Usually I use $(\"#id\").val() to return the value of the selected option, but this time it doesn\'t work.
The selected tag has the id aioConceptName
If you are in event context, in jQuery, you can retrieve the selected option element using :
$(this).find('option:selected') like this :
$('dropdown_selector').change(function() {
//Use $option (with the "$") to see that the variable is a jQuery object
var $option = $(this).find('option:selected');
//Added with the EDIT
var value = $option.val();//to get content of "value" attrib
var text = $option.text();//to get content
});
Edit
As mentioned by PossessWithin, My answer just answer to the question : How to select selected "Option".
Next, to get the option value, use option.val().
