jQuery get data-id from selector onchange

Question

Is it possible to get the data attribute value during an on change event?

jQuery(document).ready(function($) {
  $('.mystatus').on("change", function() {
    var value = this.value;
    alert(value);

    var myid = get the value of data-myid
    // myid should equal '123'
  });
});

<select class="mystatus" data-myid="123">
  <option value="No Status">No Status</option>
  <option selected="selected" value="Potential">Potential</option>
</select>

Yes, I know that it works on each option. I'm asking how to get it from the select definition - to the right of the class? — shanebp, May 18 '23 at 17:01
*Is it possible to get the data attribute value during an on change event?* - yes, your code does that. If you're asking something else, then please include what you're *actually* asking in the question, not as a comment or a code comment — freedomn-m, May 18 '23 at 17:04

Since the data attribute exists on the <select>, access the data atribute using: $(this).data.

$(function() {
  $('.mystatus').on('change', function() {
    var $select = $(this);
  
    var value = $select.val();
    console.log(value);

    var selectDataId = $select.data('myid');
    console.log(selectDataId);
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select class="mystatus" data-myid="123" required>
  <option value="" selected disabled>-- Choose and option --</option>
  <option value="No Status">No Status</option>
  <option value="Potential">Potential</option>
</select>
