I have a iframe embeded in my page. I saw an paper icon with sad face in it.

enter image description here

I inspect it, it has an id #sub-frame-error-details

iFrame

<iframe id="iframe-rm" name="my-iframe" src="https://192.237.175.25:555/" width="100%" height="800px" class=""></iframe>

Try #1

console.log($('#sub-frame-error-details').length);

I kept getting 0.

Try #2

document.getElementById("sub-frame-error-details")

I got null

Try #3

var obj = $("#iframe-rm").contents().find("#main-frame-error");

console.log(obj.length);

still get 0 print out.

How do I detect if it's there ?

  • I tried `var obj = $("#iframe-rm").contents().find("#main-frame-error"); console.log(obj.length);` , and I still getting `0` - while knowing for sure that it is there. – code-8 May 16 '16 at 18:59
  • Are the contents of the iframe cross-domain? If so, you can't access their contents and it will give you either a 0 or a null return depending on the way you try to access it. – JoeL May 16 '16 at 19:28

  • Yes, they're cross domain. So how would go above and detect something like that ? Is it impossible ? Please advise. – code-8 May 16 '16 at 19:29
