Posted Under: Angular, Bootstrap, HTML5, jQuery, jQuery Plugins, Template, Tutorials on Apr 4, 2017
Ladda a beautiful user interface approach of integrating progress indicators in HTML buttons. It give a nice user experience as it immediately gives feedback to user that his/her requested operation is underway. Ladda is available on different CDN which make its usage extremely simple, you just have to add the link to CDN and simple write the HTML for the button and you are done. Ladda buttons are highly configurable and every aspect of its design can be configured. Required files for to render Ladda Button are.
<!-- Ladda Stylesheet -->
<link rel="stylesheet" href="http://lab.hakim.se/ladda/dist/ladda.min.css" />
<!-- Ladda JavaScript -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/Ladda/1.0.0/spin.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Ladda/1.0.0/ladda.min.js"></script>
Please not the order in which the scripts are called, it should be this way otherwise it will throw an error.

Next is simple you need to add the button tag like the following
<button class="ladda-button" data-color="green" data-style="expand-left">Submit</button>
Ladda button must have a ladda-button CSS Class. Above code will render in the following button with spinner. Click on it.



A total of 12 different styles are supported for the spinner. Possible data-style values are. Click on any button to view them in action.

expand-left

expand-right

expand-up

expand-down

contract

contract-overlay

zoom-in

zoom-out

slide-left

slide-right

slide-up

slide-down

data-color attribute can only support five color options i.e green,red,blue,purple and mint. However if you want to customize it you can do so by adding the following CSS file
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/Ladda/1.0.0/ladda-themeless.min.css" />
Progress Bar can also be shown in the Ladda Buttons

expand-right

contract

Percentage of loading can be controlled via the JavaScript API
var l = Ladda.create( document.querySelector( 'button' ) );
l.start(); // Start Progress bar
l.stop(); // Stop Progress bar
l.toggle(); // Toggle Start/Stop
l.isLoading(); // Check if it is Loading
l.setProgress( 0-1 ); // Set the progress bar position 
			// 0 mean start and 1 mean full	
if the Ladda button is applied to a form the form will be submitted and the page is reloaded. To alter this behavior bind the Button with the ladda, like the following code.
// 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 } );
Ladda Buttons can be rendered in four size for that data-size attribute is used and it has xs,s,l and xl values, as demonstrated below.
<button class="ladda-button" data-color="mint" data-style="expand-right" data-size="xs">Submit</button>

Extra Small, xs
