title: How to set multiple select values from string using Jquery
body: <p>I have a span Id with some values that correspond to values in multiple select box items. I want to take the values from span Id and select the corresponding items in list. </p>
  
  <pre><code>&lt;span id="test"&gt;
    1,4
  &lt;/span&gt;
  &lt;select id='multipleSelect' multiple='multiple'&gt;
    &lt;option value="1"&gt;1&lt;/option&gt;
    &lt;option value="2"&gt;2&lt;/option&gt;
    &lt;option value="3"&gt;3&lt;/option&gt;
    &lt;option value="4"&gt;4&lt;/option&gt;
    &lt;option value="5"&gt;5&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I can read the string into array but not sure how to use array to select items in multiple Select box</p>
  
  <pre><code>var test = $("#test").text();
  var testArray = test.split(',');
  </code></pre>
  
  <p>I guess if the values are known then it is easy to do something like this </p>
  
  <pre><code>$('#multipleSelect').val(['1', '2']);
  </code></pre>
  
  <p>Here is JS fiddle to illustrate the idea so far
