DHTML Events (Windows CE 5.0)
Clicking a button, moving the mouse pointer over part of the Web page, selecting some text on the page — these actions all fire events, and a DHTML author can write code to run in response to the event. This particular piece of code is generally known as an event handler. The Internet Explorer event model makes it possible for every HTML element on the page to be the source for a full set of mouse and keyboard events.
The following tables show a set of common events that every HTML element generates in Internet Explorer.
Mouse events
| Mouse event generated | User action |
|---|---|
| onmouseover | Moves the mouse pointer over (enters) an element. |
| onmouseout | Moves the mouse pointer away from (exits) an element. |
| onmousedown | Presses any of the mouse buttons. |
| onmouseup | Releases any of the mouse buttons. |
| onmousemove | Moves the mouse pointer within an element. |
| onclick | Clicks the left mouse button on an element. |
| ondblclick | Double-clicks the left mouse button on an element. |
Keyboard events
| Keyboard event generated | User action |
|---|---|
| onkeypress | Presses and releases a key (full down-and-up cycle). However, if a key is held down, multiple onkeypress events are fired. |
| onkeydown | Presses a key. Only a single event is fired, even if the key is held down. |
| onkeyup | Releases a key. |
