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%"> <thead> <tr> <th>ID</th> <th>First name</th> <th>Last name</th> <th>ZIP / Post code</th> <th>Country</th> </tr> </thead> </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( { 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.
