<apex:page showHeader="true" sidebar="true" title="Testing Breadcrumb">
  <zqu:Breadcrumb name="myTest" />
  <zqu:Breadcrumb name="mySecondTest" />
  <form>
    <p>
      <input type="button" id="btn-add-1" value="Add to first breadcrumb" />
      <input type="button" id="btn-add-2" value="Add to second breadcrumb" />
    </p>
    <p>
      <input type="button" id="btn-save" value="Save to LocalStorage" />
      <input type="button" id="btn-restore" value="Restore from LocalStorage" />
    </p>

  </form>
  <div id="deleted"></div>
  <script type="text/javascript">

  (function (window, document) {
    var btnFirstAdd = document.getElementById('btn-add-1');
    var btnSecondAdd = document.getElementById('btn-add-2');
    var areaDeleted = document.getElementById('deleted');
    var btnSave = document.getElementById('btn-save');
    var btnRestore = document.getElementById('btn-restore');

    // Used to generate a random string
    function makeId(length) {
      var text = '';
      var possible = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
      for (var i = 0; i < length; i++) {
        text += possible.charAt(Math.floor(Math.random() * possible.length));
      }
      return text;
    }
    // Called when one of the buttons are clicked
    function addToBreadcrumb(breadcrumbName) {
      var timeAdded = new Date();
      var text = 'Added at ' + timeAdded.getSeconds() + '"' + timeAdded.getMilliseconds();
      (if (breadcrumbName == "myTest")
        window.breadcrumbs.myTest.append(makeId(15), text, breadcrumbName);
      else
        window.breadcrumbs.mySecondTest.append(makeId(15), text);
    }
  
    // Print the received data
    function toString(data) {
      var tmp = [];
      for (var prop in data) {
        if (data.hasOwnProperty(prop))
          tmp.push(prop + ': ' + data[prop]);
      }
      return '{ ' + tmp.join('; ') + ' }';
    }

    // Add the event listener to the button
    btnFirstAdd.addEventListener('click', function () {
      addToBreadcrumb('myTest');
    }, false);
    btnSecondAdd.addEventListener('click', function () {
      addToBreadcrumb('mySecondTest')
    }, false);
 
    // Subscribe to the deletion event
    pubsubz.subscribe(Topic.BREADCRUMB_ITEM_DELETED, function (topics, data) {
      areaDeleted.innerHTML += 'Deleted: ' + toString(data) + '<br/>';
    });
    btnSave.addEventListener('click', function (e) {
      e.preventDefault();
      window.breadcrumbs.myTest.save();
    });
    btnRestore.addEventListener('click', function (e) {
      e.preventDefault();
      window.breadcrumbs.myTest.restore();
