Scroll Indicator

Visualize reading progress with small and simple jQuery plugin.

Online demo and instructions available at www.tymek.cz/lab/scrollindicator

Build

$> npm install $> grunt 

Basic example

$(window).load(function () {     $.scrollIndicator(); });

This will add progress bar to the top of your page. Remember to include scrollindicator.jquery.js or it's minified version in your project, as well as css style.

Usage

You can choose parent element for scroll bar:

$("#elementbyid").scrollIndicator(); 

In this case it will be helpful to include custom style. Without setting target element in this way, it will be attatched to $("body") element. (See basic example).

Options

$.scrollIndicator({delay: 333, bindResize: false}); 

Pass options object on initialization.

delay

Time in miliseconds between interaction (ex. scroll or resize event) and plugin update. Default: 100

html5

Use of progress element. Disable for CSS3 animation.
Default: false

ieSupport

Support for IE8 and IE9 browsers. Always true if HTML5 version is turned off.
Default: true

bindResize

Re-calculate values on window.resize event.
Default: true

bindDOMSubtreeModified

React to changes in DOM model. Experimental. Not recommended.
Default: false

Public methods

$("#element").data('scrollIndicator').reload();

This will re-calculate slider value. Useful for sites with dynamic content. For now there is only that one useful public method is available.
