在一个13.4版本的Nextjs项目（app router）中，使用Typescript和TailwindCSS。
我正在尝试使用（不可思议的）shadcnUI库提供的toast。它的灵感来自于React热吐司，并带来了这个图书馆闻名的酱汁味道。
我对吐司功能的一般实现没有问题。然而，当我试图在每个吐司的底部添加一个计时器栏，显示祝酒词的持续时间时，事情发生了变化。我已经设法显示了计时器栏（一个自定义进度栏元素），并使其与每个吐司的持续时间相对应。
但是在这样做的时候，我注意到吐司的持续时间实际上不是我作为 prop 给它的，也不是通过shadcn组件的use-toast.ts中设置的TOAST_REMOVE_DELAY常量给出的。
我尝试了不同的设置，但似乎Toaster的默认值（由react-hot-toast中的根toaster提供）为5000 ms（5s），并且在实际Toast中作为 prop 传递的“duration”值不会覆盖它。至少这是我到目前为止所认为的。在对提供的代码进行了一点修改之后，我无法设法传递持续时间属性，并将其作为Toaster使用的唯一持续时间值（除非为null，则为默认值ofc）。
不管怎样，对于那些好心帮我的人...
下面是使用吐司：

我已经尝试了不同的选择：
- 直接设置吐司_REMOVE_DELAY常量（不影响烤面包持续时间）
- 在addToRemoveQueue的setTimeout中添加另一个计时器
const addToRemoveQueue = (toastId: string, delay: number) => {
if (toastTimeouts.has(toastId)) {
return
}
const timeout = setTimeout(() => {
console.log(new Date().toLocaleTimeString(), "REMOVE_TOAST:", toastId )
toastTimeouts.delete(toastId)
dispatch({
type: "REMOVE_TOAST",
toastId: toastId,
})
}, delay | TOAST_REMOVE_DELAY)
toastTimeouts.set(toastId, timeout)
}型
其中delay是一个传递吐司持续时间的常量，但似乎即使是基本的TOAST_REMOVE_DELAY也不会影响toast持续时间。它默认设置为1000000，但每次敬酒持续5000次。
- 我尝试添加另一个计时器来调用DISMISS_吐司操作，但这只适用于小于5s的时间，否则Toaster中的计时器似乎之前被触发过。
- 我甚至怀疑这可能是一个开发模式的问题，但我试图把它推向生产和行为是完全相同的。

按热度按时间wlzqhblo1#
显然我错过了在烤面包机 prop 持续时间的传递：

对于那些感兴趣的人，这里是其他文件更正：use-toast：

的字符串
如果你想测试它，不要忘记在RootLayout中添加Toaster作为ToastPrivider：
