Question

I’m trying to use jquery to detect whether an iframe fails to load or the page doesn’t exist, but the code below isn’t working:

$('#frame').error(function(){
    //code here
});

Answer 1

One of the comments on the documentation says:

Using .error() on an iframe never seems to trigger (even though
.load() will trigger on a successful iframe load).

This event does not appear to be designed to work in this use case.

The answers to this question explain how to do it.
