Ionic2/Cordova typescript 项目中的 Moment.js 插件 [英] Moment.js plugins in Ionic2/Cordova typescript project

问题描述

在我用 Typescript 编写的 Ionic 2 项目中，我使用了 moment.js 库.我使用代码片段导入它:

In my Ionic 2 project written in Typescript I use moment.js library. I import it using code snippet:

import * as moment from 'moment';

这样做后，在我的组件中我可以正常使用moment，即:

After I do so, in my component I can use moment normally, ie:

let endDate = moment(data.endDate);

但是，现在我想使用一个专用于 moment.js 的插件——来自这个 repo 的 moment-weekday-calc:https://github.com/andruhon/moment-weekday-calc

however, now I want to use one of plugins dedicated to moment.js - moment-weekday-calc from this repo: https://github.com/andruhon/moment-weekday-calc

我已经通过 npm 安装了插件，但我无法让它运行.我试过了:

I've installed plugin via npm, but I am not able to make it running. I've tried:

import * as moment from 'moment';
import 'moment-weekday-calc';

//(...) - 我的组件代码在这里

//(...) - my component's code here

  let test = moment().isoWeekdayCalc({
    rangeStart: '1 Apr 2015',
    rangeEnd: '31 Mar 2016',
    weekdays: [1,2,3,4,5],
    exclusions: ['6 Apr 2015','7 Apr 2015'],
    inclusions: ['10 Apr 2015']
  }); //260

以上代码抛出错误:

Typescript Error
Property 'isoWeekdayCalc' does not exist on type 'Moment'.

知道如何在我的 ionic/cordova 的 typescript 应用程序中使用这个插件吗?

any idea how can I use this plugin in my typescript app for ionic/cordova?

推荐答案

由于该错误只是 typescript 抱怨 isoWeekdayCalc 未在 moment 的类型定义中定义，您可以像这样将其转换为 any:

Since that error is just typescript complaining about isoWeekdayCalc not being defined in the type definition of moment, you can just cast it to any like this:

let test = (<any>moment()).isoWeekdayCalc({
            rangeStart: '1 Apr 2015',
            rangeEnd: '31 Mar 2016',
            weekdays: [1,2,3,4,5],
            exclusions: ['6 Apr 2015','7 Apr 2015'],
            inclusions: ['10 Apr 2015']
        }); //260
