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');
