在Laravel中使用DataTables插件的方法

网络
再看那柔弱的柳树吧，在寒冬余威尚盛时节，就早早苏醒过来，望着冰冻的河面，迎着凛冽的寒风，它微微察觉出一丝春意，于是，不顾一切地率先吐翠，淡淡地披起娇黄嫩绿的新装。沿河望去，枝梢间烟纱雾彀，一片生机，这情景仿佛一首动人的歌，一首热烈向往春天的歌，一首报告春的信息的歌，一首表达美好信念的歌。我在想：既然迎春花被人称作报春花，那么，柳树可不可以叫作报春树呢春来了，万千柳枝在春风中袅袅舞动。柳树是热爱春天的，春天也是热爱柳树的。

DataTables 是一个 jQuery 的表格插件，记录一下在 Laravel 中使用的常用功能和用法，比如 ajax 获取数据，自定义搜索，效果展现，选项说明等等，有一些细节记录下来方便以后查看。

Laravel 控制器方法

接受 ajax get 请求，返回数据。

dataTables 会自带一些参数过来，需要按照格式返回数据，比如分页等。见 dataTables 官方文档说明。

代码如下：

// ajax GET 获取列表数据
public function getList(Request $request)
{
  $dynamicType = $request->get('dynamic_type');
  $draw = $request->get('draw');
  $start = $request->get('start');
  $length = $request->get('length');
  $groupId = $request->get('group_id');
  $dynamicId = $request->get('dynamic_id');
  $userid = $request->get('userid');
  $isAudit = $request->get('is_audit', 0);

  if (!$dynamicType || !in_array($dynamicType, [1, 2])) {
    return response()->json(['error' => '缺少参数！']);
  }

  $builder = Dynamics::select(['id', 'userid', 'group_id', 'dynamic_id', 'dynamic_type', 'content', 'money', 'is_audit', 'audited_at'])->where('dynamic_type', $dynamicType);

  //自定义搜索
  if ($groupId) {
    $builder->where('group_id', $groupId);
  }

  if ($dynamicId) {
    $builder->where('dynamic_id', $dynamicId);
  }

  if ($userid) {
    $builder->where('userid', $userid);
  }

  if (!is_null($isAudit)) {
    $builder->where('is_audit', $isAudit);
  }

  $total = $builder->count();
  $list = $builder->orderBy('id', 'desc')->offset($start)->take($length)->get()->toArray();


  $imgInfo = [];
  $dynamicIds = $this->getDynamicIds($list);
  if ($dynamicIds) {
    $imgInfo = DynamicImage::whereIn('dynamic_id', $dynamicIds)->pluck('images', 'dynamic_id');
  }

  $fillImages = function ($item) use ($imgInfo) {
    if (isset($imgInfo[$item['dynamic_id']])) {
      $item["images"] = json_decode($imgInfo[$item['dynamic_id']]);
    } else {
      $item["images"] = [];
    }
    return $item;
  };
  $list = array_map($fillImages, $list);

  $data = [];
  $data["draw"] = $draw;
  $data["recordsTotal"] = $total;
  $data["recordsFiltered"] = $total;
  $data["data"] = $list;
  return response()->json($data);
}


// ajax GET 获取列表数据
public function getList(Request $request)
{
  $dynamicType = $request->get('dynamic_type');
  $draw = $request->get('draw');
  $start = $request->get('start');
  $length = $request->get('length');
  $groupId = $request->get('group_id');
  $dynamicId = $request->get('dynamic_id');
  $userid = $request->get('userid');
  $isAudit = $request->get('is_audit', 0);
 
  if (!$dynamicType || !in_array($dynamicType, [1, 2])) {
    return response()->json(['error' => '缺少参数！']);
  }
 
  $builder = Dynamics::select(['id', 'userid', 'group_id', 'dynamic_id', 'dynamic_type', 'content', 'money', 'is_audit', 'audited_at'])->where('dynamic_type', $dynamicType);
 
  //自定义搜索
  if ($groupId) {
    $builder->where('group_id', $groupId);
  }
 
  if ($dynamicId) {
    $builder->where('dynamic_id', $dynamicId);
  }
 
  if ($userid) {
    $builder->where('userid', $userid);
  }
 
  if (!is_null($isAudit)) {
    $builder->where('is_audit', $isAudit);
  }
 
  $total = $builder->count();
  $list = $builder->orderBy('id', 'desc')->offset($start)->take($length)->get()->toArray();
 
 
  $imgInfo = [];
  $dynamicIds = $this->getDynamicIds($list);
  if ($dynamicIds) {
    $imgInfo = DynamicImage::whereIn('dynamic_id', $dynamicIds)->pluck('images', 'dynamic_id');
  }
 
  $fillImages = function ($item) use ($imgInfo) {
    if (isset($imgInfo[$item['dynamic_id']])) {
      $item["images"] = json_decode($imgInfo[$item['dynamic_id']]);
    } else {
      $item["images"] = [];
    }
    return $item;
  };
  $list = array_map($fillImages, $list);
 
  $data = [];
  $data["draw"] = $draw;
  $data["recordsTotal"] = $total;
  $data["recordsFiltered"] = $total;
  $data["data"] = $list;
  return response()->json($data);
}

dataTables 发 ajax 请求及一些选项设置

columnDefs 用来自定义每个字段如何展现，可以封装自己的展现逻辑，也可以获取到这一行各个字段的值。

createdRow 可以改变创建每一行的行为，比如修改这一行的样式等等。

table.draw() 方法可以重新发起 ajax 请求。
