Is window.frameElement (for same-origin iframes) supported across all browsers?

iframe, internet-explorer, javascript, safari, webkit

Solution

I happened to look for the same information. Here's what I have found.

https://developer.mozilla.org/en-US/docs/Web/API/Window.frameElement

I have tested some browsers in addition to the MDN doc, and confirmed that it is supported by IE7+, Safari, Firefox, Chrome. So pretty much all browsers.

I haven't tested on IE6-, but I guess you don't need to care.

Problem

I have googled as much as I can and I'm not sure of the support for the document of an iframe getting the id of itself in the parent window: `window.frameElement.id`. There are so many browsers that it's hard to test them all and nothing online seems to have any information. I'm specifically wondering about: Safari iOS Safari Windows Phone IE IE 7, 8, 9, 10, 11 (I tested Firefox and Chrome and they both worked). EXAMPLE IFRAME CONTENT ``` <!DOCTYPE HTML> <html> <head></head> <body> <script type="text/javascript"> var owner = window.frameElement; var thisIsWhoIsCalling = ( owner !== null ) ? owner.id : null; window.parent.SomeJavaScriptObject.someFunction( thisIsWhoIsCalling ); </script> </body> </html> ```
