patternfly/dist/js/patternfly-functions-popovers.js

This reference implementation of PatternFly is based on [Bootstrap v3](http://getbootstrap.com/). Think of PatternFly as a "skinned" version of Bootstrap with additional components and customizations.

// Util: PatternFly Popovers
// Add data-close="true" to insert close X icon
(function ($) {
  'use strict';

  $.fn.popovers = function () {
    // Initialize
    this.popover();

    // Add close icons
    this.filter('[data-close=true]').each(function (index, element) {
      var $this = $(element),
        title = $this.attr('data-original-title') + '<button type="button" class="close" aria-hidden="true"><span class="pficon pficon-close"></span></button>';

      $this.attr('data-original-title', title);
    });

    // Bind Close Icon to Toggle Display
    this.on('click', function (e) {
      var $this = $(this),
        $title = $this.next('.popover').find('.popover-title');

      // Only if data-close is true add class "x" to title for right padding
      $title.find('.close').parent('.popover-title').addClass('closable');

      // Bind x icon to close popover
      $title.find('.close').on('click', function () {
        $this.popover('hide');
      });

      // Prevent href="#" page scroll to top
      e.preventDefault();
    });

    return this;
  };
}(jQuery));
