javascript - 无法将字符串格式化为日期

Question

当我尝试将字符串值转换为日期时，收到错误消息“无效日期”

timestamp : string = "2017:03:22 08:45:22";
.
.
let time = new Date(timestamp);
console.log("Time: ",time); //here I get   Time: Invalid date

Answer 1

由于您的字符串必须采用 ISO 日期格式，因此您可以像下面的代码一样更改它:

let timestamp : string = "2017:03:22 08:45:22";

let timestampISO : string = timestamp.replace(':','-').replace(':','-').replace(' ','T');

let time = new Date(timestampISO);

console.log("Time: ",time);
