如何解决基于条件的路由器插座不会在 angular 的 app.component.html 中的 url 更改时更改其内容
在 app.component.html 中,有基于条件的模板.. 我的问题是 ngif 中的条件匹配(但 url 更改),然后路由器插座不更改其内容,但如果条件不匹配,则内容更改。 下面是我的代码
app.component.html
<app-web-header></app-web-header>
<div *ngIf="isAdminComponent">
<app-home ></app-home>
</div>
<div *ngIf="!isAdminComponent">
<app-user-home></app-user-home>
</div>
<app-web-footer></app-web-footer>
app.component.ts
import { Component,Inject } from '@angular/core';
import{ GlobalConstants } from './common/global-constants';
import { first } from 'rxjs/operators';
import { User } from './data/schema/user';
import { UserService } from './data/service/user.service';
import { AuthenticationService } from './data/service/authentication.service';
import { Role } from './data/schema/role';
import { Router } from '@angular/router';
import {LOCAL_STORAGE,WebStorageService} from 'angular-webstorage-service';
@Component({
selector: 'app-root',templateUrl: './app.component.html',styleUrls: ['./app.component.css']
})
export class AppComponent {
title = GlobalConstants.siteTitle;
public data:any=[];
public href: string = "";
loading = false;
user: User;
userFromApi: User;
isadminComponent=false;
constructor(
private userService: UserService,private authenticationService: AuthenticationService,private router :Router){
this.user = this.authenticationService.userValue;
this.authenticationService.user.subscribe(x => this.user = x);
}
ngOnInit() {
this.isadminComponent=false;
this.router.navigate([{outlets: {primary: this.href }}]);
this.loading = true;
this.userService.getById(this.user.id).pipe(first()).subscribe(user => {
this.loading = false;
this.userFromApi = user;
});
}
get isAdmin() {
// localStorage.setItem('isLoggedIn',"true");
// localStorage.setItem('role',Role.Admin);
return this.user && this.user.role === Role.Admin;
}
get isAdminComponent(){
this.href = this.router.url;
console.log("href "+this.href);
if(this.href.includes("/admin/")){
// this.router.navigateByUrl(this.href);
return this.isadminComponent=true;}
else return this.isadminComponent=false;
}
logout() {
this.authenticationService.logout();
}
collapsed = true;
}
我为用户和管理员制作了不同的模板,并希望在该模板中显示内容, 问题是,如果 url 包含 admin,那么它第一次可以完美运行,但是如果我再次尝试在 admin 组件上导航,则 url 会更改但内容保持不变,除非我重新加载页面, 但用户组件工作正常
