Menu
Because of the widget format I'm working with I have a page which has multiple iframes embedded within iframes. I won't paste the code as it's vast and unwieldy but it is essentially just this:
<html>
<head></head>
<body>
<iframe>
<html>
<head></head>
<body>
<iframe>
<html>
<head></head>
<body>
<iframe>
<html>
<head></head>
<body>
blah
</body>
</html>
</iframe>
</body>
</html>
</iframe>
</body>
</html>
</iframe>
</body>
</html>
However, there may be more - or less - iframes dependent upon the page and template I use.
I'm trying to therefore get the ID of all of the iframes in this page, from within the most-embedded iframe.
Is this possible with jQuery? I've tried a few snippets of code but had no luck:
$('iframe', window.parent.document).each(function() {
console.log($(this).attr("id"));
});
$('iframe', parent.document).each(function() {
console.log($(this).attr("id"));
});
$('iframe').each(function() {
console.log($(this).attr("id"));
});
The output of these is a single ID string - and unfortunately it's not the iframe I'm looking to control.
Thanks in advance,

This returns an iframe element which has the wanted id, and null, if the wanted id is not found.
function searchIds(wantedId) {
var idArray = [], n,
search = function (iframes) {
var n;
for (n = 0; n < iframes.length; n++) {
if (iframes[n].frames.length > 0) {
search(iframes[n].frames);
}
idArray.push(iframes[n].frameElement.id);
idArray.push(iframes[n].frameElement);
}
};
search(window.top.frames);
for (n = 0; n < idArray.length; n += 2) {
if (idArray[n] === wantedId) {
return idArray[n + 1];
}
}
return null;
}
Notice, that searchIds() can't be run before onload of the main window has been fired.

I do not believe you can reference the iframe's children directly. You will need to recursively search each iframe using it's .contents() call.
As far as I know, this will only work as long as the same-origin policy is not violated (i.e. the iframes must point to the same domain).
