Jump angular routing and parameter passing

? 1. a routing jump method: / routing id = '001' mode - queryParams manner

　Routing Configuration: {path: 'Details' , Component: bookDetailsComponent }

   . A jump instruction:

　　<a [routerLink]="['/details']" [queryParams]="{id: item.id}" style="color:blue; font-size: 12px;cursor:pointer">查看详情</a>

　　routerLink: Jump route, in the form of an array, there are two transmission parameters written: 1. [queryParams] = "{ID: item.id}", 2. [routerLink] = "[ '/ Details', ID]" the first routing value in the array, the value of the second parameter to be passed

  . B js achieve Jump:

　　

Where Router is an example of this.router

import  { Router } from '@angular/router'

constructor(private router: Router) {

 }

 jumpDetial ( bookId : string ) : void {

        this.router.navigate(['/details'], {

            queryParams: {

                ID: bookId

            }

        })

    }

this.router.navigate ([ 'user', 1]); root routing jump starting

this.router.navigate ([ 'User',. 1], { the relativeTo : route}); default is the root route, after setting relative to the current routing jump, jump to the sub-route

this.router.navigate ([ 'user', 1], {queryParams: {id: 1}}); parameter transfer route / user / 1 id = 1?

this.router.navigate(['view', 1], { preserveQueryParams: true }); 默认值为false，设为true，保留之前路由中的查询参数/user?id=1 to /view?id=1

this.router.navigate(['user', 1],{ fragment: 'top' }); 路由中锚点跳转 /user/1#top

this.router.navigate(['/view'], { preserveFragment: true }); 默认值为false，设为true，保留之前路由中的锚点/user/1#top to /view#top

this.router.navigate(['/user',1], { skipLocationChange: true }); 默认值为false，设为true路由跳转时浏览器中的url会保持不变，但是传入的参数依然有效

this.router.navigate(['/user',1], { replaceUrl: true }); 未设置时默认为true，设置为false路由不会进行跳转

2. 以 /路由/参数  的方式跳转 -- snapshot方式

 路由配置：  { path: 'details/:id', component: bookDetailsComponent }

1. 指令跳转传参：

　　

　　<a [routerLink]="['/details', item.id]"</a>

2. js 跳转：

　　

　　this.router.navigate(['/details', '1']

 

3. 获取参数

a. 快照方式获取参数 snapshot

this.queryParams = this.route.snapshot.params['id']

b. queryParams 方式获取参数

this.route.queryParams.subscribe(params=>{

　　this.queryParams = params['id']

    console.log(this.queryParams)

})
