我有一个组件从订阅商店获取其数据.
this.store.select('somedata').subscribe((state: any) => {
this.somedata = state.data;
});
我想在组件不再使用时取消订阅此订阅,在我订阅某些observable的其他地方,如下所示：
this.service.data.subscribe(
(result: any) => {//data}
);
我在ngOnOnDestroy上取消订阅,如下所示：
ngOnDestroy(){
this.service.data.unsubscribe();
}
但是对于商店我无法做到,它给了我错误：
Property 'unsubscribe' does not exist on type 'Store<State>'
订阅时,您将收到订阅对象,您可以调用unsubscribe()
原文链接：https://www.f2er.com/angularjs/141697.htmlconst subscription = this.store.select('somedata').subscribe((state: any) => {
this.somedata = state.data;
});
// later
subscription.unsubscribe();
要么
ngOnInit(){
this.someDataSubscription = this.store.select('somedata').subscribe((state: any) => {
this.somedata = state.data;
});
}
ngOnDestroy(){
this.someDataSubscription.unsubscribe();
}
