HTML.

<noscript> tag used to render HTML if JavaScript disabled in browser.

Including JavaScript in HTML page.

In head:

<html>
  <head>
    <script type="text/javascript" src="abc.js"></script>
  </head>
 ...
<html>

or alternatively just before closing body:

  <script src="abc.js"></script>
</body>
<html>

Note

HTML 5 makes type="text/javascript" unnecessary.

Inlining JavaScript in HTML code.

<html>
  <h1>Hello!<h1/>
  <script language="javascript">
    <!--
    alert("Hello!")
    document.write("sin(10) = " + Math.sin(10))
    //-->
  </script>
</html>

console.trace();
console.log(new Error().stack); // only FF

  • An XPath processor
  • A standards-compliant SAX processor
  • A simple (classic) DOM processor
  • Proxies for XML retrieval from any domain
  • Utilities for XML and application development
