dom - Get the selected option id with jQuery

Question

I'm trying to use jQuery to make an ajax request based on a selected option.

Is there a simple way to retrieve the selected option id (e.g. "id2") using jQuery?

<select id="my_select">
   <option value="o1" id="id1">Option1</option>
   <option value="o2" id="id2">Option2</option>
</select>


$("#my_select").change(function() {
    //do something with the id of the selected option
});

Answer 1

You can get it using the :selected selector, like this:

$("#my_select").change(function() {
  var id = $(this).children(":selected").attr("id");
});
