Angular刷新当前页面的实现方法
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
constroutes: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.events
import{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-detail.component.html',
styleUrls:['./report-detail.component.scss']
})
exportclassReportDetailComponentimplementsOnInit,OnDestroy{
report$:Observable;
navigationSubscription;
constructor(
privatereportService:ReportService,
privaterouter:Router,
privateroute:ActivatedRoute
){
this.navigationSubscription=this.router.events.subscribe((event:any)=>{
if(eventinstanceofNavigationEnd){
this.initLoad(event);
}
});
}
ngOnInit(){
constid=+this.route.snapshot.paramMap.get('id');
this.report$=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);
}
}
