Ladda

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

Check out the demo page.

Instructions

Make sure the files in /dist (ladda.min.css, ladda.min.js and spin.min.js) are all included on your page.

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.
