jQuery get value of select onChange

Question

I was under the impression that I could get the value of a select input by using this:- $(this).val();

and applying the onchange parameter to the select field.

It would appear it only works if I reference the ID. How could I do this using this? 

Answer 1

Try the following lines of code-

$('select').on('change', function() { 
    alert( this.value ); 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js">
</script> <select> 
            <option value="1">One</option> 
          <option value="2">Two</option> 
</select>

You can also reference with onchange event-

function getval(sel) 
{ 
      alert(sel.value); 
}

<select onchange="getval(this);"> 
      <option value="1">One</option> 
      <option value="2">Two</option> 
</select>
