目前我有三个不同的模块:
现在在这个玩家搜索模块中我有一个玩家搜索结果comp与子组件。其中一个子comp是一个带有列表的模态。如果我点击此列表项(播放器),它应该导航'到父comp.and更新其视图。但唯一更新的是网址。 window.location.href(url)有一种解决方法,可在导航方法更新网址后重新关联页面。但我不喜欢解决方法。
父母比赛。几乎看起来像:
export class PlayerSearchResultComponent implements OnInit, AfterViewInit {
public isLoading = true;
public searchValue: string;
public playerResult: PlayerByPlayerTagType;
public hasNoResultFound = false;
public clanInfo: ClansByClantagType;
constructor(private playerSearchService: PlayerSearchService,
private activatedRoute: ActivatedRoute,
private clanSearchService: ClanSearchService) {
}
ngOnInit(): void {
this.activatedRoute.params.subscribe((params: Params) => {
this.searchValue = params['playerId'];
});
}
ngAfterViewInit() {
this.playerSearchService.getPlayerByPlayerTag(this.searchValue).subscribe(player => {
this.playerResult = player;
if (!isUndefined(this.playerResult.clan)) {
this.clanSearchService.getClanByClanTag(this.playerResult.clan.tag).subscribe((data: ClansByClantagType) => {
this.clanInfo = data;
});
}
}, () => {
this.hasNoResultFound = true;
this.isLoading = false;
},
() => this.isLoading = false);
}
}
孩子补:
export class ClanModalComponent {
@ViewChild('childModal') childModal: ModalDirective;
@Input() playerResult: PlayerByPlayerTagType;
@Input() clanInfo: ClansByClantagType;
constructor(private router: Router) {
}
open() {
this.childModal.show();
}
memberSearch(member) {
this.childModal.hide();
this.router.navigate(['search/' + member.tag]);
}
}
播放器结果模块如下所示:
const appRoutes: Routes = [
{path: 'search/:playerId', component: PlayerSearchResultComponent}
];
@NgModule({
declarations: [
...
],
imports: [
...
RouterModule.forChild(
appRoutes
)],
providers: [
...
],
exports: []
})
export class PlayerResultModule {
}

因此,要根据路由参数加载,您必须订阅Route params并加载数据。不会再次处理ngAfterViewInit。因为路线改变后组件不会再次加载!
ngOnInit(): void {
this.activatedRoute.params.subscribe((params: Params) => {
this.searchValue = params['playerId'];
this.playerSearchService
.getPlayerByPlayerTag(this.searchValue)
.subscribe(player => {
this.playerResult = player;
...
...
});
}
}

//browser is already on /pathName/oldID,
//this means our Routes are correct
let newLocation = `/pathName/${newID}`;
// override default re-use strategy
this.router
.routeReuseStrategy
.shouldReuseRoute = function () {
return false;
};
this.router
.navigateByUrl(newLocation)
.then(
(worked) => {
//works only because we hooked
//the routeReuseStrategy.shouldReuseRoute above
},
(error) => {
debugger;
}
);
我看到这个问题的次数比我想承认的要多,通常当我有一个父容器重用子组件时才会见到。
这是因为Angular的默认路由重用策略不会重新加载页面!
上面的代码修复了此默认行为,但必须放入适当的组件中才能从头开始行为进行重新加载。
请注意,还有其他选择...假设您要保持组件重用的速度。在这种情况下,只需在已加载的组件中提供一个入口点即可重置数据,而使组件通过changeDetectorRef.DetectChanges()进行更改。
