You need to have a gap between:

$('#adropdownDetails :selected').text()

---

$('#adropdownDetails:selected').text()This may not be the value you are looking for. This is a character whitespaceor a new character in a string. You can check the picture below:

var selval = $('select:selected').text();
$('pre').html('<p>'+selval+'</p>');

p{border:solid 1px grey; padding:2px;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select><option>select...</option></select>
<pre></pre>
