I'm looking for a way to find out which field is selected with jQuery. I build a function, but it doesn't work.

HTML example

<select id="bewerbungID">
<option value="1" name="selectName">test1</option>
<option value="2" name="selectName">test2</option>
<option value="3" name="selectName">test3</option>
</select>

JS function

$('#bewerbungID select').on('change', function() {
   alert($('option[name=selectName]:checked', '#bewerbsungID').val()); 
});

Tested in jsfiddle open link

Treat select as an input field such as text. Then it has to have a value selected - show new value whenever it changes. You logic was right but jQuery selectors got a bit confusing.

Simplified your code a bit:

$('#bewerbungID').on('change', function() {
   alert($('#bewerbungID').val()); 
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="bewerbungID">
<option value="1" name="selectName">test1</option>
<option value="2" name="selectName">test2</option>
<option value="3" name="selectName">test3</option>
</select>

The issue you are having is that you are not using the selector properly.

Basic Explanation:

The selector is everything you find within the parenthesis here: $('...'). When you use # in front of the word, that means you are selecting an element that has an id of whatever is to the right of #. In your case, ... is equal to #bewerbungID so the proper code should be as follows:

$('#bewerbungID').on('change', function() {
  alert($('#bewerbungID').val());
});

$('#bewerbungID').on('change', function() {
   alert($('#bewerbsungID option:selected').val()); 
});

It should do the trick
