jQuery get selected option value (not the text, but the attribute 'value')

Okay, I have this code:

<select name="selector" id="selector">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
</select>

And I'd like to get the value of the option selected. Example: 'Option 2' is selected, and the value of it is '2'. The '2' is the value I need to get and not 'Option 2'.

Use :selected pseudo selector on the selected options and then use the .val function to get the value of the option.

$('select[name=selector] option').filter(':selected').val()

Side note: Using filter is better then using :selected selector directly in the first query.

If inside a change handler, you could use simply this.value to get the selected option value. See demo for more options.

//ways to retrieve selected option and text outside handler
console.log('Selected option value ' + $('select option').filter(':selected').val()); 
console.log('Selected option value ' + $('select option').filter(':selected').text());

$('select').on('change', function () {
  //ways to retrieve selected option and text outside handler
  console.log('Changed option value ' + this.value);
  console.log('Changed option text ' + $(this).find('option').filter(':selected').text());
});

<select>
  <option value="1" selected>1 - Text</option>
  <option value="2">2 - Text</option>
  <option value="3">3 - Text</option>
  <option value="4">4 - Text</option>
</select>

Old answer:

Edit: As many pointed out, this does not returns the selected option value.

~~Use .val to get the value of the selected option. See below,

$('select[name=selector]').val()~~

Solution 2:

I just wanted to share my experience

For me,

$('#selectorId').val()

returned null.

I had to use

$('#selectorId option:selected').val()

Solution 3:

$('select').change(function() {
    console.log($(this).val())
});​

jsFiddle example

.val() will get the value.

Solution 4:

You need to add an id to your select. Then:
$('#selectorID').val()
