javascript - Save source of popup window as string?

Is there a way to save the source of a popup window outside of my domain as a string, opened by:

window.open('html');

Also another way of fixing my problem would be directing the output of the popup into a string. I could use chrome's view-source: browser function and make the popup:

window.open('view-source:html');

Since I am only using this for personal use it can be only compatible with Chrome if that's the only way to do it.

I would suggest to load the document you want to open in the popup and extract it's innerHTML like this:

var popup = window.open('http://url.com');
// documentElement is the <html> element so you would get everything inside
var source = popup.document.documentElement.innerHTML;

This works on IE. I am not exactly sure what Chrome's restrictions for cross-domain popups is so you may have to check your local settings for that.
