问题描述
我查看了如何在Angular 2中返回星期数.我没有找到这个问题的答案.我确实在 https://docs.angularjs.org/api/ng/filter/date找到了在Angular 1中将是这样的:{{today | date:'w'}}，但在Angular 2中似乎不起作用.我知道我可以编写一个函数来处理此问题，但这似乎不切实际.我是否在有关Angular 2的文档中丢失了某些内容?还是尚未实现?
I looked up how to return the week number in Angular 2. I have not found an answer to this question.I did find on https://docs.angularjs.org/api/ng/filter/date that in Angular 1 it would be something like this: {{today | date:'w'}} but this does not seem to work in Angular 2. I know I can write a function to take care of this but this doesn't seem practical. Am I missing something in the documentation about Angular 2 or is this not (yet) implemented there?
推荐答案
DatePipe 当前不支持weekOfYear.
不过，您可以实现自己的WeekOfYear管道.
请参阅 https://angular.io/docs/ts/latest/guide/pipes. html 以获得更多详细信息.
You can implement your own WeekOfYear pipe though.
See https://angular.io/docs/ts/latest/guide/pipes.html for more details.
