Most browsers today understand JavaScript. JavaScript is a client side programming language that you can use to enhance your web pages and to enable your web pages to interact with your visitors.

Unlike server side programming languages such as ASP, ASP.NET, PHP, JSP, and ColdFusion which run on the computer that stores your web pages, JavaScript is run by the browser on the computer that your visitor is using to view your page. This means that the individual visitors have a choice whether the JavaScript will run. Of course running JavaScript can't do them any harm and if they don't run them they miss out on all of the nice features that you have added to your site that require JavaScript. That is their choice but they are still likely to blame you if your pages don't work because they have JavaScript turned off so make sure you tell them.

The pages in this section tell you about JavaScript and what you can do with it. There are pages that show you how to create JavaScript to perform certain functions and even complete JavaScript that you can plug straight into your page.

Many of the pages in this section contain working examples that show you how the JavaScript code discussed on the page actually function. Of course these will only work if you are viewing the pages with JavaScript enabled in your browser.

Over the years I have produced many different versions of some of my scripts that have been published on a number of different sites. This list of all my scripts will help you to find the latest version of each of the scripts.
