GA 事件跟踪 - 代码未触发

Question

我正在尝试创建一个新事件并开始在 GA 上跟踪它。 但是，到目前为止，我没有看到任何点击，这意味着在单击具有 class 名称 entity-signpost.component 的元素时不会触发标签。

此外，我想跟踪用户在单击事件 label 时被定向到的页面的 URL。 似乎这也有问题。

//Create new event on GA for the element with class name entity-signpost.component

//Get reference to xxyy, zzyy components
//it contains the class name entity-signpost.component
var recordingClicks = document.getElementsByClassName("entity-signpost.component")

//Adds a listener for the "click" event
recordingClicks.addEventListener('click', function handleOutboundLinkClicks (unload) {

    //Prevents the browser from going to the specific property page
    //and thus unloading the current page.
    unload.preventDefault();
    
  // Sends the event to Google Analytics category: about us, action: property link clicks, label: href and
  // redirect once the hit is done.
  ga('send', 'event', 'About Us', 'Property Link Clicks', unload.target.href, {
    hitCallback: function() {
      recordingClicks.click();
    }
  });
});
