			<h1>DataTables example <span>Custom HTTP variables</span></h1>

			<div class="info">
				<p>It can often be useful to send extra information to the server when utilising DataTables'
				server-side processing option. This is done by using the <a href=
				"//datatables.net/reference/option/ajax"><code class="option" title=
				"DataTables initialisation option">ajax<span>DT</span></code></a> option's <code>data</code> parameter
				which can be used in one of two different ways:</p>

				<ul class="markdown">
					<li><code>object</code> - An object data to send to the server. This is useful for adding static
					data to the request.</li>
					<li><code>function</code> - A function which will manipulate the data object to send to the server,
					adding values as required. Using the <code>data</code> parameter as a function allows the
					additional data to evaluated and added to the request at the time the request is made.</li>
				</ul>

				<p>The example below shows server-side processing being used with an extra parameter being sent to the
				server by using the <code>ajax.data</code> option as a function.</p>
			</div>

			<table id="example" class="display" cellspacing="0" width="100%">
				<thead>
					<tr>
						<th>Name</th>
						<th>Position</th>
						<th>Office</th>
						<th>Extn.</th>
						<th>Start date</th>
						<th>Salary</th>
					</tr>
				</thead>

				<tfoot>
					<tr>
						<th>Name</th>
						<th>Position</th>
						<th>Office</th>
						<th>Extn.</th>
						<th>Start date</th>
						<th>Salary</th>
					</tr>
				</tfoot>
			</table>

			<ul class="tabs">
				<li class="active">Javascript</li>
				<li>HTML</li>
				<li>CSS</li>
				<li>Ajax</li>
				<li>Server-side script</li>
			</ul>

			<div class="tabs">
				<div class="js">
					<p>The Javascript shown below is used to initialise the table shown in this
					example:</p><code class="multiline brush: js;">$(document).ready(function() {
	$('#example').dataTable( {
		&quot;processing&quot;: true,
		&quot;serverSide&quot;: true,
		&quot;ajax&quot;: {

			&quot;data&quot;: function ( d ) {
				d.myKey = &quot;myValue&quot;;
				// d.custom = $('#myInput').val();
				// etc
			}
		}
	} );
} );</code>

					<p>In addition to the above code, the following Javascript library files are loaded for use in this
					example:</p>

					<ul>
						<li><a href="../../media/js/jquery.js">../../media/js/jquery.js</a></li>
						<li><a href="../../media/js/jquery.dataTables.js">../../media/js/jquery.dataTables.js</a></li>
					</ul>
				</div>

				<div class="table">
					<p>The HTML shown below is the raw HTML table element, before it has been enhanced by
					DataTables:</p>
				</div>

				<div class="css">
					<div>
						<p>This example uses a little bit of additional CSS beyond what is loaded from the library
						files (below), in order to correctly display the table. The additional CSS used is shown
						below:</p><code class="multiline brush: js;"></code>
					</div>

					<p>The following CSS library files are loaded for use in this example to provide the styling of the
					table:</p>

					<ul>
						<li><a href=
						"../../media/css/jquery.dataTables.css">../../media/css/jquery.dataTables.css</a></li>
					</ul>
				</div>

				<div class="ajax">
					<p>This table loads data by Ajax. The latest data that has been loaded is shown below. This data
					will update automatically as any additional data is loaded.</p>
				</div>

				<div class="php">
					<p>The script used to perform the server-side processing for this table is shown below. Please note
					that this is just an example script using PHP. Server-side processing scripts can be written in any
					language, using <a href="//datatables.net/manual/server-side">the protocol described in the
