自定义Google跟踪代码管理器JavaScript错误

Question

Trying to setup a custom JavaScript in GTM where the innerHTML value is checked for X and if it is X fires.

Here's what I have so far but it's not firing correctly

function() {
  var el = document.getElementById('ltrNumPlaceholder');
  if (el == null) return 0;
  return parseInt(el.innerHTML);
 }

I also tried this but GTM complains there there is a syntax error on a line that doesn't exist. (GTM error message for the below is: " Error at line 5, character 2: Parse error. ')' expected. ")

function(){
   var stepNum = document.getElementById('ltrNumPlaceholder').innerHTML;
   if(stepNum == 2)return parseInt(stepNum);
};

Thanks for your help in advance.

要解决此错误消息，只需在函数末尾（大括号后）删除分号即可。
