jQuery.error() is not working for iframe.
问题 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 }); 回答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. 回答2: iframe do not trigger onerror
