如何将无效的日期字符串转换为Javascript日期(How to convert an invalid date string to Javascript date)

如何将无效的日期字符串转换为Javascript日期(How to convert an invalid date string to Javascript date)

我从REST API中获取无效的日期字符串，但我可能无法修复REST API。 如何格式化无效的日期字符串，如“20180517T010237”？

我试着用那个时刻，但我不能成功。

let date = moment("20180517T010237", "YYYY-MM-DD T HH.mm.ss").toDate();

有没有简单的方法呢？

I fetch invalid date strings from the REST API but i may not fix the REST API. How can i format an invalid date strings like that "20180517T010237" ?

I tried to use moment for that, but i couldnt succeed.

let date = moment("20180517T010237", "YYYY-MM-DD T HH.mm.ss").toDate();

is there any easy way to do that?

您传递的第二个字符串是您要解析的字符串的格式。 您的格式字符串包含-和输入中没有的空格。 删除它们：

let date = moment("20180517T010237", "YYYYMMDDTHHmmss").toDate();

请注意，它将在当地时间解析。 如果您想要UTC，请使用moment.utc ：

let date = moment.utc("20180517T010237", "YYYYMMDDTHHmmss").toDate();

例：

let date = moment("20180517T010237", "YYYYMMDDTHHmmss").toDate();
console.log(date);

date = moment.utc("20180517T010237", "YYYYMMDDTHHmmss").toDate();
console.log(date);

The second string you pass moment is the format of the string you're parsing. Your format string has - and spaces that aren't in your input. Remove them:
 
let date = moment("20180517T010237", "YYYYMMDDTHHmmss").toDate();
 
Note that it will be parsed in local time. If you want UTC instead, use moment.utc:
 
let date = moment.utc("20180517T010237", "YYYYMMDDTHHmmss").toDate();
 
Example:
 
 
 
  
  
let date = moment("20180517T010237", "YYYYMMDDTHHmmss").toDate();
console.log(date);

date = moment.utc("20180517T010237", "YYYYMMDDTHHmmss").toDate();
console.log(date);
