Get value from "Bootstrap-Select"

Question

I have a selectbox, and when I select a parameter, it updates the input field with selectbox values. This works with the old version of Bootstrap-Select. But in the new version, it no longer works. I am looking for a way to make this work in the new version. Thanks.

• Old version (working): http://jsfiddle.net/u967uwtf/
• Newer version (doesn't work): http://jsfiddle.net/9nzcLar6/

HTML:

<select class="selectpicker Categoria" multiple="">
  <option selected>A1</option>
  <option selected>A2</option>
  <option>A3</option>
  <option>A4</option>
</select>
<input type="text" class="ChangeCategory" name="ChangeCategory">

JS:

$('select').selectpicker();

$(".Categoria").change(function() {
  f2();
});

var f2 = function(){
  $('.ChangeCategory').val($(".Categoria").val());
}
f2();

Answer 1

One solution is to use the methods Array.from()and mapfor all selected values.

var values=Array.from($(".Categoria").find(':selected')).map(function(item){
    return $(item).text();
});

Working solution

$('select').selectpicker();

$(".Categoria").change(function() {
  f2();
});

var f2 = function(){
   var values=Array.from($(".Categoria").find(':selected')).map(function(item){
      return $(item).text();
   });
   $('.ChangeCategory').val(values);
}
f2();
