This question is related to
javascript
jquery
Try this
on change event
$("#jodSel").on('change',function(){
var getValue=$(this).val();
alert(getValue);
});
Note: In dropdownlist if you want to set id,text relation from your database then, set id as value in option tag, not by adding extra id attribute inside option its not standard paractise though i did both in my answer but i prefer example 1
HTML Markup
Example 1:
<select id="example1">
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
<option value="4">four</option>
</select>
Example 2 :
<select id="example2">
<option id="1">one</option>
<option id="2">two</option>
<option id="3">three</option>
<option id="4">four</option>
</select>
Jquery:
$("#example1").on('change', function () {
alert($(this).val());
});
$("#example2").on('change', function () {
alert($(this).find('option:selected').attr('id'));
});

Try the change event and selected selector
$('#jobSel').change(function(){
var optId = $(this).find('option:selected').attr('id')
})
First set a custom attribute into your option for example nameid (you can set non-standardized attribute of an HTML element, it's allowed):
'<option nameid= "' + n.id + "' value="' + i + '">' + n.names + '</option>'
then you can easily get attribute value using jquery .attr() :
$('option:selected').attr("nameid")
For Example:
<select id="jobSel" class="longcombo" onchange="GetNameId">
<option nameid="32" value="1">test1</option>
<option nameid="67" value="1">test2</option>
<option nameid="45" value="1">test3</option>
</select>
Jquery:
function GetNameId(){
alert($('#jobSel option:selected').attr("nameid"));
}
If you are trying to get the id, then please update your code like
html += '<option id = "' + n.id + "' value="' + i + '">' + n.names + '</option>';
To retrieve id,
$('option:selected').attr("id")
To retrieve Value
$('option:selected').val()
in Javascript
var e = document.getElementById("jobSel");
var job = e.options[e.selectedIndex].value;
