【问题标题】：jQuery DataTable fails when adding rows with unknown request parameter添加具有未知请求参数的行时，jQuery DataTable 失败
【发布时间】：2018-12-13 01:34:52
【问题描述】：

我有一个数据表，我想通过调用服务并在其中添加新行来重绘它。

为此，我使用以下代码：

$(function() {
    var dataFromService = [{
        "ScheduleId": 1324,
        "Started": "26 Oct 2018 06:12:17",
        "EstimatedCompletionTime": "26 Oct 2018 10:12:49",
        "EstTimeToComplete": 240,
        "NoDelScheduled": 3,
        "NoPartsScheduled": 11,
        "NoSheetsScheduled": 534,
        "NoPartsPrepared": 5,
        "NoSheetsPicked": 312,
        "NoBlocksUsed": 64,
        "NoPalletsUsed": 3,
        "SheetsPerMin": 1.3,
        "SecondsPerSheet": 46.15
    }];

    $('#btnRedraw').on('click', function() {


        var datatable = $('#testDataTable001').DataTable();
        datatable.clear();
        datatable.rows.add(dataFromService);
        datatable.draw();
        //console.log(datatable);
    });
})

【问题讨论】：

按钮上不需要datatable.clear();。使用数据表的全局实例。请检查我的答案。

保持DataTable 实例在需要时全局重用该对象。点击按钮时不需要datatable.clear();。

【讨论】：

为什么你添加了 html 代码但是你没有改变它的任何内容？
好吧，你说实话。但我的第一个解决方案正在奏效。你可以检查一下。
@MargulanZharkenov 我更新了答案。这是解决此问题的唯一方法，因此可能存在相似之处。

【解决方案2】：

您可以使用此代码：

var dataFromService = [
    1324,
    "26 Oct 2018 06:12:17",
    "26 Oct 2018 10:12:49",
    240,
    3,
    11,
    534,
    5,
    312,
    64,
    3,
    1.3,
    46.15
];

$('#btnRedraw').on('click', function() {
    var datatable = $('#testDataTable001').DataTable();
    datatable.clear();
    datatable.row.add(dataFromService); // Here not rows, just row
    datatable.draw();
    console.log(datatable);
});

然后你的警告就会消失。

多行：

var dataFromService = [
    [
      1324,
      "26 Oct 2018 06:12:17",
      "26 Oct 2018 10:12:49",
      240,
      3,
      11,
      534,
      5,
      312,
      64,
      3,
      1.3,
      46.15
  ]
];
var datatable = $('#testDataTable001').DataTable();
$('#btnRedraw').on('click', function() {
  for (var i = 0; i < dataFromService.length; i++) {
      datatable.row.add(dataFromService[i]);
  }
  datatable.draw();
  console.log(datatable);
});
