Scrollspy

What is it?

Scrollspy is something that I needed to include in a project that does not use bootstrap. I still needed the scrollspy functionality that is bundled with bootstrap and after playing around with some alternatives, I found that the best solution was to create my own. The idea was to create a simple solution that did pretty much everything that bootstraps solution offers. So this is why I created this plugin.

For those that are not familiar with bootstraps scrollspy, basically this allows you to attach the plugin to a ul styled menu on a single page application. When you scroll down the page, the pages that you pass through would then mark the li children of your menu with an active class.

Requirements

jQuery

Demo

I have created a demo which you can find here: http://codepen.io/r3plica/pen/NqbarV

Installation

unzip the contents to your desired location and include either library on your page.

How to use

It's really easy to use, simply initialise the script like this:

    $("#nav").scrollspy();

To pass options to the plugin, simply pass an object to the call like so:

    $("#nav").scrollspy({ offset: -25 });

Available options

Currently there are only a few options:

activeClass

This allows you to define your own active class that gets added to the li element of the menu. default: 'active'

animate

This tells the plugin whether it should animate the scroll when a link in your menu is click or not. default: false

duration

This is the duration of the animation in milliseconds. default: 1000

offset

This tells the plugin if there is any need to include an offset. default: 0

onChange

This function is called whenever the document scrolls into a new page.

onExit

In some cercumstances there will be a page that is not included in the menu. When scrollspy gets to this area the onExit function is called.

You can’t perform that action at this time.
