MVC在单击按钮时从JSon对象填充JQuery数据表时出现问题

我有一个MVC页面，其中有一个JQuery数据表，我希望在用户单击Query按钮时填充该表

这是我的数据表：

<table id="mytable" class="table table-striped table-bordered mt-5">
<thead>
    <tr>
        <th>Column 1</th>
        <th>Column 2</th>
        <th>Column 3</th>
        <th>Column 4</th>
        <th>Column 5</th>
        <th>Column 6</th>
        <th>Column 7</th>

    </tr>
</thead>
<tbody></tbody>
</table>

下面是当用户单击查询按钮时调用的函数：

$('#mytable').DataTable({
    processing: true, // for show progress bar
    order: [[2, "desc"]],
    dataSrc: 'vm',
    dom: 'rfltip',
    bRetrieve: true,
    iDisplayLength: 50,
    columns: [
        { "data": "COL1" },
        { "data": "COL2" },
        { "data": "COL3" },
        { "data": "COL4" },
        { "data": "COL5" },
        { "data": "COL6" },
        { "data": "COL7" }
    ]
});

function QueryEvents() {
      $.ajax({
            url: "/MyController/MyJsonRequest",
            type: "get",
            data: {
                id: $("#id").val()
            },
            error: function (response) {

                console.log("response: " + response);
            }

        })
        .done(function (result) {              

            var table = $('#mytable').DataTable();
            table.clear().draw();
            console.log('good to here' + JSON.stringify(result));
            table.rows.add(result).draw();

        });
};

对控制器的调用正在运行并返回一个Json对象。下面是console.log条目中的对象列表，因此我知道正在返回数据：

good to here{"vm":[{"COL1":"0000000017","COL2":"Balance - 4 Place","COL3":"2334234","COL4":"INS1234","COL5":"smith, joe","COL6":"Yearly Maint","COL7":"/Date(1582314988910)/"},{"COL1":"0000000018","COL2":"Balance - 4 Place","COL3":"2334234","COL4":"INS1234","COL5":"jones, billy","COL6":"Yearly Maint","COL7":"/Date(1582314988910)/"}]}

---

它是格式良好的json，我没有收到任何错误，但是数据表没有填充。不确定我遗漏了什么？

以下是您在控制台上打印的对象

{"vm":[{"COL1":"0000000017","COL2":"Balance - 4 Place","COL3":"2334234","COL4":"INS1234","COL5":"smith, joe","COL6":"Yearly Maint","COL7":"/Date(1582314988910)/"},{"COL1":"0000000018","COL2":"Balance - 4 Place","COL3":"2334234","COL4":"INS1234","COL5":"jones, billy","COL6":"Yearly Maint","COL7":"/Date(1582314988910)/"}]}

但DataTable只需要内部数组

[{"COL1":"0000000017","COL2":"Balance - 4 Place","COL3":"2334234","COL4":"INS1234","COL5":"smith, joe","COL6":"Yearly Maint","COL7":"/Date(1582314988910)/"},{"COL1":"0000000018","COL2":"Balance - 4 Place","COL3":"2334234","COL4":"INS1234","COL5":"jones, billy","COL6":"Yearly Maint","COL7":"/Date(1582314988910)/"}]

所以你应该使用

table.rows.add(result.vm).draw();

而不是

table.rows.add(result).draw();
