title: JQuery set dropdown list box selected option - not by value, but by display text
body: <p>This has probably been answered, but I am unable to find the answered question anywhere...</p>
  
  <p>Assuming we have the following HTML...</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
      &lt;head&gt;
          &lt;meta charset="UTF-8"&gt;
          &lt;title&gt;Dropdown Test&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;select name="myDropDownListName" id="myDropDownListID" class="dropdown"&gt;
              &lt;option selected="selected" value="0"&gt;Please select a value...&lt;/option&gt;
              &lt;option value="1"&gt;My Custom Value 1&lt;/option&gt;
              &lt;option value="2"&gt;My Custom Value 2&lt;/option&gt;
              &lt;option value="3"&gt;My Custom Value 3&lt;/option&gt;
          &lt;/select&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>What would the JQuery command look like to set 'My Custom value 2' to be the currently selected option in the dropdown list box, assuming I do not know the index 'value' value, and can only identify the item by the text 'My Custom Value 2'?</p>
