用法
在模态框的默认插槽中使用 Button 或任何其他组件。
然后,使用 #content
插槽添加模态框打开时显示的内容。
<template>
<UModal>
<UButton label="Open" color="neutral" variant="subtle" />
<template #content>
<Placeholder class="h-48 m-4" />
</template>
</UModal>
</template>
您也可以使用 #header
、#body
和 #footer
插槽来自定义模态框的内容。
标题
使用 title
prop 设置模态框头部的标题。
<template>
<UModal title="Modal with title">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
</UModal>
</template>
描述
使用 description
prop 设置模态框头部的描述。
<template>
<UModal
title="Modal with description"
description="Lorem ipsum dolor sit amet, consectetur adipiscing elit."
>
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
</UModal>
</template>
关闭
使用 close
prop 来自定义或隐藏模态框头部显示的关闭按钮(当值为 false
时)。
您可以传递 Button 组件的任何属性来自定义它。
<template>
<UModal
title="Modal with close button"
:close="{
color: 'primary',
variant: 'outline',
class: 'rounded-full'
}"
>
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
</UModal>
</template>
#content
插槽,则不会显示关闭按钮,因为它属于头部的一部分。关闭图标
使用 close-icon
prop 来自定义关闭按钮的 图标。默认为 i-lucide-x
。
<template>
<UModal title="Modal with close button" close-icon="i-lucide-arrow-right">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
</UModal>
</template>
覆盖层
使用 overlay
prop 控制模态框是否显示覆盖层。默认为 true
。
<template>
<UModal :overlay="false" title="Modal without overlay">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
</UModal>
</template>
过渡
使用 transition
prop 控制模态框是否启用过渡动画。默认为 true
。
<template>
<UModal :transition="false" title="Modal without transition">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
</UModal>
</template>
全屏
使用 fullscreen
prop 使模态框全屏显示。
<template>
<UModal fullscreen title="Modal fullscreen">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-full" />
</template>
</UModal>
</template>
示例
控制打开状态
您可以通过使用 default-open
prop 或 v-model:open
指令来控制打开状态。
<script setup lang="ts">
const open = ref(false)
defineShortcuts({
o: () => open.value = !open.value
})
</script>
<template>
<UModal v-model:open="open">
<UButton label="Open" color="neutral" variant="subtle" />
<template #content>
<Placeholder class="h-48 m-4" />
</template>
</UModal>
</template>
defineShortcuts
,您可以按下 O 键来切换模态框的显示/隐藏状态。阻止关闭
将 dismissible
prop 设置为 false
可防止模态框在点击外部或按下 Escape 键时关闭。当用户尝试关闭时,将触发 close:prevent
事件。
<template>
<UModal :dismissible="false" title="Modal non-dismissible">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
</UModal>
</template>
编程式用法
您可以使用 useOverlay
可组合函数以编程式方式打开模态框。
App
组件包裹您的应用,App 组件使用了OverlayProvider
组件。首先,创建一个将以编程式方式打开的模态框组件
<script setup lang="ts">
defineProps<{
count: number
}>()
const emit = defineEmits<{ close: [boolean] }>()
</script>
<template>
<UModal
:close="{ onClick: () => emit('close', false) }"
:title="`This modal was opened programmatically ${count} times`"
>
<template #footer>
<div class="flex gap-2">
<UButton color="neutral" label="Dismiss" @click="emit('close', false)" />
<UButton label="Success" @click="emit('close', true)" />
</div>
</template>
</UModal>
</template>
close
事件。您可以通过 close
事件触发任何数据,但是,必须触发该事件才能捕获返回值。然后,在您的应用中使用它
<script setup lang="ts">
import { LazyModalExample } from '#components'
const count = ref(0)
const toast = useToast()
const overlay = useOverlay()
const modal = overlay.create(LazyModalExample, {
props: {
count: count.value
}
})
async function open() {
const shouldIncrement = await modal.open()
if (shouldIncrement) {
count.value++
toast.add({
title: `Success: ${shouldIncrement}`,
color: 'success',
id: 'modal-success'
})
// Update the count
modal.patch({
count: count.value
})
return
}
toast.add({
title: `Dismissed: ${shouldIncrement}`,
color: 'error',
id: 'modal-dismiss'
})
}
</script>
<template>
<UButton label="Open" color="neutral" variant="subtle" @click="open" />
</template>
emit('close')
来关闭模态框。嵌套模态框
您可以将模态框相互嵌套。
<script setup lang="ts">
const first = ref(false)
const second = ref(false)
</script>
<template>
<UModal v-model:open="first" title="First modal" :ui="{ footer: 'justify-end' }">
<UButton color="neutral" variant="subtle" label="Open" />
<template #footer>
<UButton label="Close" color="neutral" variant="outline" @click="first = false" />
<UModal v-model:open="second" title="Second modal" :ui="{ footer: 'justify-end' }">
<UButton label="Open second" color="neutral" />
<template #footer>
<UButton label="Close" color="neutral" variant="outline" @click="second = false" />
</template>
</UModal>
</template>
</UModal>
</template>
使用 footer 插槽
使用 #footer
插槽在模态框主体后添加内容。
<script setup lang="ts">
const open = ref(false)
</script>
<template>
<UModal v-model:open="open" title="Modal with footer" description="This is useful when you want a form in a Modal." :ui="{ footer: 'justify-end' }">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
<template #footer>
<UButton label="Cancel" color="neutral" variant="outline" @click="open = false" />
<UButton label="Submit" color="neutral" />
</template>
</UModal>
</template>
使用命令面板
您可以在模态框内容内部使用 CommandPalette 组件。
<script setup lang="ts">
const searchTerm = ref('')
const { data: users, status } = await useFetch('https://jsonplaceholder.typicode.com/users', {
key: 'command-palette-users',
params: { q: searchTerm },
transform: (data: { id: number, name: string, email: string }[]) => {
return data?.map(user => ({ id: user.id, label: user.name, suffix: user.email, avatar: { src: `https://i.pravatar.cc/120?img=${user.id}` } })) || []
},
lazy: true
})
const groups = computed(() => [{
id: 'users',
label: searchTerm.value ? `Users matching “${searchTerm.value}”...` : 'Users',
items: users.value || [],
ignoreFilter: true
}])
</script>
<template>
<UModal>
<UButton
label="Search users..."
color="neutral"
variant="subtle"
icon="i-lucide-search"
/>
<template #content>
<UCommandPalette
v-model:search-term="searchTerm"
:loading="status === 'pending'"
:groups="groups"
placeholder="Search users..."
class="h-80"
/>
</template>
</UModal>
</template>
