javascript - 扁平化 JSON 数据

Question

我正在尝试使用 Tabulator 创建工单列表，数据通过 AJAX url 从工单系统导入为 JSON，如下所示。

{
    "results": [
        {
            "cc_emails": [
                "ram@freshdesk.com",
                "diana@freshdesk.com"
            ],
            "fwd_emails": [],
            "reply_cc_emails": [
                "ram@freshdesk.com",
                "diana@freshdesk.com"
            ],
            "ticket_cc_emails": [
                "ram@freshdesk.com",
                "diana@freshdesk.com"
            ],

                "cf_category": null,
                "cf_firstname": null,
                "cf_surname": null,
                "cf_user_trainging": null,
                "cf_email_address": null,

                "cf_location": "A1"
            },
            "created_at": "2019-06-24T15:11:47Z",
            "updated_at": "2019-06-24T15:59:00Z",
            "associated_tickets_count": null,
            "tags": []
        }
    ],
    "total": 1
}

问题是“custom_fields”是主 JSON 对象内的一个 JSON 对象，有没有办法将这些数据展平并在 Tabulator 中显示为所有一行？有什么帮助吗？

我在 Tabulator 中的当前结果是它为 custom_fields 列返回 [object Object]。我希望能够看到行中的每个 custom_fields。

处理嵌套数据

不需要扁平化对象，Tabulator可以处理列的嵌套数据，如果你在字段名中使用点符号:

var table = new Tabulator("#example-table", {
    columns:[
        {title:"Category", field:"custom_fields.cf_category"},  //link column to nested field
    ],
});

有关嵌套数据处理的完整详细信息可以在 Columns Documentation 中找到

列分组

如果您愿意，您还可以使用列分组来显示字段是另一个属性的子集，例如，我们可以像往常一样定义顶级列，然后添加列组来保存自定义列

var table = new Tabulator("#example-table", {
    columns:[
        {title:"Subject", field:"subject"},  //standard column
        {title:"Priorty", field:"priority"}, //standard column
        {title:"Custom", columns:[ //column group to hold columns in custom_fields property
            {title:"Category", field:"custom_fields.cf_category"}, 
            {title:"First Name", field:"custom_fields.cf_firstname"}, 
        ]},
    ],
});
