Basics of Javascript

The following example shows how should we write the java script


< !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



< html xmlns="http://www.w3.org/1999/xhtml" lang="en">


< head>


< title>JavaScript Hello World< / title>


< meta http-equiv="content-type" content="text/html; charset=ISO-8859-1" />


< / head>


< body>


< h1 align="center">First JavaScript


< hr />


< script type="text/javascript">


document.write(" Hello Every one! ");


< / script>


< / body>


< / html>

Using the < script > element allows the browser to differentiate between what is JavaScript and what is (X)HTML markup or regular text.

If we want to show the text "Hello Every one! " then it should be shown something in this way..


< strong>


< script type="text/javascript">


document.write("Hello World from JavaScript!");


< / script>


< / strong>

but it can not be shown in this way....

< script type="text/javascript">


< strong>


document.write("Hello World from JavaScript!");


< / strong>


< / script>
