使用moment.js排序：弃用警告：提供的值不是可识别的RFC2822或ISO格式 [英] Sort with moment.js: Deprecation warning: value provided is not in a recognized RFC2822 or ISO format

问题描述

我解析了从带有Moment的API获得的日期，我需要在收集数据时对数组进行排序。我目前有这个：

  myobject.name = name; 
 myobject.time = Moment（ajaxinfo.startdate）.format（'DD / MM / YYYY'）; 
 array.push（myobject）; 
 // ...添加更多数据... 
 array.sort（（左，右）=> {
返回Moment.utc（left.time）.diff（时刻） .utc（right.time））; 
}）; 
  

ajaxinfo.startdate 是一个字符串，我从API获取，它看起来像2018-01-28T13：00：00 + 00:00

<但是上面的代码不起作用。它给了我一个警告：

弃用警告：提供的值不是公认的RFC2822或ISO格式。 时刻构造回落到js Date（），这在所有浏览器和版本中都不可靠。不鼓励使用非RFC2822 / ISO日期格式，并将在即将发布的主要版本中删除。请参阅 http://momentjs.com/guides/#/warnings/js-日期/ 了解更多信息。

如何才能使其有效？

解决方案

根据警告中指向momentjs文档的链接，浏览器在解析格式时可能不可靠或不一致提供DD / MM / YYYY。如果需要保留这种格式，一种解决方案是在计算 diff 时将字符串转换回moment对象时提供格式。所以你可以做
返回moment.utc（left.timeStamp，'DD / MM / YYYY'）。diff（moment.utc（right.timeStamp，'DD / MM / YYYY'） ）

I parse dates I get from an API with Moment, and I need to sort the array when I'm done collecting the data. I currently have this:

myobject.name = name;
myobject.time = Moment(ajaxinfo.startdate).format('DD/MM/YYYY');
array.push(myobject);
// ... more data is added ...
array.sort((left, right) => {
    return Moment.utc(left.time).diff(Moment.utc(right.time));
});

ajaxinfo.startdate is a string that I get from an API, and it looks like "2018-01-28T13:00:00+00:00"

But the above code doesn't work. It gives me a warning:

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.

How can I make it work?

解决方案

Based on the link to the momentjs docs in the warning, browsers may be unreliable or inconsistent in parsing the format you're providing "DD/MM/YYYY". If you need to keep this format, one solution would be to provide the format when converting the string back to a moment object when calculating the diff. So you could do return moment.utc(left.timeStamp, 'DD/MM/YYYY').diff(moment.utc(right.timeStamp, 'DD/MM/YYYY'))
