Access function inside an iFrame

[sharapov]

How can I access function located inside an iFrame. In other words, I have a page with an iframe in it. the iframe has a function. the main page has a button. What I want to do is when user presses on the button the function inside an iframe should execute.
I tried to accesess an iframe the following way without any luck.

document.frames("myiFrame_name&quot.document.some_function();

Can anybody help?

document.getElementById("myiFrame_name").contentWindow.some_function();

May bring you more luck.

window.frames.frmiFrame.myfunctioninframe(arg0, arg1);

frmiFrame is the name of the iFrame

myfunctioninframe is the name of the function inside the iframe that accepts 2 arguments.

If you load different pages into the iframe, make sure all of them have the functions "myfunctioninframe(arg0, arg1)" declarations" Else you will get a syntax error since it cannot find the function on the page inside iframe
