<p>
Binds a handler to a particular event (like click) for each matched element. Can also bind custom events.<br>
The event handler is passed an event object that you can use to prevent default behaviour. To stop both default action and event bubbling, your handler has to return false. Note that this will prevent handlers on parent elements from running but not other jQuery handlers on the same element.
</p>
<p>
In most cases, you can define your event handlers as anonymous functions (see first example). In cases where that is not possible, you can pass additional data as the second parameter (and the handler function as the third), see second example.
