如何将momentjs datetime转换为字符串，反之亦然
如何将momentjs datetime转换为字符串，反之亦然
提问于 2019-03-02 00:42:49
我使用以下命令计算datetime
datetime_from_moment = moment.utc().utcOffset('+0530')然后将其转换为字符串，这样我就可以将其保存到firebase实时数据库中，如下所示：
datetime_from_moment_string = datetime_from_moment.toString()过了一段时间后，我从数据库中获得了datetime (它是字符串格式)来做一些计算。要进行这些计算，我必须将该字符串转换为矩类型。我该怎么做呢？
字符串类型moment datetime看起来像这样的Fri Mar 01 2019 22:07:56 GMT+0530
要转换它，我执行以下datetime_converted = moment(datetime_from_moment_string)
但是我得到了这个错误：
Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

您需要小心地构建您的格式字符串。如果将DateTime字符串格式化得更好，这将会容易得多。但根据您提供的内容，我认为这应该是可行的。
moment("Fri Mar 01 2019 22:07:56 GMT+0530").format('dddd MMMM Do YYYY HH:mm:ss Z');http://jsfiddle.net/qp8xfgkc/
