Moment.js日期转换不适用于DataTable

Question

我有一个DataTable，其中包含日期的格式如下： "/Date(1185336000000)/" 。

在下面的代码中，我按照DataTable的文档集成了Moment.js以进行日期转换-我遗漏了一些东西或者我的代码编写不正确。 或两者。

有什么想法吗？ 我相信部分问题在于function loadPH ，但我不想删除它。

JS代码段：

import $ from 'jquery';
import admissData from '../JSON/sk-admiss.json';
import DataTable from 'datatables.net';

import moment from 'moment';

function loadPH() {
    let admissText = admissData.d.results
    .filter(x => x.p_h_v !== "")
    .map(function(val) {
        return {
            "PH": val.p_v_h,
            "Stuff": val.stuff,
            ...
            ...
            "Date of Admission": val.dateofadmission,
            ... // ----- irrelevant info
        }
    })

    $.fn.DataTable.moment('MMM Do YY'); // ---- console error: "default.a.fn.DataTable.moment is not a function"
    $('#prohac-table').DataTable({
        columns: [
            { data: "PH" },
            { data: "Stuff" },
            ...
            ...
            { data: "Date of Admission" },
            ... // ----- irrelevant info
        ],
        columnDefs: [{
            type: 'date',
            targets: [4]
        }],
        data: admissText
    });

}

loadPH();

这是我将如何处理奇怪的日期格式"/Date(1185336000000)/" ，我假设它是Unix时间戳（以毫秒为单位）。

首先，从代码中删除该行： $.fn.DataTable.moment('MMM Do YY');

然后， processStrangeDate() （ 可以根据需要随意重命名 ）将成为获取Unix时间戳并使用Moment.js进行转换的函数。

function parseDate(strangeDate){
  return moment(parseInt(strangeDate.split("(")[1])).format('MMM Do YY');
}

这是一个简单的演示：

 var strangeDate = "/Date(1185336000000)/"; // A function to process that strange date format function processStrangeDate(strangeDate){ return moment(parseInt(strangeDate.split("(")[1])).format('MMM Do YY'); } // Processing example var strangeDate = "/Date(1185336000000)/"; console.log(processStrangeDate(strangeDate)); 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script> 

以及如何在DataTables中使用它：

 // A function to process that strange date format function processStrangeDate(strangeDate){ return moment(parseInt(strangeDate.split("(")[1])).format('MMM Do YY'); } // Example in dataTables using columnDef $("#example").dataTable({ data:[ ["Line 1","/Date(1185336000000)/","/Date(1185336000000)/"] ], columnDefs:[ { targets:2, render: function(data){ // Target is the column # zero-based return processStrangeDate(data); } } ] });

更新：我做了一些挖掘，解决方案涉及到使用columnDefs ：

        { data: "x" },
        { data: "y" },
        { data: "z" },
        { data: "zz" },
        { data: "Date of Admission" }, // ----- target
        ...
           { data: "Classification" }
        ],
        columnDefs: [
            {"type":"unix","targets":4,"render": function(data) { 
                return moment.utc(data, "x").format('MM/DD/YYYY')
            }}, // targets must be plural
        ],
