PS: I use angular2thank you in advance

Answer 1

利用Shared Services在组件之间传递数据，甚至可以出于这些目的利用event emitters

Answer 2

import {Injectable, Injector} from '@angular/core';

@Injectable()
export class DataService {
    data;
    constructor() {}
}

in your component

constructor(private dataService: DataService ){}
this.dataService.data= somedata;

in the other component

constructor(private dataService: DataService ){}
somedata= this.dataService.data;

remember to register your ap in the providers of the module being used;

providers: [DataService]

this can be used because the service injected in both components will be a singleton
