Snackbar 消息条
Snackbars provide brief messages about app processes. The component is also known as a toast.
消息条 将应用程序已执行或即将执行的进程通知用户。 它们会从屏幕底部短暂地出现。 它们不应中断用户体验,也不要求任何用户的操作来关闭。
Snackbars contain a single line of text directly related to the operation performed. They may contain a text action, but no icons. You can use them to display notifications.
频率
我们规定一次只能显示一个消息条。
简单的消息条
一个简单的消息条旨在重现谷歌 Keep 消息条的行为。
自定义的消息条
以下是自定义组件的一些例子。 您可以在重写文档页中了解有关此内容的更多信息。
<Button variant="outlined" onClick={handleClick}>
Open success snackbar
</Button>
<Snackbar open={open} autoHideDuration={6000} onClose={handleClose}>
<Alert onClose={handleClose} severity="success">
This is a success message!
</Alert>
</Snackbar>
<Alert severity="error">This is an error message!</Alert>
<Alert severity="warning">This is a warning message!</Alert>
<Alert severity="info">This is an information message!</Alert>
<Alert severity="success">This is a success message!</Alert>
<SnackbarContent message="I love snacks." action={action} />
<SnackbarContent
message={
'I love candy. I love cookies. I love cupcakes. \
I love cheesecake. I love chocolate.'
}
/>
<SnackbarContent message="I love candy. I love cookies. I love cupcakes." action={action} />
<SnackbarContent
message={
'I love candy. I love cookies. I love cupcakes. \
I love cheesecake. I love chocolate.'
}
action={action}
/>
更改过渡动画
Grow是默认的过渡动画但你可以使用不同的过渡动画。
<Button onClick={handleClick(GrowTransition)}>Grow Transition</Button>
<Button onClick={handleClick(Fade)}>Fade Transition</Button>
<Button onClick={handleClick(SlideTransition)}>Slide Transition</Button>
<Snackbar
open={state.open}
onClose={handleClose}
TransitionComponent={state.Transition}
message="I love snacks"
/>
控制滑动的方向
你可以修改 Slide 过渡的方向 。
<Button onClick={handleClick(TransitionLeft)}>Right</Button>
<Button onClick={handleClick(TransitionUp)}>Up</Button>
<Button onClick={handleClick(TransitionRight)}>Left</Button>
<Button onClick={handleClick(TransitionDown)}>Down</Button>
<Snackbar
open={open}
onClose={handleClose}
TransitionComponent={transition}
message="I love snacks"
/>
补充项目
对于更高级的用例,您可以利用:
notistack
This example demonstrates how to use notistack. notistack has an imperative API that makes it easy to display snackbars, without having to handle their open/close state. It also enables you to stack them on top of one another (although this is discouraged by the Material Design specification).
可访问性
(WAI-ARIA: https://www.w3.org/TR/wai-aria-1.1/#alert)
- By default, the snackbar won't auto-hide. However, if you decide to use the
autoHideDuration
prop, it's recommended to give the user sufficient time to respond.
