get value from list of select-CodePudding

I have list of selection, and I need value of that option. I have coded as below:

HTML code:

  <select >
      <option value="all_section" data-id="rid0">All Section</option>
      <option value="id1" data-id="rid1">Section 1</option>
      <option value="id2" data-id="rid2">Section 2</option>
  </select>
  <select >
      <option value="all_section" data-id="rid0">All Section</option>
      <option value="id3" data-id="rid3">Section 3</option>
      <option value="id4" data-id="rid4">Section 4</option>
  </select>
  <select >
      <option value="all_section" data-id="rid0">All Section</option>
      <option value="id5" data-id="rid5">Section 5</option>
      <option value="id6" data-id="rid6">Section 6</option>
  </select>

Jquery code :

   $(document).on("change",".sectionSelect",()=>{
    let section_id = $(this).children(":selected").val();
    let room_id = [value of 'data-id' attribute of that option]
    console.log(section_id);
    console.log(room_id);
   })

Here, sectionSelect is common class for them all, I have applied on change event on them to detect change. Problem is that I'm getting this object but not able get value of that option.

And one more problem is I also need data-id attribute value of that option.

please help me

You can do it like this:

$(document).on("change", ".sectionSelect", function() {
  var selectedOption = $("option:selected", this);
  let section_id = selectedOption.val();
  let room_id = selectedOption.attr("data-id");
  console.log(section_id);
  console.log(room_id);
})

This will give you both the Id and data-id of the selected option.

demo

$(document).on("change", ".sectionSelect", function() {
  var selectedOption = $("option:selected", this);
  let section_id = selectedOption.val();
  let room_id = selectedOption.attr("data-id");
  console.log(section_id);
  console.log(room_id);
})
