<h2>Pager Widget - Ajax</h2>
<h3>Flexible client-side table sorting</h3>
<a href="index.html">Back to documentation</a>
</div>
<div id="main">
<p class="tip">
<em>NOTE!</em>
</p>
<ul>
<li>
In <span class="version updated">v2.26.0</span>, a page size of "all" will be passed to the server when set; <span class="label warning">Note</span> this change may break current server methods on number of pages to return.
<br><br>
</li>
<li>This pager WIDGET <em>can not</em> be applied to the original tablesorter.</li>
<li>Do not use this widget along with the pager plugin.</li>
<li>The pager.css file also works with this pager widget.</li>
<li>This widget is still in <span class="beta">development</span> as it has not been throughly tested.</li>
<li>Extensive documentation has not been included, as all functioning is essentially identical to the pager addon, but here are some important differences:
<ul>
<li>All of the options are now set within the <code>widgetOptions</code>.</li>
<li>Most option names have only been modified by adding <code>pager_</code> as a prefix.</li>
<li>Exceptions include moving all applied css class names into a <code>pager_css</code> option and all selectors into <code>pager_selectors</code>, including the original <code>container</code> option.</li>
<li>See the Javascript code below for a full example of how to use this widget with <strong>ajax</strong>.</li>
</ul>
</li>
<li>The "ID" column has a default filter setting of ">30" and a descending sort, but neither is applied as this demo is not connected a server (just a basic JSON file).</li>
</ul>
