Accessing variables between frames

Frédéric Mayot · Dec 20, 2003

Hi,

I have an HTML page like this :

--- test.html
<html>
<body>
<form>
<iframe id="frametest" name="frametest" src="iframe.html"></iframe>
<select multiple ondblclick="alert(frametest.v);"></select>
</form>
</body>
</html>
---

and another one :

--- iframe.html
<script>var v = 2;</script>
---

I can retrieve 'v' with IE6 but not with mozilla (firebird 0.7)

Thanks.

Fred

Make sure you have
<iframe name="frametest" ...>
then access the frame as
var frame = window.frames.frametest;
then any variables as
frame.variablename
that works with IE4+, Netscape 6+, Mozilla, Opera

Sorry, but if I replace

alert(frametest.v);

with

alert(window.frames.frametest.v);

in the code I posted, it doesn't work with mozilla (it's still fine with
IE6).
typeof(window.frames.frametest) indicates 'object window', but the v
variable is unknown.
Any idea ?

I don't think that typeof ever yields 'object window'.

Make a test case and post a URL if it doesn't work

Mozilla (firebird) returned '[object Window]' on
alert(window.frames.frametest);

I've already posted my test case..., it's in my first message ;-(

Yes, but that is not the result of typeof as you claimed earlier.

Well, you got suggestions what to use to script the iframe cross
browser, use them and I am sure it works, if not you have done something
wrong but we can only find errors if you care to show your changed code.
Here is an example using my suggestion:
http://home.arcor.de/martin.honnen/javascript/200312/accessingIframeVariable.html
The variable access works with IE4+, Netscape 6+, Mozilla, Opera 7

Well, I tried your code on my local machine, and it doesn't work. I tried
with my web server and it works. I don't understand why mozilla doesn't
allow this behavior : I thought it was (like IE) only when the domains (URL)
between the frame and the parent window were different.

Thanks for your help.

"Frédéric Mayot" a ecrit :

Well, I tried your code on my local machine, and it doesn't work.

with (allmost) your original code :

--- test.html
<html>
<body>
<iframe id="frametest" name="frametest" src="iframe.html"></iframe>
<form>
<input type=button onclick="alert(parent.frametest.v);" value="To see">
</form>
</body>
</html>
---

Works fine on my Mac (system 8.6) with :
- IE 5.0
- Mozilla 1.2
- Opera 6.03
- iCab 2.95

Notice :
iframe is no more in form, because iCab doesn't love that
with other browsers it's not important
NC4.5 doesn't know iframes ... !

If both frames are loaded either from the same server or both from a
file: URL then I the example works.
What is happening "when it doesn't work on the local machine", are you
getting any error message in the JavaScript console?
