Re: Accessing Nested IFrame's Parent ID and Names

[Marina]

What is the code in 'somemethod'? Which IFrame's id or name can you not
access?

How can I access an IFrame's id or name from within a child IFrame?

My application can have nested IFrames (one IFrame exists within another).

Each child IFrame needs to access its parent IFrame's javascipt methods.
However before it attempts to access the parent IFrame method it needs to
know if its parent is truley an IFrame and the correct IFrame.

I tried assigning each IFrame an ID and then having each IFrame check its

parent IFrame's ID however, I found that child IFrame can't retrieve thier
parent's IFrame ID. For example window.parent.id should return the name of
the IFrame's parent but for some reason the id is always null. The same is
true for an IFrame's name.

I also tried seing if the child's parent contains a method and then call

that method in hopes of retriving its IFrame ID, ie.

Hi Mike,

As for the get Parent Iframe id from the nested Iframe page, here are some
of my suggestions:

1. The window.parent.id won't work for this because the window.id represent
the id of the whole window object of the parent page rather than the id of
the iframe in the parent page. Do you think so?

2. I'm not sure whether there are more than one iframes in your page? if
only one iframe ,I think we can use the document.getElementByTagName script
function to get the <iframe> element reference in the parent page, for
example, the following function will get the first <iframe> tag in the
parent page and display its "id" attribute.

function showparentinfo()
{
elm = window.parent.document.getElementsByTagName("iframe")[0];
alert(elm.id);
}

Please have a try to see whether it helps. Thanks.
