当我尝试用html调用dashboard.all_interviewed时,我从错误TypeError中收到错误:“ _ co.dashboard未定义”。
在“我的dashboard.component.ts”中
dashboard: Dashboard;
getDashboard() {
this.dashboardService.getDashboard().subscribe(
res => {
this.dashboard = res;
}
)
}
在Dasboard课上
export class Dashboard {
all_interviewed: number;
}
dashboard.component.html
<h2>{{ dashboard.all_interviewed }} </h2>
我在控制台日志中收到此错误。
错误TypeError:“ _ co.dashboard未定义” View_DashboardComponent_0 DashboardComponent.html:208 角度32 RxJS 5 Angular 8 DashboardComponent.html:203:11

<h2>{{ dashboard.all_interviewed }}</h2>
</div>
