<p>DataTables' server-side processing mode is a feature that naturally fits in with Scroller perfectly.
|
|
|
64 |
Server-side processing can be used to show large data sets, with the server being used to do the data
|
|
|
65 |
processing, and Scroller optimising the display of the data in a scrolling viewport.</p>
|
|
|
66 |
|
|
|
67 |
<p>When using server-side processing, Scroller will wait a small amount of time to allow the scrolling
|
|
|
68 |
to finish before requesting more data from the server (200mS by default). This prevents you from DoSing
|
|
|
69 |
your own server!</p>
|
|
|
70 |
|
|
|
71 |
<p>This example shows Scroller using server-side processing mode and 5 million rows.
|
|
|
72 |
<strong>Important</strong> This particular example uses <a href=
|
|
|
73 |
"//datatables.net/reference/option/ajax"><code class="option" title=
|
|
|
74 |
"DataTables initialisation option">ajax<span>DT</span></code></a> as a function to 'fake' the data to
|
|
|
75 |
show Scroller's ability to show large data sets. It does not have a real database behind it! You would
|
|
|
76 |
normally not use <a href="//datatables.net/reference/option/ajax"><code class="option" title=
|
|
|
77 |
"DataTables initialisation option">ajax<span>DT</span></code></a> as a function to generate data, but
|
|
|
78 |
rather as a url for where to fetch the real data!</p>
|
|
|
79 |
|
|
|
80 |
<p>In this example we also enable the <code>loadingIndicator</code> option of Scroller to show the end
|
|
|
81 |
user what is happening when they scroll passed the currently loaded data.</p>
