在 nativescript 中看不到 console.log() 中的值

Can't see values in console.log() in nativescript

我有一个包含数组的 js 文件! js文件是这样的

export const appointments = [
{
  "taskID": 9018929,
  "resource_ID": 1,
  "title": "KNDL Thatcham",
  "description": "<Non-Selected>\r\n10:00 - 18:00",
  "startTime": "2018-12-28T00:00:00",
  "endTime": "2018-12-28T23:59:00",
  "statusColour": "#DFDFDF",
  "clientColour": "#FFFDD7"
}]

我已经在 service.ts 中导入了这个 js 文件。而这个 appointments.js 没有显示在 console.log.

import { Injectable } from '@angular/core';
        import { appointments } from '../appointments';
        import { Color } from "tns-core-modules/color";
        // >> angular-calendar-require
        import { CalendarEvent } from 'nativescript-ui-calendar';


        @Injectable({
        providedIn: 'root'
        })


    export class CalendarService {

      constructor() { 
      //var a="test test etsdhsakdsakd dsddssdsd";
      console.log(appointments);
    } 

这是我导入 service.ts

的组件
import { Component, OnInit } from '@angular/core';

import { CalendarService } from "./service/calendar.service";
import { RadCalendar, CalendarEvent, CalendarSelectionEventData } from "nativescript-ui-calendar";
@Component({
  selector: 'ns-calendar',
  templateUrl: './calendar.component.html',
  styleUrls: ['./calendar.component.css'],
  moduleId: module.id,
  providers: [CalendarService]
})
export class CalendarComponent implements OnInit {
}

您需要在构造函数中添加一个类型为 CalendarService 的私有 calendarService 参数。

当Angular 创建 CalendarComponent 时,Dependency Injection 系统将 calendarService 参数设置为 CalendarService 的单例实例。

export class CalendarComponent 实现 OnInit { 构造函数(日历服务:日历服务){}

}
