使用ajax调用填充数据表

Question

我正在尝试使用 ajax 调用填充数据表。 但它只用columns最后一个值填充第一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。 我该如何解决这个问题？

数据输出

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

Answer 1

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

每列都应该是一个单独的对象，其数据属性指向记录上的属性名称。

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

Answer 2

您的列 def 是一个对象，而不是一个对象数组。

每个列配置都需要一个data字段和一个可选的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 }

更改您的代码如下

 $(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",},
            }]
        })
    })

您可以通过添加过滤或启用搜索来自定义每一列：

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