Angular跳转传值（get，动态路由，js）

Posted 2020-12-14 风子磊

一，get传值

 传

<ul *ngFor="let l of list;let ss=index;">
    <li><a routerLink="/newsDetail" [queryParams]="{aid:l.id}">{{l.content}}</a></li>

</ul>

接收

import { ActivatedRoute } from ‘@angular/router‘;

constructor(public router:ActivatedRoute) { }

//get获取传值
 this.router.queryParams.subscribe((data)=>{
   console.log(data)
 })

 二，动态路由传值

配置

{
    path:‘newsDetail/:id‘,component:NewDetailComponent
  }

跳转

<ul *ngFor="let l of list;let ss=index;">

  <li><a [routerLink]="[‘/newsDetail‘,l.id]">{{l.content}}</a></li>
</ul>

接收

import { ActivatedRoute } from ‘@angular/router‘;

constructor(public router:ActivatedRoute) { }

//动态路由
    this.router.params.subscribe((data)=>{
      console.log(data)
      this.id=data.id;
    })

 三、动态路由的js跳转

1, 引入

import { Router } from ‘@angular/router‘;

2.初始化

export class HomeComponent implements OnInit {
     constructor(private router: Router) {}
}

跳转

<button (click)="goHome()">goHome</button>

import { Router } from ‘@angular/router‘;

    //js跳转
  goHome(){
    //传值
    //this.router.navigate([‘/home‘,‘1‘])

    //不传值
    this.router.navigate([‘/home‘])
  }

 

四，js get传值

<button (click)="goGetHeader()">goGetHeader</button>

import { Router,NavigationExtras } from ‘@angular/router‘;

constructor(public router:Router) { }

  goGetHeader(){
    let queryParams:NavigationExtras={
      queryParams:{‘id‘:12}
    }

    this.router.navigate([‘/header‘],queryParams)

  }
