Detect iframe

markfw · March 20th, 2011, 03:26 PM

Hi
I really don't know where to post this question but I believe is related to JavaScript (Prove me wrong)

Question:
Let say my website is www.site.com. another website (www.example.com) uses iframe tag to load my website in their iframe using src="www.site.com"

Now, how can I detect from www.site.com that www.example.com trying to load my website from iframe tag.

possibly javascript code can handle that or I need to modify the configuration of my web server which is apache.

Thanks
Mark

Hi,

the general idea would be to inspect the window.top.location and then either try to redirect this (often not possible because of cross-browser scripting security) or prevent it from displaying your site.

The following script is not mine, but from the blog of Pawal Sumata (http://www.suwala.eu/blog/2011/02/04...parent-window/) and should do the trick:

Code:

<script type="text/javascript" >
    if (window.top !== window.self) {
        document.write = "";
        window.top.location = window.self.location; 
		setTimeout(function(){
            document.body.innerHTML='';
        },1);
        window.self.onload=function(evt){
            document.body.innerHTML='';
        };
    }
</script>

Hope this helps
