Welcome Guest!

JavaScript and AJAX

This group focuses on JavaScript, a lightweight, object-oriented scripting language and AJAX which is based on JavaScript.

About JavaScript
JavaScript ImageJavaScript is the Netscape-developed object scripting language used in millions of web pages and server applications worldwide. Netscape's JavaScript is a superset of the ECMA-262 Edition 3 (ECMAScript) standard scripting language, with only mild differences from the published standard. JavaScript is a compact, object-based scripting language for developing client and server Internet applications.

About AJAX
AJAX is a set of JavaScript libraries written in JavaScript and allows browser-server communication w/o posting the whole page back and provides an OOP model for the browser.

JavaScript Event Handler

The JavaScript event handler contains events centered around the Document Object Model (DOM). Common events include onMouseOver and onMouseOut, onFocus and onBlur, onClick and onDblClick, onChange and onSelect, onLoad and onUnload.

For example, onMouseOver and onMouseOut are frequently used with websites to change an image when your mouse moves over it. The onClick event is used to trigger code upon a mouse click.

In the following example, we use a standard image tag set to an image, change it on mouse over, then set it back on mouse out.

<img id="Image1" src="i_search.gif"
 onmouseover="document.images['Image1'].src='i_coat.gif';"
 onmouseout="document.images['Image1'].src='i_search.gif';">
