Dynamically set document.domain to iframe

rated 0 times [ 96] [ 4] / answers: 1 / hits: 39582 / 11 Years ago, mon, march 11, 2013, 12:00:00

I have an iframe that injects in pages, called him "helper". So due to same origin policy I need to set iframe domain the same is parent window domain. But I can't get access to parent window domain. How can it be solved?

This code is currently working for 2nd level domains:

pathArray = window.location.host.split('.');

var arrLength = pathArray.length;

var domainName = pathArray.slice(arrLength - 2, arrLength).join('.');

document.domain = domainName;

but I need to somehow get it from parent window rather than relying on 2nd level domain

I do not know if it will help but i use this in iframe

 try {

    var domainName = window.parent.parent.iframeData.domainName;

}

//Access violation

catch (err) {

    document.domain = window.location.hostname.replace('www.', '');

}

So i check if domain already set we have exception ang try to guess domain, in either case, there is no need to set a domain

EDIT:
More correctly to use post message to set domain if needed
