如何使用数据表实现 Daterangepicker？

Question

我需要根据业务需求将此日期范围选择器与我的数据表一起使用。虽然，可以在这里看到我的日期范围排序和搜索的典型用法。 https://jsfiddle.net/zy914ko6/

我需要有关如何生成最小值和最大值以使实现适合绘制表格所需的 jQuery 脚本的帮助。 FMI：我在生产中使用服务器端 ajax 和 json。到目前为止，我的桌子正在运行，我确实获得了平局，但它没有反映“生效日期 [3]”列。

我的“有点”工作应用程序可以在这里查看
http://live.datatables.net/pexopupu/1/edit]1

在这里可以看到我用于日期范围选择器的代码示例：

var table_1 = $('table.display#tb_posts').DataTable({
   "processing": true,
   "serverSide": true,
   "ajax" : {
      "url" : "{{ route('posts.list') }}",
      "type" : "GET"
   },
   "columns": [
      {data: 'check', name:'id', className: 'text-center' },
      {data: 'DT_Row_Index', name:'DT_Row_Index', className: 'text-right' },
      {data: 'id', name: 'posts.id', className: 'text-right' },
      {data: 'title', name: 'posts.title'},
      {data: 'username', name: 'users.username'},
      {data: 'created_at', name: 'posts.created_at'},
   ],
   "autoWidth": true,
   "order": [[ 3, 'asc' ]],
   "sDom": "B<<'span8'f>r>t<<'col-sm-4'i><'col-sm-8'p>>",
   "pagination": true,
   "pagingType": "full_numbers"
});
//DateRangePicker
var startdate;
var enddate;
$('#reportrange').daterangepicker({
   locale: { format: 'DD/MM/YYYY' },
   ranges: {
      'All dates' : [moment().subtract(10, 'year'), moment().add(10, 'year')],
      'Today': [moment(), moment()],
      'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],
      '7 last days': [moment().subtract(6, 'days'), moment()],
      '30 last days': [moment().subtract(29, 'days'), moment()],
      'This month': [moment().startOf('month'), moment().endOf('month')],
      'Last month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')]
   },
   "opens": "left",
   "applyClass": "btn-primary",
   "showDropdowns": true,
},
function (start, end, label) {
   var s = moment(start.toISOString());
   var e = moment(end.toISOString());
   startdate = s.format("YYYY-MM-DD");
   enddate = e.format("YYYY-MM-DD");
});
//Filter the datatable on the datepicker apply event
$('#reportrange').on('apply.daterangepicker', function (ev, picker) {
   startdate = picker.startDate.format('YYYY-MM-DD');
   enddate = picker.endDate.format('YYYY-MM-DD');
$.fn.dataTableExt.afnFiltering.push(
function (oSettings, aData, iDataIndex) {
   if (startdate != undefined) {
      var coldate = aData[3].split("/");
      var d = new Date(coldate[2], coldate[1] - 1, coldate[1]);
      var date = moment(d.toISOString());
      date = date.format("YYYY-MM-DD");
      dateMin = startdate.replace(/-/g, "");
      dateMax = enddate.replace(/-/g, "");
      date = date.replace(/-/g, "");
      if (dateMin == "" && date <= dateMax) {
         return true;
      } else if (dateMin == "" && date <= dateMax) {
         return true;
      } else if (dateMin <= date && "" == dateMax) {
         return true;
      } else if (dateMin <= date && date <= dateMax) {
         return true;
      }
      return false;
   }
});
table_1.draw()
});

你能帮我找到解决办法吗... 我不确定我哪里出错了。

Via assistance received from Datatables.net forum.

var startdate;
var enddate;

 $.fn.dataTableExt.afnFiltering.push(
 function (oSettings, aData, iDataIndex) {
 if (typeof startdate === 'undefined' || typeof enddate === 'undefined') {
 return true;
  }
  var coldate = moment(aData[3], 'DD-MM-YYYY');
   console.log('coldate', coldate)

   var valid = true;

  if (coldate.isValid()) {
   if (enddate.isBefore(coldate)) {
    console.log('enddate before coldate', enddate)
    valid = false;
   }

  if (coldate.isBefore(startdate)) {
  console.log('coldate before startdate', startdate)
  valid = false;
 }
  } else {
  valid = false;
 }

 return valid;
