Question

我在数据表中获取数据，但我想要数据加载数据。

$('#userdata').DataTable({
        "ajax" : "/searchuser1?emp="+emp,
        "bDestroy":true,
        "columns":[
                    {"data": "empid1"},                                                             
                    {"data": "name"},
                    {"data": "phone"},
                    {"data": "logintime"},
                    {"data": "logouttime"}
                   ],

                   "order": [[ 1, "desc" ]],
                   "language": {
                       "lengthMenu": "| View _MENU_ records per page",
                       "zeroRecords": "Nothing found - sorry",
                       "infoEmpty": "No records available",
                       "infoFiltered": "(filtered from _MAX_ total records)"
                   },
                   "pagingType": "full_numbers",
                  "lengthChange": false 
        });

我尝试了以下方式，但我不知道它在数据表中写入了什么

var totalRecords =$("#userdata").DataTable().page.info().recordsTotal;
 alert(totalRecords);

试试这个，

    $('#userdata').DataTable({
            "ajax" : "/searchuser1?emp="+emp,
            "bDestroy":true,
            "columns":[
                        {"data": "empid1"},                                                             
                        {"data": "name"},
                        {"data": "phone"},
                        {"data": "logintime"},
                        {"data": "logouttime"}
                       ],

                       "order": [[ 1, "desc" ]],
                       "language": {
                           "lengthMenu": "| View _MENU_ records per page",
                           "zeroRecords": "Nothing found - sorry",
                           "infoEmpty": "No records available",
                           "infoFiltered": "(filtered from _MAX_ total records)"
                       },
                       "pagingType": "full_numbers",
                      "lengthChange": false 
            });  

            //By methods 
            function getCount(){
              var totalRecords  =$("#userdata").DataTable().page.info().recordsTotal;
             alert(totalRecords);
           }

Datatable有inbuild函数来获取这样的长度

change this
'post_type' => 'array ('episodes')',
to
'post_type' => 'episodes',
or
'post_type' => 'array ("episodes")',

如何在jquery中获取Datatable上的记录长度
