angular 常用模块import引入

import {Component, EventEmitter(发射事件,接收事件), Input, OnChanges, OnInit, Output, SimpleChanges} from "@angular/core";
import {NavigationCancel, NavigationEnd, Router,ActivatedRoute} from "@angular/router";
import {FormsModule,ReactiveFormsModule} from '@angular/forms';
import 'rxjs/Rx';  //响应式编程
import {Observable} from "rxjs";

import {FormControl} from "@angular/forms";

千万不要以为我多此一举,webstorm不支持这些快捷引入
