javascript - 数据未加载到数据表中

Question

我使用以下代码使用 ajax 加载数据表。数据未加载到数据库中，

$('#new_table').DataTable({
    "processing": true,
    "serverSide": true,
    "ajax":{
    "url": "<?php echo base_url();?>index.php/Members/membergetajax",
    "dataType": "json",
    "type": "POST",
    "dataSrc": "",
    },
    "lengthMenu": [5, 10, 20, 50, 100],
    "pageLength": 5,
    "columnDefs": [{
        "className": "dt-center", "targets": 0
    },{
        "className": "dt-center", "targets": 1
    },{
        "className": "dt-center", "targets": 2
    }],
    "columns": [
        { "data": "id"},
        { "data": "first_name" },
        { "data": "member_id" }
    ]   
});

ajax的数据格式

 "data":[
     {"id":"1","first_name":"Arun","member_id":"Mem01"},
     {"id":"2","first_name":"Dinesh","member_id":"  Mem02 "},
     {"id":"3","first_name":"Ramesh  ","member_id":"Mem03 "},
     {"id":"4","first_name":"Mahesh ","member_id":"Mem04 "},
     {"id":"5","first_name":"Rajesh ","member_id":"Mem05"}
 ]

请帮我找出问题，提前致谢

根据documentation你有两种可能性:

• 将dataSrc设置为data -->"dataSrc": "data"

• 您的 ajax 调用应该只返回数据值:

  [{
     "id": "1",
     "first_name": "Arun",
      "member_id": "Mem01"
  }, {
     "id": "2",
     "first_name": "Dinesh",
     "member_id": "  Mem02 "
  }, {
      "id": "3",
      "first_name": "Ramesh  ",
      "member_id": "Mem03 "
  }, {
      "id": "4",
      "first_name": "Mahesh ",
      "member_id": "Mem04 "
  }, {
      "id": "5",
      "first_name": "Rajesh ",
      "member_id": "Mem05"
  }]
