[英]How to trigger loading animation from a loading action in react/redux
[英]react redux how to trigger container function with action coming from non react component
我有一個通過單擊非反應組件觸發的登錄對話框的模式。
當單擊非反應組件時,我設法調度了動作並更新了狀態,因此該信息在props上可用,但是我需要觸發一個更新CSS之類的函數,並且無法在容器內進行操作。
如果操作是來自容器或其子級的,那將是微不足道的。
因此,在下面的app.js代碼上,無論何時調度SHOW_LOGIN操作,我都嘗試觸發onLoginClick()方法。
另外,應該使用同一onLoginClick()方法上的SHOW_LOGIN的有效負載來更新this.state.message。
Redux的store.subscriber()方法是在狀態更改時觸發的,但是我找不到在這種情況下如何使它工作的方法。
首先,它僅在上游組件上可用,然后我仍然無法從store.subscriber觸發onLoginClick()方法。
謝謝
