ionic4 路由跳转、ionic4 路由跳转传值 NavController 返回上一页 、NavController 回到根

1、普通路由跳转

 

<ion-button [routerLink]="['/pinfo']">
跳转到详情
</ion-button>

 

<ion-header> <ion-toolbar>
<ion-buttons slot="start">
<ion-back-button defaultHref="/tabs/tab1" text="返回"></ion-back-button>
</ion-buttons>
<ion-title>pinfo</ion-title> </ion-toolbar>
</ion-header>

2、路由跳转传值

 

<ion-button [routerLink]="['/pinfo']" [queryParams]="{aid:'1234'}">
跳转到详情并传值
</ion-button>

 

import { Component, OnInit } from '@angular/core'; import { ActivatedRoute } from '@angular/router';
@Component({
selector: 'app-pinfo', templateUrl: './pinfo.page.html', styleUrls: ['./pinfo.page.scss'],
})
export class PinfoPage implements OnInit {
constructor(public route:ActivatedRoute) { } ngOnInit() {
this.route.queryParams.subscribe((data)=>{ console.log(data);
}) }
}

3、NavController 返回上一页

 

Ionic4.x 中从 tabs 切换页面跳转到其他页面，使用 ion-back-button 返回的话，默认都会返回 到 tab1 页面。如果我们想从那个 tab 页面跳转过去就返回到指定的 tab 页面的话，这时候就 要用到 NavController 里面提到的 back 方法。

 

import { NavController } from '@ionic/angular'; constructor(public nav:NavController) { } 
this.nav.back(); 
this.nav.navigateBack('/tabs/tab3');

 

完整代码

<ion-header> <ion-toolbar>
<ion-buttons slot="start"> <ion-button (click)="goBack()">
<ion-icon slot="icon-only" name="arrow-back"></ion-icon> </ion-button>
</ion-buttons>
<ion-title>pinfo</ion-title> </ion-toolbar>
</ion-header>

import { Component, OnInit } from '@angular/core'; 
import { ActivatedRoute } from '@angular/router'; 
import { NavController } from '@ionic/angular';
@Component({
　　selector: 'app-pinfo', 
　　templateUrl: './pinfo.page.html', 
　　styleUrls: ['./pinfo.page.scss'],
})
export class PinfoPage implements OnInit {
constructor(
　　public route:ActivatedRoute,public nav:NavController) { } 
ngOnInit() {
this.route.queryParams.subscribe((data)=>{
　　 console.log(data);
})
　　console.log(window.history); }
goBack(){ 
　　this.nav.navigateBack('/tabs/tab3');
} 
}

4、NavController 回到根

import { NavController } from '@ionic/angular'; 
constructor(public nav:NavController) { } 
this.nav.navigateRoot('/tabs/tab3');
