The loading buttons
The loading buttons can be used for showing users something is happening behind the “scene”. For example, a link is loading behind while you are showing users to wait.
Similarly, a user made an AJAX call and your script is loading the data from a database server that may take some time. In the meanwhile, you can show users that “wait on”, the data for them is loading.
As Bootstrap framework has become popular incredibly, in this tutorial, I am going to show you Bootstrap based loading buttons that you may use for purposes like mentioned above.
In fact, this is quite simple to create – no further dependencies or JS file is required. I assume that you are already working with Bootstrap, so at least CSS reference of the Bootstrap framework is already established.
Creating Bootstrap default buttons as “loading”
You just need to add a reference of font-awesome.min.css, do it in the <head> section.
In the markup section, create the button with btn btn-default classes of the size as you need. Have a look at the live demo:
In the demo page, you can see the code…
The <head> section contains the references of the CSS files:
<link rel=”stylesheet” href=”http://netdna.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css”>
<link href=”//maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css” rel=”stylesheet”>
In the markup section, the buttons are created with default classes and different sizes like btn-sm, btn-lg, btn-block etc. Each button is also assigned an icon from the font-awesome.css file:
<button class="btn btn-default"><i class="fa fa-spinner fa-spin"></i> Please wait</button>
<button class="btn btn-default btn-lg"><i class="fa fa-refresh fa-spin"></i> Loading data</button>
<button class="btn btn-default btn-sm"><i class="fa fa-spinner fa-spin"></i> wait on..</button>
<button class="btn btn-default btn-xs"><i class="fa fa-circle-o-notch fa-spin"></i> Loading</button>
<button class="btn btn-default btn-block"><i class="fa fa-spinner fa-spin"></i> Please wait while data is loading</button>
Use the button size according to the text you want to show to your users.
A demo with primary button style
Same buttons and text as in above examples, except I changed the button style to use primary classes. See the output:
Only the button classes are changed from default to primary, for example:
<button class="btn btn-primary btn-block"><i class="fa fa-spinner fa-spin"></i> Please wait while data is loading</button>
A demo with success classes
See the output with the success class of Bootstrap framework for buttons:
With danger classes
And if the wait is critical, you may show the Red buttons so users must not close the app or window:
This time, I used active state of the button as well.
