<h1>Scroller example <span>Server-side processing (5,000,000 rows)</span></h1>
<div class="info">
<p>DataTables' server-side processing mode is a feature that naturally fits in with Scroller perfectly.
Server-side processing can be used to show large data sets, with the server being used to do the data
processing, and Scroller optimising the display of the data in a scrolling viewport.</p>
<p>When using server-side processing, Scroller will wait a small amount of time to allow the scrolling
to finish before requesting more data from the server (200mS by default). This prevents you from DoSing
your own server!</p>
<p>This example shows Scroller using server-side processing mode and 5 million rows.
<strong>Important</strong> This particular example uses <a href=
"//datatables.net/reference/option/ajax"><code class="option" title=
"DataTables initialisation option">ajax<span>DT</span></code></a> as a function to 'fake' the data to
show Scroller's ability to show large data sets. It does not have a real database behind it! You would
normally not use <a href="//datatables.net/reference/option/ajax"><code class="option" title=
"DataTables initialisation option">ajax<span>DT</span></code></a> as a function to generate data, but
rather as a url for where to fetch the real data!</p>
<p>In this example we also enable the <code>loadingIndicator</code> option of Scroller to show the end
user what is happening when they scroll passed the currently loaded data.</p>
</div>
<table id="example" class="display" cellspacing="0" width="100%">

<th>ID</th>
<th>First name</th>
<th>Last name</th>
<th>ZIP / Post code</th>
<th>Country</th>

<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( {
serverSide: true,
ordering: false,
searching: false,
ajax: function ( data, callback, settings ) {
var out = [];
for ( var i=data.start, ien=data.start+data.length ; i<ien ; i++ ) {
out.push( [ i+'-1', i+'-2', i+'-3', i+'-4', i+'-5' ] );
}
setTimeout( function () {
callback( {
draw: data.draw,
data: out,
recordsTotal: 5000000,
recordsFiltered: 5000000
} );
}, 50 );
},
dom: "rtiS",
scrollY: 200,
scroller: {
loadingIndicator: true
}
} );
} );</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>
<li><a href="../js/dataTables.scroller.js">../js/dataTables.scroller.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>
<li><a href="../css/dataTables.scroller.css">../css/dataTables.scroller.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
DataTables documentation</a>.</p>
