<h1>DataTables example <span>Deferred loading of data</span></h1>
|
|
<div class="info">
|
|
<p>When using DataTables with server-side processing, the default behaviour is to have DataTables automatically make an Ajax call and load the data, removing
|
|
anything which might have already been in the table. However, this behaviour might not always be desirable when the first page of the table has already been
|
|
preloaded in the HTML (which you might do to ensure accessibility or for performance reasons).</p>
|
|
<p>This automatic Ajax call to get the first page of data can be overridden by using the <a href="//datatables.net/reference/option/deferLoading"><code class=
|
|
"option" title="DataTables initialisation option">deferLoading</code></a> initialisation property. It serves two purposes, firstly to indicate that deferred
|
|
loading is required, but also to tell DataTables how many records there are in the full table, in this case 57 (this allows the information element and pagination
|
|
to be displayed correctly).</p>
|
|
<p>In the example below, the HTML page already has the first 10 rows of data available it in, so we use <a href=
|
|
"//datatables.net/reference/option/deferLoading"><code class="option" title="DataTables initialisation option">deferLoading</code></a> to tell DataTables that this
|
|
data is available and that it should wait for user interaction (ordering, paging etc) before making an Ajax call.</p>
