I need to get the values of a $ ('select [multiple]'). val () separated by a comma. For example.

HTML code:

<select id="estado" multiple>
<option selected>SP</option>
<option selected>RJ</option>
<option selected>ES</option>
<option>MG</option>
</select>

JavaScript code with jQuery:

const estados = $('#estado').val(); //Resultado: SPRJES

How to make states return to be "SP, RJ, ES" if they were selected?

You're returning everything together.

Thank you

What you need is to use the array function join .

See what's in this example: link

HTML:

<select id="estado" multiple>
<option>SP</option>
<option>RJ</option>
<option>ES</option>
<option>MG</option>
</select>

JavaScript code with your request:

const estados = $('#estado').val().join(', '); //Resultado: SP, RJ, ES
