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"); }); 

Answer 2

var id = $(this).find('option:selected').attr('id');

then you do whatever you want with selectedIndex

I've reedited my answer ... since selectedIndex isn't a good variable to give example...
