Prevent default behaviour of event in JQuery

This tutorial describes how to prevent a default behaviour of an event in JQuery.

Preventing default event

When you attach an function to an event in JQuery, you often want the default behaviour of that event to be totally overwritten. In order to do that, you can call the preventDefault() method on the event object.

For example, if you create a custom validation for your form, you don't want it to be submitted if there are any validation errors.
$('#myForm').submit(function(e) {
// do some stuff
// ...

// prevent the form from being submitted
