Javascript: Event Handlers
Event Handlers are the way that external actions are communicated to your script. An action by the user of the browser on the page triggers an event handler associated with the specific element on the page which was acted upon. For instance, an event is triggered every time the user rolls the mouse over an <A></A> tag on the script.
The following are the event handlers used in Javascript. Note that not all of these event handlers are available for every element on the page.
| Event | Action It Corresponds To |
| onAbort | The user aborted loading of the page |
| onBlur | the object was left: ie. the user moved the mouse off the object on the page, or thewindow was placed behind other windows |
| onChange | The user changed the object |
| onClick | the user click the mouse on the object |
| onError | the script had an error during execution |
| onFocus | opposite of onBlur, the user made an object active |
| onLoad | the page or other object finished loading |
| onMouseover | the mouse was moved over the object |
| onMouseout | the mouse was moved off an object |
| onSelect | the user selected the contecnts of the object |
| onUnload | the user left the window |
| onSubmit | the user submitted a form |
