JavaScript

Event Functions

Description

The core JavaScript library provides several functions for adding and removing events from objects.

Discussion

Many developers like to create 'clean' HTML that does not have any JavaScript events embedded in the HTML. This provides a nice separation between the HTML layout and the behavior of the HTML page.

The functions in this section describe how you can use JavaScript to attach (i.e. bind) JavaScript code to the various element events in your HTML page.

This methodology is often referred to as 'unobtrusive' JavaScript because the JavaScript which controls the HTML does not clutter up the HTML markup and is kept separate from the HTML.
