<desc>Set the value of each element in the set of matched elements.</desc>
<longdesc>
<p>This method is typically used to set the values of form fields. </p>
<p>Passing an array of element values allows matching <code>&lt;input type="checkbox"&gt;</code>, <code>&lt;input type="radio"&gt;</code> and <code>&lt;option&gt;</code>s inside of n <code>&lt;select multiple="multiple"&gt;</code> to be selected. In the case of <code>&lt;input type="radio"&gt;</code>s that are part of a radio group and <code>&lt;select multiple="multiple"&gt;</code> the other elements will be deselected.</p>
<p><code>val()</code> allows you to pass an array of element values. This is useful when working on a jQuery object containing elements like <code>&lt;input type="checkbox"&gt;</code>, <code>&lt;input type="radio"&gt;</code>, and <code>&lt;option&gt;</code>s inside of a <code>&lt;select&gt;</code>. In this case, the <code>input</code>s and the <code>option</code>s having a <code>value</code> that matches one of the elements of the array will be checked or selected while those having a <code>value</code> that don't match one of the elements of the array will be unchecked or unselected, depending on the type. In case of <code>&lt;input type="radio"&gt;</code>s that are part of a radio group and <code>&lt;select&gt;</code>s, any previously selected element will be deselected.</p>

<pre><code>
$( "input:text.items" ).val(function( index, value ) {
