Select2：显示多个选定的值

Question

与此FIDDLE类似，您将如何显示多个选定的加载值？

<select multiple> 
    <option value="1">One</option> 
    <option value="2">Two</option> 
    <option value="3">Three</option> 
    <option value="4">Four</option> 
</select> 


$('select').select2().select2('val','3') 

FIDDLE

需要显示一些类似的负载

Answer 1

请选择要多个然后传递值作为数组

$('select').select2().select2('val', ['3', '1'])

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/3.3.0/select2.css" rel="stylesheet" /> 
 
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/3.3.0/select2.js"></script> 
 
<select multiple="multiple" style="width:300px"> 
 
    <option value="1">One</option> 
 
    <option value="2">Two</option> 
 
    <option value="3">Three</option> 
 
    <option value="4">Four</option> 
 
</select>

后4.1

$('select').select2().val(['3', '2']).trigger('change')

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.js"></script> 
 
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.css" rel="stylesheet" /> 
 
<select multiple="multiple" style="width:300px"> 
 
    <option value="1">One</option> 
 
    <option value="2">Two</option> 
 
    <option value="3">Three</option> 
 
    <option value="4">Four</option>
