttons.html" style="border:2px solid red; height:600px;width:300px; name="btn_frame"></iframe>

should be

<iframe src="buttons.html" style="border:2px solid red; height:600px;width:300px;" name="btn_frame"></iframe>

I changed the same, but the same problem persists.

Well it works ok for me. Try the demo on w3schools, if that doesn't work it is a problem in your browser, if it does work then there is still some other issue in your code, maybe code you haven't posted.

You need to realize that an <iframe> is effectively a separate page from the page it is on - it can even have elements with the same ID's as the parent page and they will not be confused.

Now - if you have two iframe's on the same page - for normal interactions they don't know anything about each other. What they do have in common is the same parent.

So - for one frame to contact the other you must go through the parent. From the parent you can, for example, change the source of the other iframe.

Here's a references for you - to give you the idea if I wasn't clear enough:

I found the solution by myself, thanks

for your comments. The real solution is we should use the "id" tag instead of "name" and that worked fine. May be this will be useful for the beginners like me.
