To pass data between frames:

Assume in our frame set we have: Left, Center, Right frames.

Then in Center or Right we use: parent.Left.Var01 = 15; to change the value of Var01 in the Left frame.

To Pass data to/from a Pop-up window:

In the pop-up we use: window.opener.Var01 = 15; to change the value of Var01 in the original window.

In the original window we use: var NewWin = window.open(URL, "Child"); and then NewWinVar02 = 15.67; to change a value in the pop-up window.

WARNING The pop-up window MUST be open and ready for data before you issue the NewWin.Var02 = 15.67; line or no data will be passed!

Now, one last topic, to actually use or do something when a piece of data changes we could use a function like this in the <head> section:

thx,
was'nt exactly what I wanted, but got the idea. Was looking for a solution like window.showModalDialog(), but it does not works in netscape.

Can you suggest anything else.

You can also pass data to and from an <iframe>

Firstly, set up your iframes with a name:

Basic function calling convention, from the "top" frame:

If you put the function in the <head> section, then the form of an outside refernece is: parent.top.updateMe();. The correct form when the function is placed in an iframe (called: headerDiv) is: parent.top.frames.headerDiv.updateMe();

Reference: Unable to reference a function in another dhtml layer NS 7.0

There's is one more passing data topic that should be covered. It is passing data from a form on one page to another page. In this case the form posts the data, it gets placed in the URL and the new page looks at its URL and picks up the data. Once you have the data you can do whatever you want to it, place it into fields of a new form or whatever.

Here is the form in help266.htm:

1 Main.html // this is main page have in 2 iframes
2 leftframe.html // id is leftframe
3 rightframe.html // id is mainframe

==============================================
this code insert into "leftframe.html"
Add button and call hello function

<script language="javascript">
function hello()
{
top.frames["mainframe"].document.body.style.backgroundColor='red';
top.frames["mainframe"].document.getElementById("TITLE").value = 'HaAHAHAHAHAHAH';
}

</script>
=============================================

rightframe.html
please insert textbox the textbox id is "TITLE"
when you click on leftframe button then
right frame have change the value

I hope you have got my point its working very good
if you know about ajax you can play many script without
refresh page

Thanks Karson.

Yes, I know about Ajax and use it to do just that. However, these examples are all on the client side while Ajax is for posting/retrieving data to/from the server.
