substituteteacher.js (demo)

substituteteacher.js will rotate through a series of sentences, transitioning between each one.

Quick Start

substituteteacher.js is easy to use. Add the script to your page, provide a target container and call run().

Step 0: Install

Download the latest release or install from npm:

npm install substitute-teacher --save-dev

Step 1: Add the substituteteacher.min.js file

<script src="substituteteacher.min.js"></script>

Step 2: Create your container element

<div id="sub">Fallback Text</div>

Step 3: Init substituteteacher.js

var sub = new Sub([
    "A daring JavaScript library for subsitute teachers",
    "A hilarious JavaScript library for awesome taglines",
    "A svelte JavaScript library for sweet taglines",
    "A super fun and wholesome JavaScript library for sliding fun",
    "A JavaScript library for word substitution"
]).run();

API

Sub(sentences, [options])

The Sub constructor create a new instance of sub. The sentences parameter should be a list of sentence strings. Customize the instance by passing the options parameter. The example below uses all options and their defaults:

var opts = {
  containerId: "sub",
  namespace: "sub",
  interval: 5000,
  speed: 200,
  mobileWidth: null,
  verbose: false,
  random: false,
  best: true,
  clearOriginalContent: true,
};
var sub = new Sub([
    "A daring JavaScript library for subsitute teachers",
    "A hilarious JavaScript library for awesome taglines",
    "A svelte JavaScript library for sweet taglines",
    "A badass JavaScript library for sliding fun",
    "A JavaScript library for word substitution"
], opts).run();

Options

Option	Description	Defualt
containerId	Id of the injection point for HTML	"sub"
namespace	Namespace to prepend to classes used internally	"sub"
interval	Number of milliseconds between each change	5000
speed	Number of milliseconds that each step of the animation should take	200
mobileWidth	If defined, the minimum screen size at which to enable the library	null
verbose	True to enable console logging	false
random	True if the first sentence to appear should be random	false
best	True if the sentences should be ordered to minimize the number of changes performed	true
clearOriginalContent	True to empty out container and fade in the substitute teacher, false to seemlessly transition from the original content to the first item. This only works if random is false	true

run()

Starts the rotation between sentences, and attaches resize handlers (for disabling the library on small screens if mobileWidth is defined).

stop()

Stops the rotation between sentences, and remove resize handlers.
