我遇到了这个奇怪的问题，这是我第一次遇到它。我创建了一个使用 Redux 工具包处理应用程序创建的按钮。根据 UI 设计，按钮应该在如下所示的页面上出现两次。突出显示的按钮是同一组件。
如果我尝试创建一个应用程序，它会显示两条 toast 消息：
我注意到，如果我删除“创建应用程序”按钮之一并保留一个，然后我尝试创建一个仅显示一条 Toast 消息的应用程序，如预期的那样。
创建 2 个单独的按钮来处理一项功能是理想的最佳做法吗？
这是 CreateAnApp 按钮：

我通过将 toast 消息函数从“创建应用程序”中的 useEffect 挂钩移动到“应用程序”页面来修复此问题。刚刚在厕所里想出来的哈哈。我无法对此进行更多阐述，因为我还没有完全理解它。我们每天都在学习
更新了“创建应用程序”按钮中的 useEffect 挂钩：
useEffect(() => {
if (isError) {
dispatch(reset());
}
if (isAppSuccess) {
dispatch(reset());
onClose();
}
}, [isAppSuccess]);
更新的应用程序页面：
useEffect(() => {
if (isError) {
toast({
title: "Error",
description: message,
status: "error",
position: "top-right",
duration: 5000,
isClosable: true,
});
}
if (isAppSuccess) {
toast({
title: "App created",
description: "Refreshing page",
status: "success",
position: "top-right",
duration: 5000,
isClosable: true,
});
}
}, [isAppSuccess]);
