 <p>You use the <a href="http://api.jquery.com/jQuery.ajax/" rel="nofollow"><code>data</code></a> parameter in the options hash:</p> <blockquote> <p>Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests. See processData option to prevent this automatic processing. Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key based on the value of the traditional setting (described below).</p> </blockquote> <p>For example:</p> <pre><code>$.ajax({ url: '/pancakes/house', data: { 'where': [ 'is' ] }, // ... }); </code></pre>
