Ladda

Buttons with built-in loading indicators, effectively bridging the gap between action and feedback.

Check out the demo page.

Instructions

Release downloads and change history is available here https://github.com/hakimel/Ladda/releases.

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. The ladda-label will be automatically created if it does not exist in the DOM. 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 accept the following 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
  • data-spinner-size: 40, pixel dimensions of spinner, defaults to dynamic size based on the button height
  • data-spinner-color: A hex code or any named CSS color.
  • data-spinner-lines: 12, the number of lines the for the spinner, defaults to 12

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( 'button[type=submit]' );

// Same as the above but automatically stops after two seconds
Ladda.bind( 'button[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();

// Delete the button's ladda instance
l.remove();

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

Ladda.stopAll();

With jQuery

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 ladda('bind') method:

// Automatically trigger the loading animation on click
$( 'button[type=submit]' ).ladda( 'bind' );

// Same as the above but automatically stops after two seconds
$( 'button[type=submit]' ).ladda( 'bind', { 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 = $( '.my-button' ).ladda();

// Start loading
l.ladda( 'start' );

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

// Stop loading
l.ladda( 'stop' );

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

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

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

$.ladda( 'stopAll' );

Module

You can bower install ladda or npm install ladda. The spinner and Ladda can be loaded as a module using AMD.

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

Or in Common.js, you will:

var ladda = require('ladda');

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.
