InteractionCheck.js

Use this script to check if your users have not interacted with your page after a given amount of time. You can choose what to listen for (mousemove or scroll are good examples) and then run a callback function afterwards.

Bower

bower install interactioncheck

NPM

npm install interactioncheck --save

Usage

Include interactioncheck.js in your JavaScript bundle or add it to your HTML page like this:

<script type='application/javascript' src='/path/to/interactioncheck.js'></script>

or with NPM/Browserify

var InteractionCheck = require('interactioncheck');

Create a new checker

// Listen for mousemove event
var mousemoveCheck = new InteractionCheck('mousemove', 4000, function() {
    console.log('no mousemove');
});

// Listen for scroll event
var scrollCheck = new InteractionCheck('scroll', 4000, function() {
    console.log('no scroll');
});

// Prevent from starting immediately and restarting
var touchstartCheck = new InteractionCheck('touchstart', 4000, function() {
    console.log('no touchstart');
}, false, false);
