What Is a "script" Tag/Element?

A "script" element is an optional sub-element of the "head" and many other XHTML elements. If a "script" element is placed inside the "head" element, the specified script code will not be executed immediately.

Usually, you use "script" elements in the "head" element to define script functions. and use other "script" elements in the "body" element to call those functions. Here is good example of a script element:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
 <head>
  <title>My First Script Document</title>
  <script type="text/javascript">
  function hello() {
    alert("Hello world!?");
  }
  </script>
 </head>
 <body>
  <p><script type="text/javascript">
    hello();
  </script></p>
 </body>
</html>

If you save the above document as hello.html, and view it with Internet Explorer, you will see a small dialog box showing up.
