【需求】：点击不同链接，使DataTables加载不同的数据，并定时拉取最新数据
本文适用jquery.dataTables.min.js 版本：1.9.4 ；其它几个js：
jquery-2.0.3.min.js
fnReloadAjax.js 下载
HTML
<a href="#" id="1" class="cluster">rmqdev-1</a>
<a href="#" id="2" class="cluster">rmqdev-2</a>
<table id="sample-table-2">
<thead>
<tr>
<th>#</th>
<th>Node name</th>
<th>IP</th>
<th>File descriptors</th>
<th>Socket descriptors</th>
<th>Erlang processes</th>
<th>Memory</th>
<th>disk space</th>

</table>
JS
<script type="text/javascript">
var table;
$('.cluster').click(function () {
var cluster_id = $(this).attr("id");
listNode(cluster_id);
});
jQuery(function ($) {
setInterval(function () {
if ($.fn.dataTable.fnIsDataTable(document.getElementById('sample-table-2'))) {
table.fnReloadAjax();
}
},3000);
});
function listNode(cluster_id) {
if ($.fn.dataTable.fnIsDataTable(document.getElementById('sample-table-2'))) {
table = $('#sample-table-2').DataTable();
table.fnDestroy(false);
}
table = $('#sample-table-2').DataTable( {
"bProcessing": true,"sAjaxSource": "/node/list?cluster_id=" + cluster_id
} );
}
</script>
后台返回JSON样例
