"Busy Button" with APEX5, jQuery and Font Awesome

Both jQuery and Font Awesome are standard included with APEX5 (still in early adopter). With a little bit of jQuery you can create an animated button that reflects that it is doing something in the background.
For this example I created a button "Text + Icon button". Simply drag and drop this in the Page Designer.
The Icon CSS Class: "fa-play-circle-o"
and the action: "Defined by Dynamic Action"
For the Dynamic Action: it should respond to the button click (of course)
Choose: Execute Javascript and enter:

$(this.triggeringElement).prop('disabled', true)
                         .children('span')
                         .toggleClass('fa-repeat')
                         .toggleClass('fa-spin')
                         .toggleClass('fa-play-circle-o')
                         ;

Add another TRUE action to the Dynamic Action, for my example I'll use "Execute Javascript" and enter:

alert ('You clicked the button, now it looks busy');

The third TRUE action for the Dynamic Action, also "Execute Javascript" will reset the button to the way it was:

$(this.triggeringElement).prop('disabled', false)
                         .children('span')
                         .toggleClass('fa-repeat')
                         .toggleClass('fa-spin')
                         .toggleClass('fa-play-circle-o')
                         ;
