本篇文章给大家带来的内容是关于php队列实现的代码示例，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
onSameUrlNavigation
从angular5.1起提供onSameUrlNavigation来支持路由重新加载。、
有两个值'reload'和'ignore'。默认为'ignore'
定义当路由器收到一个导航到当前 URL 的请求时应该怎么做。 默认情况下，路由器将会忽略这次导航。但这样会阻止类似于 "刷新" 按钮的特性。 使用该选项可以配置导航到当前 URL 时的行为。
使用
配置onSameUrlNavigation@NgModule({
imports: [RouterModule.forRoot(
routes,
{ onSameUrlNavigation: 'reload' }
)],
exports: [RouterModule]
})
reload实际上不会重新加载路由，只是重新出发挂载在路由器上的事件。
配置runGuardsAndResolvers
runGuardsAndResolvers有三个值：paramsChange: 仅在路由参数更改时触发。如/reports/:id 中id更改
paramsOrQueryParamsChange: 当路由参数更改或参训参数更改时触发。如/reports/:id/list?page=23中的id或page属性更改
always ：始终触发const routes: Routes = [
{
path: '',
children: [
{ path: 'report-list', component: ReportListComponent },
{ path: 'detail/:id', component: ReportDetailComponent, runGuardsAndResolvers: 'always' },
{ path: '', redirectTo: 'report-list', pathMatch: 'full' }
]
}
];
组件监听router.eventsimport {Component, OnDestroy, OnInit} from '@angular/core';
import {Observable} from 'rxjs';
import {Report} from '@models/report';
import {ReportService} from '@services/report.service';
import {ActivatedRoute, NavigationEnd, Router} from '@angular/router';
@Component({
selector: 'app-report-detail',
templateUrl: './report-ponent.html',
styleUrls: ['./report-ponent.scss']
})
export class ReportDetailComponent implements OnInit, OnDestroy {
report$: Observable;
navigationSubscription;
constructor(
private reportService: ReportService,
private router: Router,
private route: ActivatedRoute
) {
this.navigationSubscription = this.router.events.subscribe((event: any) => {
if (event instanceof NavigationEnd) {
this.initLoad(event);
}
});
}
ngOnInit() {
const id = +this.route.snapshot.paramMap.get('id');
this.report$ = this.reportService.getReport(id);
}
ngOnDestroy(): void {
// 销毁navigationSubscription，避免内存泄漏
if (this.navigationSubscription) {
this.navigationSubscription.unsubscribe();
}
}
initLoad(e) {
window.scrollTo(0, 0);
console.log(e);
}
}
