Google Tag Manager - Primary Expression Expected

问题

Following is my code:

<script>
    <button type = "button"
    onclick="sce.event('mw_button_click', {
    ...});>
    </button>
</script>

And when i try to enter the debug mode in Google Tag Manager I have an error:

Error in line 2 character 4: Pare error. Primary expression expected.

Does anyone know how to fix it and can help me?

If you use the button tag inside the script tag it doesn't work in GTM .Instead you should use Javascript or Jquery like I mentioned below

The below is an example from https://www.w3schools.com/jsref/event_onclick.asp . Hope this helps

// Get the button, and when the user clicks on it, execute myFunction document.getElementById("myBtn").onclick = function() {myFunction()};

/* myFunction toggles between adding and removing the show class, which is used to hide and show the dropdown content */

function myFunction() {
  document.getElementById("myDropdown").classList.toggle("show");
}

I think you need to put your onclick event into a function of its own.

Like this:

<script>
  function myEvent() {
    ...do code
  }

  <button 
    type = "button"
    onclick="myEvent('mw_button_click')">
  </button>
</script>
