Javascript events
An event is a user action such as the clicking of the mouse, pressing a keyboard key, moving the cursor over an element and more that can be detected by javascript. Javascript allows you to add bits of code that link the event with scripts that you want executed.
Javascript events are defined in HTML tags, just like other attributes. Events are normally used in combination with functions, which will be executed when the event occurs.
| attribute | event that triggers the script... |
|---|---|
| onclick | a single mouse click |
| ondblclick | mouse is clicked twice rapidly |
| onload | a page or an image finishes loading |
| onmouseover | the mouse is moved over a specified object such as an image |
