Select OnChange same value twice-CodePudding

I have a selectbox which adds articles to a list with jQuery like this:

$('#articles').on('change', function(e) {
    //adds article to list
}

This works fine, but when I try to add the same article twice, the onChange method does not fire since it is selected already.

What would be the nicest way to solve this problem?

I do not want to deselect it since it shows the user which item they selected before, and the onClick function is also not working well.

You can achieve this by using a click event on the option tag.

$('#articles').on('click', 'option', function(e) {
    //adds article to list
    console.log($(this).val());
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="articles">
<option>option 1</option>
<option>option 2</option>
<option>option 3</option>
<option>option 4</option>
<option>option 5</option>
</select>

The event will be called every time you click an option or change an option and then you can to add it to the array as before.

Using the select2 plugin it is possible to use:

  $('#articles').on('select2:close', function(e) {
      ...
  }

This will fire the function, even if it is selected already.

Thanks to: @Pete for the answer in the comments

Use select2()

$('#articles').select2().on('click', function() {
    console.log('selected : ', $(this).val());
});

$('#articles').select2().on('click', function() {
  console.log('selected : ', $(this).val());
});

</select>
