使用ajax调用填充数据表

datatable ajax jquery javascript

KbiR · 技术社区 · 4 年前

我试图使用ajax调用填充数据表。但它只在第一列中填入 columns

这是我的代码:

$(document).ready(function() {
  $.ajax({
    url: "http://192.168.2.32:5000/get_all_locations",
    'method': 'GET',
    'contentType': 'application/json'
  }).done(function(data) {
    console.log('dataaa', data);
    $('#myTable').dataTable({
      'aaData': data['data'],
      "columns": [{
        "data": "id",
        "data": "name",
        "data": "code"
      }]
    })
  })
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<table id="myTable" class="table table-bordered table-striped">
  <thead>
    <tr>
      <th>id</th>
      <th>name</th>
      <th>Code</th>
    </tr>
  </thead>
</table>

在上图中,id字段显示代码的值。我该怎么解决?

    {â¦}
    â
    StatusCode: true
    â
    StatusDescription: "Location details has been pulled successfully."
    â
    data: (9) [â¦]
    ââ
    0: Object { code: "1007", id: 20, is_free_zone: true, â¦ }
    ââ
    1: Object { code: "1002", id: 15, is_free_zone: false, â¦ }
    ââ
    2: Object { code: "1001", id: 14, is_free_zone: false, â¦ }
    ââ
    3: Object { code: "1003", id: 16, is_free_zone: false, â¦ }
    ââ
    4: Object { code: "1004", id: 17, is_free_zone: false, â¦ }
    ââ
    5: Object { code: "1006", id: 19, is_free_zone: false, â¦ }
    ââ
    6: Object { code: "1005", id: 18, is_free_zone: false, â¦ }
    ââ
    7: Object { code: "1008", id: 21, is_free_zone: false, â¦ }
    ââ
    8: Object { code: "1009", id: 22, is_free_zone: false, â¦ }
    ââ
    length: 9

见 https://datatables.net/examples/ajax/objects.html

每一列都应该是一个单独的对象,数据属性指向记录上属性的名称。

columns: [
    {"data": "id"},
    {"data": "name"},
    {"data": "code"}
]

更改代码如下

 $(document).ready(function () {
    $.ajax({
        url: "http://192.168.2.32:5000/get_all_locations",
        'method': 'GET',
        'contentType': 'application/json'
    }).done(function (data) {
        console.log('dataaa', data);
        $('#myTable').dataTable({
            'aaData': data['data'],
            "columns": [
                { "data": "id", },
                { "data": "name", },
                {"data": "code",},
            }]
        })
    })

{"data": "code","orderable": false, "searchable": false,},

列定义是一个对象,而不是一个对象数组。

每列配置需要 data 字段和可选 title

let data = requestData();

$(() => {
  $("#myTable").DataTable({
    aaData: data['data'],
    columns: [
      { "data" : "id"   , "title": "ID"   },
      { "data" : "name" , "title": "Name" },
      { "data" : "code" , "title": "Code" }
    ]
  })
});

function requestData() {
  return {
    data : [
      { code: "1007", id: 20, name: "a", is_free_zone: true  },
      { code: "1002", id: 15, name: "b", is_free_zone: false },
      { code: "1001", id: 14, name: "c", is_free_zone: false },
      { code: "1003", id: 16, name: "d", is_free_zone: false },
      { code: "1004", id: 17, name: "e", is_free_zone: false },
      { code: "1006", id: 19, name: "f", is_free_zone: false },
      { code: "1005", id: 18, name: "g", is_free_zone: false },
      { code: "1008", id: 21, name: "h", is_free_zone: false },
      { code: "1009", id: 22, name: "i", is_free_zone: false }
    ]
  };
}

#myTable th, #myTable td { padding: 0.33em }
#myTable th { font-size: 0.90em }
#myTable td { font-size: 0.75em }
