我有这么多导入的原因是因为我正在使用一个非常复杂的数据表。

JavaScript

<script type="text/javascript">
   var contractUrl = "Service.asmx/GetContracts";
   $(document).ready(function() {
    var table = $('#contracts').DataTable({
    dom: 'lBfrtip',
    stateSave: true,
    lengthChange: false,
        buttons: [
            'pageLength','excel'
        ],
    scrollY:        300,
    scrollX:        true,
    scrollCollapse: true,
    columnDefs: [
        { width: 200, targets: 0 }
    ],
    fixedColumns: true,
        stateSave: true,
    "processing": false,
    "serverSide": true,
    "ajax": {
        type: "POST",
        url: contractUrl,
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        },
    "columns": [ 
            { "data": "Code" }, 
            { "data": "ContractType" }],
    "lengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
    "pagingType": "full_numbers",
    "searching": false
} );

table.buttons().container()
    .appendTo( $('div.eight.column:eq(0)', table.table().container()) );
});

</script>

这是我的Json

[{"Code":"Dev","ContractType":"GPO"}]

您遇到的唯一语法错误是stateSave在配置对象上定义了两次属性。

我尝试使用您的代码 + 从他们的示例中获得的一些虚拟数据进行初始化。

我不得不注释掉ajax和columns属性。另外，我不得不评论stateSave（两次:)），但这可能与 StackOverflow 的限制有关。需要明确的是：在 SO 上可能无法拥有一次。拥有两次是一个错误，并且不会在任何地方工作。

其他一切似乎都很好，包括table.buttons().

由于配置对象上的重复属性DataTable()未正确启动，并且您尝试访问的方法未公开。

在这个例子中看到它的工作：

$(document).ready(function() {
  table = $('#contracts').DataTable({
    dom: 'lBfrtip',
    // stateSave: true,
    lengthChange: false,
    buttons: [
      'pageLength', 'excel'
    ],
    scrollY: 300,
    scrollX: true,
    scrollCollapse: true,
    columnDefs: [{
      width: 200,
      targets: 0
    }],
    fixedColumns: true,
    // stateSave: true,
    processing: false,
    // serverSide: true,
    /* "ajax": {
        type: "POST",
        url: contractUrl,
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        },
    // replaced with data, below
        */
    data: dataSet(),
    columns: [
      { title: "Name"},
      { title: "Position"},
      { title: "Office"},
      { title: "Extn."},
      { title: "Start date"},
      { title: "Salary"}
    ],
    lengthMenu: [
      [10, 25, 50, -1],
      [10, 25, 50, "All"]
    ],
    pagingType: "full_numbers",
    searching: false
  });
  table.buttons().container().appendTo($('div.eight.column:eq(0)', table.table().container()));
});

function dataSet(){return [
