My code would be like this

<select id="id_1" class="editable-input" name="name_1">

<select id="id_2" class="editable-input" name="name_2">

<select id="id_3" class="editable-input" name="name_3">

How do I know which one is being clicked and how to get the id and name of the clicked element?

PS: I want to write the code in javascript later, because I am gonna put that code to GTM variable

With Plain JS + html update:

var info = function(dd) {
  alert(dd.id + ", " + dd.name);
};

<select id="id_1" class="editable-input" name="name_1" onclick="info(this);"></select>
<select id="id_2" class="editable-input" name="name_2" onclick="info(this);"></select>
<select id="id_3" class="editable-input" name="name_3" onclick="info(this);"></select>

With Plain JS:

var info = function(dd) {
  return function() {
    alert(dd.id + ", " + dd.name);
  }
};

var dds = document.getElementsByClassName("editable-input");
for (var i = 0, l = dds.length; l > i; i++)
  dds[i].onclick = info(dds[i]);

<select id="id_1" class="editable-input" name="name_1"></select>
<select id="id_2" class="editable-input" name="name_2"></select>
<select id="id_3" class="editable-input" name="name_3"></select>

With jQuery:

$(function() {
  $('select.editable-input').on('click', function(e) {
    alert(this.id + ", " + this.name);
  });
});

<script src="https://ajax.googleapis./ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select id="id_1" class="editable-input" name="name_1"></select>
<select id="id_2" class="editable-input" name="name_2"></select>
<select id="id_3" class="editable-input" name="name_3"></select>

If you are using jQuery, you can use the following:

 $(".editable-input").on("click", function(e) {
    var sender = $(this);

    console.log(sender.prop("id"));
    //OR
    console.log(this.id);
 });

if you are using JavaScript:

 var items = document.getElementsByClassName("example"),
     currentItem;

 for(var i = items.length; i--;) {
   currentItem = items[i];
   currentItem.onclick = function(e) {
      console.log(this.id);
   };
 }

There are some ways of doing that, but the best way of doing it, is by delegating one single event to the parent of your children.

var div = document.getElementById("parent");
div.addEventListener("click", function(e) {
  var el = e.target;
  // here you can get el.id and el.name and do whatever you want
  if (el.tagName.toLowerCase() === "select")
    alert(el.id);
});

<div id="parent">
  <select id="id_1" class="editable-input" name="name_1"></select>
  <select id="id_2" class="editable-input" name="name_2"></select>
  <select id="id_3" class="editable-input" name="name_3"></select>
</div>

Doing that, you create only one event that could handle all the children you have inside the div. So, you'll use less memory, and even if you create another <select> dinamically, it would already have the event delegated to it.

Know more about event delegation.

And if you don't like that approach, you can always use the conventional one:

var sels = document.querySelecorAll(".editable-content");
for (var i = 0; i < sels.length; i++) {
  sels[i].addEventListener("click", function(e) {
    var el = e.target;
    // here you can get el.id and el.name and do whatever you want
  });
}
