Getting value of ID from class

How is it possible to get the value of ID from class using google tag manager?

<html>
    <body>
        <textarea id='5' class='cp _check'>sometexthere</textarea>
    </body>
<html>

Using JQuery it is possible with this:

$(".cp._check").attr("id")

Go to variables, select new, type DOM. Select CSS selector. You can then use selectors similarly to jQuery:

enter image description here

Even though there might be multiple matches for your selector GTM retrieves the value for the first occurence only.

Data Uniqueness

This can be unreliable until you cannot be sure that class cp_check is unique.

Data-attribution way

Rather change id from 5 to "form-text-field" (or whatever you want) and your desired value put into data-id:

<textarea id='form-text-field' data-id='5' class='cp _check'>sometexthere</textarea>

And then your jQuery wil looks like:

$("#form-text-field").attr("data-id")

Google Tag Manager

1) Create macro type JavaScript:

function(){
   var dat = $("#form-text-field").attr("data-id");
   return dat;
}

2) Or Create macro type DOM ELEMENT Method -> CSS Selector

  • Selector: .cp_check (in your example) #form-text-field (in this example)
  • Attr: id (in your example) data-id (in thisexample)

I guess you should use following code: $("#cp_check").attr("id")
