您想要链接/HTML 还是要以命令方式/在代码中路由?
链接:RouterLink 指令始终将提供的链接视为当前 URL 的增量:
[routerLink]="['/absolute']"
[routerLink]="['../../parent']"
[routerLink]="['../sibling']"
[routerLink]="['./child']" // or
[routerLink]="['child']"
// with route param ../../parent;abc=xyz
[routerLink]="['../../parent', {abc: 'xyz'}]"
// with query param and fragment ../../parent?p1=value1&p2=v2#frag
[routerLink]="['../../parent']" [queryParams]="{p1: 'value', p2: 'v2'}" fragment="frag"
使用RouterLink,记得导入和使用directives数组:
import { ROUTER_DIRECTIVES } from '@angular/router';
@Component({
directives: [ROUTER_DIRECTIVES],
命令式:navigate() 方法需要一个起点(即relativeTo 参数)。如果没有提供,导航是绝对的:
import { Router, ActivatedRoute } from '@angular/router';
...
constructor(private router: Router, private route: ActivatedRoute) {}
...
this.router.navigate(["/absolute/path"]);
this.router.navigate(["../../parent"], {relativeTo: this.route});
this.router.navigate(["../sibling"], {relativeTo: this.route});
this.router.navigate(["./child"], {relativeTo: this.route}); // or
this.router.navigate(["child"], {relativeTo: this.route});
// with route param ../../parent;abc=xyz
this.router.navigate(["../../parent", {abc: 'xyz'}], {relativeTo: this.route});
// with query param and fragment ../../parent?p1=value1&p2=v2#frag
this.router.navigate(["../../parent"], {relativeTo: this.route,
queryParams: {p1: 'value', p2: 'v2'}, fragment: 'frag'});
// navigate without updating the URL
this.router.navigate(["../../parent"], {relativeTo: this.route, skipLocationChange: true});
