Question

I need to write code that puts all of the href links from a webpage into an array. Here’s what I have so far:

var array = [];
var links = document.links;
for(var i=0; i<links.length; i++) {
  array.push(links[i].href);
}

However, this does not work on a page like Gmail’s inbox, because the some of the links are within an iframe. How can I get ALL of the links, including the ones inside the iframe?

Also, this is for a google chrome extension. In the manifest, I have all_frames set to true – does this make a difference?

Thanks

I have a method I use to access data in an IFrame. How fun that the answer is never just written down to read and use :P.
Feel free to modify and abuse:

public HtmlElementCollection GetIFrameElements(String tmpTag, int Frame)
    {
        HtmlElementCollection tmpCollection = mWebBrowser.Document.Window.Frames[Frame].Document.Body.GetElementsByTagName(tmpTag);
        return tmpCollection;
    }

I then use it to look for whatever element Im after:

foreach (HtmlElement el in GetElements("input"))
        {
            if (el.GetAttribute("id").Equals("hasNoGoogleAccount"))
            {
                el.InvokeMember("click");
            }
        }

You could always change the method to loop through and get all iFrames etc blah blah but that should be enough to get you moving.
