Get element text through GTM Custom JavaScript Variable

问题

I have two groups of links all with the same class names, the only difference is the text in the . I need to get the text for the clicked link and pass it to GA through GTM.

<div class="item-set">
  <header>Section Title One</header>
  <section class="products">
    <div class="list">
      <a href="/Product/60216935"><img src="/ProductImages1.jpg"></a>
    </div>
    <div class="list">
      <a href="/Product/6021693x"><img src="/ProductImages2.jpg"></a>
    </div>
    <div class="list">
      <a href="/Product/6021693y"><img src="/ProductImages3.jpg"></a>
    </div>
  </section>
</div>
<div class="item-set">
  <header>Section Title Two</header>
  <section class="products">
    <div class="list">
      <a href="/Product/60216935"><img src="/ProductImages1.jpg"></a>
    </div>
    <div class="list">
      <a href="/Product/6021693x"><img src="/ProductImages2.jpg"></a>
    </div>
    <div class="list">
      <a href="/Product/6021693y"><img src="/ProductImages3.jpg"></a>
    </div>
  </section>
</div>

I have created a custom javascript variable

function() {
  $('section.products div.list').click(function() {
    return $(this).closest('.item-set').find('header').text();
  });
}

But the bleep thing isn't working as I expect (or at all). It returns "undefined".

Any assistance is greatly appreciated.

回答1:

You shouldn't bind to click event in JS variable. You should use JS variables in GTM only for receiving values

The correct way to achieve your goal is:

1) Enable built-in variable Click Element (if you already have it, you can skip this step)

2) Create trigger, which will fire when you clicking on your links CSS selector on the screenshot is .item-set .list a

3) Create JS variable Code is: function() { return $({{Click Element}}.closest('.item-set')).find('header').text(); } 3) Create a tag, which will send data to GA Here you can use your variable form step 3 {{Click List Header}}

Maybe you are not capturing/storing the return $(this).closest('.item-set').find('header').text(); from the function?

When you for example immediately invoke your function and click a div, the text of the <header> will be logged to the console.

(function() {
    $('section.products div.list').click(function(e) {
        e.preventDefault(); // to prevent the default action of the click
        console.log($(this).closest('.item-set').find('header').text());
        return $(this).closest('.item-set').find('header').text();
    });
})();

<div class="item-set">
    <header>Section Title Two</header>
    <section class="products">
