Dreamweaver behaviors are made up of events and actions.
The event tells the action when to run.
Typical events include:
- onLoad (when page loads in browser)
- onClick (when user clicks on something)
- onMouseOver (when user movies mouse pointer over something)
- onMouseOut (when user moves mouse pointer off something)
The above are a few of the most commonly used events; others are available and sometimes useful.
When you add a behavior, Dreamweaver selects an event by default. You may need to change this; the default is not always the event you want.
Not all browsers support all events.
Most events are the result of user action. But not all: for example, a timer can send an event after a certain number of milliseconds have elapsed.
