添加onclick（）链接到Drupal 7

Question

I'm working in adding an onclick attribute to a few links on my drupal 7 site. I added the menu_attributes module to assign an id to my links, tried adding the following code to a new js file I included in sites/themes/themeName.info .

function() {
  var link = document.getElementById('conversion');
  //link.setAttribute("target", "_blank");
  link.addEventListener("click", function(e){
        return gtag_report_conversion('http://www.mysite/page’); }); }

It's not adding onclick, would greatly appreciate any help.

Answer 1

Check whether the script is loading in the page. See this for the details of adding javascript in drupal 7.

Answer 2

Based on JavaScript that executes after page load and adjusted for this specific problem this code works if placed inside head

function addClick(){
                    alert('click'); //confirm it works
                    return gtag_report_conversion('http://mySite/myPage');
                }

                 //make sure this runs after dom is loaded.. so element can be found
                 document.addEventListener("DOMContentLoaded", function(){
                    var link = document.getElementById("cteconversion");
                    link.onclick=addClick;
                 });
