Using JavaScript to generate table of contents for a webpage

Combing the DOM (Document Object Model) with JavaScript makes it easy to dynamically build the TOC. Now I only have to add extra sections and they are automatically added to the TOC. Clicking the item in the TOC will go to the section on the page.

An easy solution. Nice.

Code

[<ul id="toc"></ul>

function buildTOC() {
   // get bullet list holder
   var toc = document.getElementById("toc");

   // get all anchors on the page
   var anchors = document.anchors;
   for (var i=0; i]
[<a name="section1" class="no_style">]Section 1[</a>]
