在父视图中,我有一个mat-button-toggle-group,用于在网格和列表布局之间切换。网格布局使用router-outlet显示子组件<router-outlet></router-outlet>
,但列表布局使用选择器<child-view [child]="childItem"></child-view>
直接实现子组件。
gird和list html都在同一个父html文件中,但是通过检查viewStyle
变量来显示。当按下mat-button-toggle-group按钮时,新的viewStyle被设置并作为查询参数传递;路线被导航回原始父视图,没有参数,只查询参数 - this.router.navigate([this.parentName],{ queryParams: { viewStyle: this.viewStyle }});
。
因此,在网格视图中,当您单击子元素时,它会激活路由器链接并正确显示信息。然后,如果单击列表视图,它将取消激活路由器链接并正确切换。问题是当您单击返回网格链接时,路由器插座会自动激活,并且显示屏中将显示要选择的最后一个子节点。
当viewStyle发生变化或是否有其他方式来路由页面时,有没有办法重置路由器插座?
编辑: 组织(父)有多个存储库(子)...我想在网格和列表视图中显示存储库。单击网格视图中的repo时,它会显示右侧的信息,并将repo名称添加到URL。列表视图只是mat-expansion-panels,当你单击它时,它会扩展为存储库视图选择器组件。
路由
const appRoutes: Routes = [
{
path: ':orgName',
component: OrganizationViewComponent,
children:[
{
path: ':repoName',
component: RepositoryViewComponent,
},

component.ts
viewChange(event: any) {
this.viewStyle = event.value;
this.openRepos = [];
this.currentrepo = null;
this.router.navigate([this.orgName, {
outlets: { primary: null }
}], { queryParams: this.getQueryParams() })
}
答案 0 :(得分:0)
试试这个
this.router.navigate([this.parentName, {
outlets: {
primary: null
}
}], { queryParams: { viewStyle: this.viewStyle } })
