JavaScript is a very powerful tool in the web programmer’s belt. Not to be confused with Java, which typically runs on the server, JavaScript runs in the browser and allows you to create scripts that can control the browser experience after a web page has been retrieved from the server. This off-loads processing from the server and allows web applications to utilize some of the features associated with PC applications, such as a rich user interface and sub-second response times. This lab will introduce you to some of the capabilities of JavaScript, and help you understand how you might use JavaScript in your web applications. You will create simple scripts to validate input forms and react to browser events such as page load, button clicks, mouse movement and keystrokes. You will also see how JavaScript can be used to change the content and appearance of web pages without reloading the entire page. This will be a fun lab in which you will learn some cool and useful web programming tricks.
