Iframe doesn't stop to loading

Question

As answered in this post, I'm trying to set an Iframe's content with :

document.getElementById("iframe").contentDocument.write("Test123");

The problem is that even though everything seems to work (the Iframe is displaying Test123), the browser doesn't stop loading. Indeed, in Firefox's tab it's written "Connecting ..." with the spinner indicating it's still loading.

Why does it happen ? Is there a better solution to set an Iframe's content ?

Answer 1

You need to close the iframe connection:

document.getElementById("iframe").contentDocument.close();

I think that this will work.
