1. 问号后面带的参数
url:http://localhost:4200/news?key=japan
html 调用方法:
<a [routerLink]="[‘/news‘]" [queryParams]="{key:‘japan‘}"> 跳转
ts 调用方法:
private router: Router
this.router.navigate([‘/news‘], {queryParams: {key : ‘japan‘}});
获取参数方法:
private route: ActivatedRoute;
this.route.queryParams.subscribe(queryParams=> {
console.log(queryParams.key);
});
const key = this.route.snapshot.queryParams[‘key‘];
console.log("key", key);
2. 路由路径传参
url:http://localhost:4200/news/japan (注意:这里的路由参数是必须的)
路由路径配置:
path: ‘news/:key‘,
component: NewsComponent
html 调用方法:
<a [routerLink]="[‘/news‘,‘japan‘]"> 跳转
ts 调用方法:
private router: Router
this.router.navigate([‘/news‘, ‘japan‘]);
获取参数方法:
this.route.params.subscribe(params => {
console.log("params", params.key);
});
const key = this.route.snapshot.params[‘key‘];
console.log("key", key);
3. 在路由配置中传参(注意:可以用于自定义路由预加载)
路由路径配置:
path: "news",
component: NewsComponent,
data: {key: "hero"}
获取参数方法:
this.route.data.subscribe(params => {
console.log("params", params.key);
});
const key = this.route.snapshot.params[‘key‘];
console.log("key", key);
