Get current URL from IFRAME 3 answers

I need to get notified whenever a user clicks a link on a page in an iframe that is not from the same domain. I'm aware of xss restrictions, however all i need to know is the current page being served in the Iframe. Is there a way to do this without violating xss rules?

回答1:

If not for cross-site scripting restrictions this should work. Unfortunately I don't know of a way to get the URL without violating these restrictions.

<html>
    <head>
        <script type="text/javascript">
            function GetIFrameUrl()
            {
                alert('url = ' + document.frames['frame1'].location.href);
            }
        </script>
    </head>
    <body>
        <a href="#" onclick="GetIFrameUrl();">Find the iFrame URL</a>
        <iframe name="frame1" src="http://www.google.com" width="100%" height="400"></iframe>
    </body>
</html>

回答2:

To get the iframe location using jQuery:

alert( $('iframeId').contents().get(0).location.href );

回答3:

You can easily do it with vanilla js.

Query the document for an element with the specific name, id, class or whatever

Get the source for attribute for that element

 //Get by Id
 var frame_src = document.getElementById('myIframe').src
 //Get by tag name - get the first
 var frame_src = document.getElementsByName('frmExternal')[0].src
 //Alert 
 alert(frame_src)

  <script type="text/javascript"> // if window open in iframe then redirect to main site
         if(window.top.location != window.self.location)
         {
            alert(window.self.location);
            // top.window.location.href = window.self.location;
         }
    </script>
