Generate A Hierarchical Table Of Contents With Vanilla JS – toc-plugin

Description:

A vanilla JavaScript TOC plugin used to generate a list based hierarchical table of contents for long web content.

The plugin looks for heading elements within the document and generates a TOC navigation using nested HTML lists.

How to use it:

Create a container to place the table of contents.

<div data-toc></div>

Insert the ‘toc-script.js’ script into the html document.

<script src="js/toc-script.js"></script>

Generate a table of content inside the placeholder element.

myPlugin.init()

Customize the heading elements to look for.

myPlugin.init({
  selectorHeaders: 'h2, h3, h4, h5, h6'
})

Set the selector of the placeholder element.

myPlugin.init({
  selectorTocs: '[data-toc]'
})

Set the CSS class appended to the table of contents.

myPlugin.init({
  initClass: 'js-toc'
})
