Ladda

A set of buttons which merge loading indicators into themselves to bridge the gap between action and feedback.

Instructions

The compiled files for the project that you should be using are available in the /dist directory. You will need to include both the ladda.min.js and spin.min.js files as well as ONE of the two style sheets. If you want the button styles used in the Ladda example page use the ladda.min.css file, if you want to have the functional buttons without the visual style (colors, padding etc) use the ladda-themeless.min.css file.

HTML

Ladda buttons must be given the class ladda-button and the button label needs to have the ladda-label class. Below is an example of a button which will use the expand-right animation style.

<button class="ladda-button" data-style="expand-right"><span class="ladda-label">Submit</span></button>

Buttons accepts three attributes:

data-style: one of the button styles, full list in demo [required]
data-color: green/red/blue/purple/mint
data-size: xs/s/l/xl, defaults to medium

JavaScript

If you will be using the loading animation for a form that is submitted to the server (always resulting in a page reload) you can use the bind() method:

// Automatically trigger the loading animation on click
Ladda.bind( 'input[type=submit]' );

// Same as the above but automatically stops after two seconds
Ladda.bind( 'input[type=submit]', { timeout: 2000 } );

If you want JavaScript control over your buttons you can use the following approach:

// Create a new instance of ladda for the specified button
var l = Ladda.create( document.querySelector( '.my-button' ) );

// Start loading
l.start();

// Will display a progress bar for 50% of the button width
l.setProgress( 0.5 );

// Stop loading
l.stop();

// Toggle between loading/not loading states
l.toggle();

// Check the current state
l.isLoading();

All loading animations on the page can be stopped by using:

Ladda.stopAll();

Module

The spinner and Ladda can be loaded as a module using either Common.js or AMD.

// Using Require.js
define(['ladda'], function(Ladda) {
	// Make Buttons Here
});

Browser support

The project is tested in Chrome and Firefox. It Should Work™ in the current stable releases of Chrome, Firefox, Safari as well as IE9 and up.
