JQuery docs says the .submit () event does not bubble in IE. What does it mean?

Question

From the jQuery documentation for .submit() :

JavaScript send event does not bubble in Internet Explorer. However, scripts that rely on delegating events with a send event will work sequentially in browsers with jQuery 1.4, which normalizes the behavior of the event.

What does it mean?

Answer 1

What this means is that jQuery imitated the process of submit bubbles to make it appear bubbling in browsers that don't support it. In fact, they write code to make it look bubbling. The same goes for focus and blur events. If you want to use them for delegation, use the normalized focusin and focusout .
