javascript - Java 8 LocalDate 到 JavaScript 日期

Question

我想将此 Java LocalDate 转换为 JavaScript Date:

{
    "date": {
        "year": 2016,
        "month": "NOVEMBER",
        "dayOfMonth": 15,
        "monthValue": 11,
        "dayOfWeek": "TUESDAY",
        "era": "CE",
        "dayOfYear": 320,
        "leapYear": true,
        "chronology": {
            "id": "ISO",
            "calendarType": "iso8601"
        }
    }

Answer 1

您的日期字符串未指定时区。您还缺少时间信息，而 JavaScript 日期通过设计存储一天中的时间。

您的字符串几乎是有效的 JSON，因此您可以通过 JSON.parse() 解析它。它只缺少一个结束 } 括号。

考虑到上面的评论，您可以使用以下方法:

var input = JSON.parse('{"date":{"year":2016,"month":"NOVEMBER","dayOfMonth":15,"monthValue":11,"dayOfWeek":"TUESDAY","era":"CE","dayOfYear":320,"leapYear":true,"chronology":{"id":"ISO","calendarType":"iso8601"}}}');
            
var day = input.date.dayOfMonth;
var month = input.date.monthValue - 1; // Month is 0-indexed
var year = input.date.year;

var date = new Date(Date.UTC(year, month, day));

console.log(date); // "2016-11-15T00:00:00.000Z"
