格式化日期到新的日期不在IE中工作。

I currently have the following code:

我目前有以下代码:

lastLoginDate = "\/Date(1499994230140+0800)\/";
lastLoginDate = moment(lastLoginDate).format("YYYY-MM-DD hh:mm:ss UTC");
lastLoginDate = new Date(lastLoginDate);

This works in chrome. However when ran in IE, new Date returns invalid date. how do i achieve the same output in IE?

这在chrome工作。但是当在IE中运行时，新的日期会返回无效的日期。在IE中如何实现相同的输出?

3 个解决方案

#1

resolved my issue by changing format to yyyy/mm/dd instead of yyyy-mm-dd

解决了我的问题，改为yyyyy /mm/dd而不是yyyy-mm-dd。

moment(lastLoginDate).format("YYYY/MM/DD hh:mm:ss UTC");

#2

There is no need at all to format and then parse the date again. Just use toDate():

根本不需要格式化，然后再次解析日期。只使用迄今为止():

lastLoginDate = moment(lastLoginDate).toDate();

If this does not work, then your lastLoginDate has a wrong format. You can read more about valid formats here.

如果这不起作用，那么您的lastLoginDate格式错误。您可以在这里阅读更多有效的格式。

#3

You can split the string into the Unix time and the timezone offset by using a regex.

您可以使用正则表达式将字符串分割为Unix时间和时区。

This code below is easy to follow.

下面的代码很容易理解。

const dateRegex = /^\/Date\((\d+)([-+]\d{4})\)\/$/;
const dateFormat = 'YYYY-MM-DD hh:mm:ss Z';
  
let lastLoginDate = "\/Date(1499994230140+0800)\/";
console.log(parseTimestamp(lastLoginDate));

function parseTimestamp(timestamp) { 
  var groups = dateRegex.exec(timestamp);
  var unixTime = Math.floor(parseInt(groups[1], 10) / 1000);
  var timezoneOffset = groups[2];

  return moment.unix(unixTime).utcOffset(timezoneOffset).format(dateFormat);
}

// Output: 2017-07-14 09:03:50 +08:00
