ThinkPHP を使用してデータテーブルを統合し、サーバー側のページングを実装する方法

$('.table-sort').dataTable({
 processing: true,
  serverSide: true,
  ajax: {
   "url":"{:U('Msg/index')}",
   "data":function(d){ //额外传递的参数
    d.mintime = $('#logmin').val();
    d.maxtime = $('#logmax').val();
   }
  },
  bStateSave: true,//状态保存
  aLengthMenu : [20, 30, 50, 100, 150],
  bProcessing : true,
  bAutoWidth: false,
  bFilter : true, //是否启动过滤、搜索功能
  bInfo : true, //是否显示页脚信息，DataTables插件左下角显示记录数 
  createdRow: function ( row, data, index ) {
   $(row).addClass('text-c');
   $('#count').html(data.recordsFiltered);
  },
  aoColumns: [
   {
    "sClass": "text-center",
    "data": "id",
    "render": function (data, type, full, meta) {
     return &#39;<input type="checkbox" name="select" value="&#39; + data + &#39;" />&#39;;
    },
    "bSortable": false
   },
   { "mData": "id" },
   { "mData": "fromnickname"},
   { "mData": "content" },
   { "mData": "msgtype" },
   { "mData": "time"},
   {
    "sClass": "text-center",
    "data": "id",
    "render": function (data, type, full, meta) {
     html = &#39;<a title="查看" href="javascript:;" rel="external nofollow" rel="external nofollow" onclick="show(`查看`,`__URL__/show/id/&#39;+ data + &#39;`,``,`610`)" class="ml-5" style="text-decoration:none"><i class="Hui-iconfont">查看</i></a>&#39;;
     html += &#39;<a style="text-decoration:none" class="ml-5" onClick="signDel(this,&#39;+ data +&#39;)" href="javascript:;" rel="external nofollow" rel="external nofollow" title="删除"><i class="Hui-iconfont"></i>删除</a>&#39;;
     return html;
    },
    "bSortable": false
   }
  ]
});

控制器:
接收参数如下:
draw    前端传过来的值,原值返回,用于验证
mintime、maxtime 自定义参数(时间)
search.value  datatables搜索框参数,用于查询筛选
order.0.column  要排序的单元格(从0开始,字段需要自己设置)
order.0.dir   排序(升序、降序)
start    起始条数(第几条开始)
length    查询长度
返回的数据如下:
draw    返回前端传过来的值
recordsTotal  记录总条数
recordsFiltered  条件筛选后的记录总条数
data    服务端查询的数据
返回数据形式:json

public function index()
{
 if(IS_AJAX){
  $list = D('Msg')->getData(I('get.'));
  $this->ajaxReturn($list);
 }
 $this->display();
}

public function getData($data)
{
 //获取Datatables发送的参数 必要
 $draw = $data['draw']; //这个值直接返回给前台
 //获取时间区间
 $timeArr['mintime'] = $data['mintime'];
 $timeArr['maxtime'] = $data['maxtime'];
 $where = $this->dealTime($timeArr);
 //搜索框
 $search = trim($data['search']['value']); //获取前台传过来的过滤条件 
 if(strlen($search) > 0) {
  $where['id|fromnickname|content|msgtype'] = array('like','%'.$search.'%');
 }
 //定义查询数据总记录数sql
 $recordsTotal = $this->count();
 //定义过滤条件查询过滤后的记录数sql
 $recordsFiltered = $this->where($where)->count();
 //排序条件
 $orderArr = [1=>'id', 2=>'fromnickname', 3=>'content', 4=>'msgtype', 5=>'time'];
 //获取要排序的字段
 $orderField = (empty($orderArr[$data['order']['0']['column']])) ? 'id' : $orderArr[$data['order']['0']['column']];
 //需要空格,防止字符串连接在一块
 $order = $orderField.' '.$data['order']['0']['dir'];
 //按条件过滤找出记录
 $result = [];
 //备注:$data['start']起始条数 $data['length']查询长度
 $result = $this->field('id,fromnickname,content,msgtype,time')
     ->where($where)
     ->order($order)
     ->limit(intval($data['start']), intval($data['length']))
     ->select();
 //处理数据
 if(!empty($result)) {
  foreach ($result as $key => $value) {
   $result[$key]['time'] = date("Y-m-d H:i:s",$value['time']);
   $result[$key]['recordsFiltered'] = $recordsFiltered;
  }
 }
 //拼接要返回的数据
 $list = array(
  "draw" => intval($draw),
  "recordsTotal" => intval($recordsTotal),
  "recordsFiltered"=>intval($recordsFiltered),
  "data" => $result,
 );
 return $list;
}

1. 在WdatePicker中添加onpicked回调函数
2. 执行table.fnFilter(),其中table为datatables对象

<input type="text" onfocus="WdatePicker({maxDate:&#39;#F{ $dp.$D(\&#39;logmax\&#39;)||\&#39;%y-%M-%d\&#39;}&#39;, onpicked:function(){table.fnFilter();}})" name="mintime" id="logmin" class="input-text Wdate" style="width:120px;">

ajax: {
  "url":"{:U('Msg/index')}",
  "data":function(d){ //额外传递的参数
   d.mintime = $('#logmin').val();
   d.maxtime = $('#logmax').val();
  }
