本文实例讲述了Angular 2使用路由自定义弹出组件toast操作。分享给大家供大家参考，具体如下：

原理：

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 name='apps'></router-outlet>
<router-outlet name='popup'></router-outlet>

浏览器的导航栏中则这样显示

http://127.0.0.1:4200/(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 class="box">
 <div class="toast-box">
 <p class="toast-title">提示</p>
 <div class="toast-content">
 <ng-container *ngIf="toastParams.img">
 <img src="{{toastParams.img}}" class="toast-content-img">
 </ng-container>
 <ng-container *ngIf="toastParams.title">
 <p class="toast-content-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
 });
}
