JavaScript for Interactive Web Pages
Posted on: Sep 15, 2008

JavaScript is an object based scripting language created for developing Internet applications. We can develop server applications or client applications with JavaScript. We can also embed JavaScript code in Web pages, which are written in HTML (Hypertext Markup Language). JavaScript is an extension to HTML that helps us create more sophisticated Web pages than we ever could with HTML alone.

JavaScript is an easy-to-use programming language that can be embedded in the header of our HTML pages. It can enhance the dynamics and interactive features of our page by allowing us to perform calculations, validate forms, write interactive games, animate objects, customize graphics selections, create security passwords, Adjust the page to fit the users browser and more.

JavaScript allows us to use features like variables, loops, functions, mathematical constants and functions, and conditional statements. In addition, JavaScript has many methods, which allow us to control the browser window and environments.

As our web industry progress is rapid, one of the main things to think about when we write scripts is to make sure that they are compatible with the browsers we are targeting. JavaScript is a scripting language that you use to communicate with browsers and other applications, so it’s actually more of an interface than a programming language. However, when JavaScript is disabled many websites will become less dynamic and lose features, which contain buttons and functionality powered by Java Scripts.

Example of Embedding JavaScript in a Web page

<html>
<body>
<script type=”text/javascript”>
document.write(“My Blog!”);
</script>
</body>
</html>
