jquery - How can i take the value of the specific option? -


i have code : 

function select(cities, country) {     $('<div class="btn-group "><button type="button" id="forecast"      data- toggle="modal" data-target="#mymodal" name="forecast"      class="btn btn-primary  pull-right" >show me forecast</div>').insertafter('.btn-group');     $('#cities').html(' <label for="cities">select city</label>     <select name="cities" id="city" class="form-control">' +         '<option disabled selected value> -- select option -- </option>' +           cities.map(function (city) {               return '<option value="' + city + '">' + city + '</option> ';           }).join('') + '</select>'     );     var city = $("#city option:selected").val();     console.log(city); }

i want take specific value of above select element every single moment takes first value , stores city variable

i think wanted results in demo:

select(['city1', 'city2', 'city3'], 'country1');    function select(cities, country) {      $('<div class="btn-group "><button type="button" id="forecast" data- toggle="modal" data-target="#mymodal" name="forecast" class="btn btn-primary  pull-right" >show me forecast</div>').insertafter('.btn-group');          $('#cities').html(' <label for="cities">select city</label><select name="cities" id="city" class="form-control">' +          '<option disabled selected value> -- select option -- </option>' +          cities.map(function(city) {              return '<option value="' + city + '">' + city + '</option> ';          }).join('') + '</select>'      );            var city = $('#city option:selected').val();      console.log(city) // selected city (none)      $("#city").on('change', function() {          city = $(this).find('option:selected').val();          console.log(city); // changed option new selected city      });  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div id="cities">  </div>  <div class="btn-group">  </div>
