I’m trying to pull an html variable from an iframe which is inside another

  • 0

I’m trying to pull an html variable from an iframe which is inside another div inside the iframe.

Here is the excerpt of the code I’m using:

var myVariable = $('#iframe-id').contents().find('.variable-inside').html();

The iframe has been give an id (#iframe-id) and the variable is inside “variable-inside” which is rendered inside the iframe.

For some reason this isn’t working for me. Is there a problem with the code?

I’m aware this method can be used if both documents are on the same domain (iframe doc and other doc) but I can still use it if it’s on the same domain, just different subdomains correct? Eg: iframe doc is at lorem.example.com and other doc is at ipsum.example.com)

Any help would be great. Thanks.

    Communication across sub-domains is not allowed (Cross-Domain-Policy), I’ve read about ways to get around it but have not tested these.

    Here’s one method: http://www.tomhoppe.com/index.php/2008/03/cross-sub-domain-javascript-ajax-iframe-etc/

    The idea is to set document.domain = "yourdomain.com" on both the parent and child pages (untested).
