Access Variable from iframe

[Gernot Pfeifer]

Hello together,

I have the the following problem (since hours of Google-Search)...

I have an HTML-Page (I will call it "Mainpage")
On this Mainpage, I have an iFrame. I would now the iFrame to access
Variables on my Mainpage.

I tried the following:

On the Mainpage
[...]
testvar="Hello World";
iframename.loca tion.reload(tru e);
[...]

on the iFrame-Page
[...]
alert (parent.testvar );
alert (testvar);
alert (top.testvar);
[...]

Each time I got the window "undefined" .

Thank you very much for you help und Greetings from Germany.

Gernot

I think this may need to be:

var testvar="Hello World";

but I can't remember why. Certainly I do what you are attempting with no
problems, but my declarations are as above.

iframename.loca tion.reload(tru e);
