在模态框的默认插槽中使用按钮或任何其他组件。
然后,使用#content插槽来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>
你还可以使用#header、#body和#footer插槽来自定义模态框的内容。
使用title属性来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>
使用description属性来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>
使用close属性来自定义或隐藏模态框头部显示的关闭按钮(设置为false)。
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,因为它是头部的一部分。使用 close-icon 属性自定义关闭按钮的 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>
使用overlay属性控制模态框是否具有覆盖层。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>
使用transition属性控制模态框是否带有动画。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>
使用fullscreen属性使模态框全屏。
<template>
<UModal fullscreen title="Modal fullscreen">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-full" />
</template>
</UModal>
</template>
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,你可以通过按O键来切换模态框。将dismissible属性设置为false可防止模态框在点击外部或按Escape键时关闭。当用户尝试关闭模态框时,将发出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>
你可以使用useOverlay组合式函数以编程方式打开模态框。
App组件包装您的应用程序,该组件使用了OverlayProvider组件的任何属性。首先,创建一个将以编程方式打开的模态组件
<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。你可以通过close事件发出任何数据,但是,必须发出该事件才能捕获返回值。然后,在你的应用中使用它
<script setup lang="ts">
import { LazyModalExample } from '#components'
const count = ref(0)
const toast = useToast()
const overlay = useOverlay()
const modal = overlay.create(LazyModalExample)
async function open() {
const instance = modal.open({
count: count.value
})
const shouldIncrement = await instance.result
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: ${shouldIncrement}`,
color: 'error',
id: 'modal-dismiss'
})
}
</script>
<template>
<UButton label="Open" color="neutral" variant="subtle" @click="open" />
</template>
emit('close')在模态组件内关闭模态框。你可以在模态框中嵌套模态框。
<script setup lang="ts">
const first = ref(false)
const second = ref(false)
</script>
<template>
<UModal v-model:open="first" title="First modal" :ui="{ footer: 'justify-end' }">
<UButton color="neutral" variant="subtle" label="Open" />
<template #footer>
<UButton label="Close" color="neutral" variant="outline" @click="first = false" />
<UModal v-model:open="second" title="Second modal" :ui="{ footer: 'justify-end' }">
<UButton label="Open second" color="neutral" />
<template #footer>
<UButton label="Close" color="neutral" variant="outline" @click="second = false" />
</template>
</UModal>
</template>
</UModal>
</template>
使用#footer插槽在模态框主体后添加内容。
<script setup lang="ts">
const open = ref(false)
</script>
<template>
<UModal v-model:open="open" title="Modal with footer" description="This is useful when you want a form in a Modal." :ui="{ footer: 'justify-end' }">
<UButton label="Open" color="neutral" variant="subtle" />
<template #body>
<Placeholder class="h-48" />
</template>
<template #footer="{ close }">
<UButton label="Cancel" color="neutral" variant="outline" @click="close" />
<UButton label="Submit" color="neutral" />
</template>
</UModal>
</template>
你可以在模态框内容中嵌套命令面板组件。
<script setup lang="ts">
const searchTerm = ref('')
const { data: users, status } = await useFetch('https://jsonplaceholder.typicode.com/users', {
key: 'command-palette-users',
params: { q: searchTerm },
transform: (data: { id: number, name: string, email: string }[]) => {
return data?.map(user => ({ id: user.id, label: user.name, suffix: user.email, avatar: { src: `https://i.pravatar.cc/120?img=${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>
