Change menu items out of an iframe

does anybody know how to change menu items out of an iframe?

I have one single page containing the menu and two iframes. I want to change some menu items when a certain page is loaded in one of these iframes.

I'm using the following custom function to change items - it works if used directly in the main page ...

function mm_changeItemProperty(menuName, itemName, codeRef, newValue, updateDisplay) {

  menuName = menuName.toLowerCase();

  for (i=0; i<_mi.length; i++)

    if (_mi[i][1].replace(/\&nbsp\;/ig,' ') == itemName && _m[_mi[i][0]][1] == menuName) break;

  if (i == _mi.length) return;

  _mi[i][codeRef] = newValue;

  if (updateDisplay) BDMenu(_mi[i][0]);


Thanks for help!

So, if I understand correctly: The mm_changeItemProperty() function is defined in the main page and the menu that you want to change is also in the main page, but you want to call mm_changeItemProperty() from a page that's loaded into an iframe. Correct?

Assuming that the <iframe> is defined within the main page, then you should be able to call the function by prepending parent. to the function name. Like so:


You're telling the browser, "go to the parent page and run the function named mm_changeItemProperty() contained within that page." Function parameters are passed as usual, but if you pass a variable, then you are passing the value of the variable in the iframe page, not in the parent page.

Hope that made sense, and hope it helps.

That's it - of course! :oops:

Thanks, Kevin!
