ajax_loadmask.js

// General loadmasking for all ajax controls using jquery loadmask
// Prevents double requests and gives users better feedback ('Did i click that properly?'), especially on touch devices.
// On ajaxBefore (which equates to onclick in most cases) a mask will render over the target element
// On ajaxComplete the mask is destroyed.
// requires jquery.loadmask.js  (@ https://code.google.com/p/jquery-loadmask/)

$(document).on('ajaxBefore', function(event, request) {
  return $(event.target).mask('loading...');
}).on('ajaxComplete', function(event, request) {
  return $(event.target).unmask();
