页面向后台传数据：

"aLengthMenu": [
[5, 15, 20, -1],
[5, 15, 20, "全部"] // change per page values here
],
// set the initial value
bPaginate : true, // 是否分页，默认为 true，分页
bLengthChange : true, // 是否允许用户通过一个下拉列表来选择分页后每页的行数。行数为 10，25，50，100。这个设置需要 bPaginate 支持。默认为 true。
"iDisplayLength": 10,
"bProcessing": true,
"sAjaxSource" : "../../appcontroller/applist.json?currpage=1&pagesize=10",

后台解数据：
$aoData = $_GET[‘aoData‘];
$sEcho = 1;
$iDisplayStart = 0; <span style="white-space:pre"> </span>// 开始下标
$iDisplayLength = 10; <span style="font-family: Arial, Helvetica, sans-serif;">// 每页记录数（这两个参数是从前台传过来的，用作分页查询）</span>
if($aoData) {
$aoDataJson = json_decode($aoData);
foreach($aoDataJson as $value) {
$nameKey = $value->name;
$valueKey = $value->value;
if($nameKey == "sEcho") {
$sEcho = $valueKey;
} elseif($nameKey == "iDisplayStart") {
$iDisplayStart = $valueKey;
} elseif($nameKey == "iDisplayLength") {
$iDisplayLength = $valueKey;
}
}
}
$title = $_GET[‘title‘];
$is_offline = $_GET[‘is_offline‘];
$state = $_GET[‘state‘];
$pagesize = $iDisplayLength and $iDisplayLength or $_GET[‘pagesize‘];
$currpage =$sEcho and $sEcho or $_GET[‘currpage‘];
! $pagesize && $pagesize = 12;
! $currpage && $currpage = 1;
$condition = array();
$title && $condition[‘title‘] = $title;
$is_offline && $condition[‘is_offline‘] = $is_offline;
$state && $condition[‘state‘] = $state;
$pagesize && $condition[‘pagesize‘] = $pagesize;
$currpage && $condition[‘currpage‘] = $currpage;
$service = $this->App_model->findListApp($condition);
$service[‘returncode‘] = ‘000000‘;
$service[‘iTotalRecords‘] = 3; // 总记录数
$service[‘iTotalDisplayRecords‘] = 30; // 当前页包含的记录数（这两个是必须返回的）
return $service;
