Angular 2使用路由自定义弹出组件toast操作示例

使用Angular2的命名路由插座，一个用来显示app正常的使用，一个用来显示弹出框，

<router-outlet></router-outlet> <router-outlet></router-outlet>

浏览器的导航栏中则这样显示

:4200/(popup:toast//apps:login)

路由配置

const rootRoute: Routes = [ { path: 'lists', component: Lists, outlet: 'apps', children: [ ... ] }, { path: 'toast', component: Toast, outlet: 'popup', }, ... ];

toast内容

<div> <div> <p>提示</p> <div> <ng-container *ngIf="toastParams.img"> <img src="https://www.jb51.net/{{toastParams.img}}"> </ng-container> <ng-container *ngIf="toastParams.title"> <p>{{toastParams.title}}</p> </ng-container> </div> </div> </div>

ts

在ngOninit函数中获取显示的参数即可

this.toastParams = this.popupSVC.getToastParams();

创建用来跳转至popup路由的服务，例如popup.service

import { Injectable } from '@angular/core'; import { Router } from '@angular/router'; @Injectable() export class PopupService { private toastParams; private loadingParams; constructor( private router: Router ) { } toast(_params) { this.toastParams = _params; let _duration; if (_params.duration) { _duration = _params.duration; } else { _duration = 500; } const _outlets = { 'popup': 'toast' }; this.router.navigate([{ outlets: _outlets }]); setTimeout(() => { const _outlets2 = { 'popup': null }; this.router.navigate([{ outlets: _outlets2 }]); }, _duration); } getToastParams() { return this.toastParams; } }

使用：

一、在app.module.ts中将服务导进来，注册

import { PopupService } from './svc/popup.service'; @NgModule({ imports: [ ... ], declarations: [ ... ], providers: [ PopupService, ... ], bootstrap: [AppComponent] })

二、在使用的test.ts中导入

import { PangooService } from './svc/pangoo.service'; constructor( private popupSVC: PopupService, ) { }

三、在html中定义一个函数

<div (click)="test()"></div>

四、调用

test(){ this.popupSVC.toast({ img: '弹出图片地址！', title: '弹出消息内容！', duration: 2000, //toast多久后消失，默认为500ms }); }
