对话框

对话框是一个在覆盖窗口中显示内容的容器。


import Dialog from 'primevue/dialog';

对话框用作容器,可见性通过绑定到visible属性来控制。


<Button label="Show" @click="visible = true" />

<Dialog v-model:visible="visible" modal header="Edit Profile" :style="{ width: '25rem' }">
    <span class="text-surface-500 dark:text-surface-400 block mb-8">Update your information.</span>
    <div class="flex items-center gap-4 mb-4">
        <label for="username" class="font-semibold w-24">Username</label>
        <InputText id="username" class="flex-auto" autocomplete="off" />
    </div>
    <div class="flex items-center gap-4 mb-8">
        <label for="email" class="font-semibold w-24">Email</label>
        <InputText id="email" class="flex-auto" autocomplete="off" />
    </div>
    <div class="flex justify-end gap-2">
        <Button type="button" label="Cancel" severity="secondary" @click="visible = false"></Button>
        <Button type="button" label="Save" @click="visible = false"></Button>
    </div>
</Dialog>

头部和尾部部分允许通过模板进行自定义。


<Button label="Show" @click="visible = true" />

<Dialog v-model:visible="visible" modal header="Edit Profile" :style="{ width: '25rem' }">
    <template #header>
        <div class="inline-flex items-center justify-center gap-2">
            <Avatar image="https://primefaces.org/cdn/primevue/images/avatar/amyelsner.png" shape="circle" />
            <span class="font-bold whitespace-nowrap">Amy Elsner</span>
        </div>
    </template>
    <span class="text-surface-500 dark:text-surface-400 block mb-8">Update your information.</span>
    <div class="flex items-center gap-4 mb-4">
        <label for="username" class="font-semibold w-24">Username</label>
        <InputText id="username" class="flex-auto" autocomplete="off" />
    </div>
    <div class="flex items-center gap-4 mb-2">
        <label for="email" class="font-semibold w-24">Email</label>
        <InputText id="email" class="flex-auto" autocomplete="off" />
    </div>
    <template #footer>
        <Button label="Cancel" text severity="secondary" @click="visible = false" autofocus />
        <Button label="Save" outlined severity="secondary" @click="visible = false" autofocus />
    </template>
</Dialog>

position属性定义了相对于屏幕的位置。


<div class="flex flex-wrap justify-center gap-2 mb-2">
    <Button label="Left" icon="pi pi-arrow-right" @click="openPosition('left')" severity="secondary" style="min-width: 10rem" />
    <Button label="Right" icon="pi pi-arrow-left" @click="openPosition('right')" severity="secondary" style="min-width: 10rem" />
</div>
<div class="flex flex-wrap justify-center gap-2 mb-2">
    <Button label="TopLeft" icon="pi pi-arrow-down-right" @click="openPosition('topleft')" severity="secondary" style="min-width: 10rem" />
    <Button label="Top" icon="pi pi-arrow-down" @click="openPosition('top')" severity="secondary" style="min-width: 10rem" />
    <Button label="TopRight" icon="pi pi-arrow-down-left" @click="openPosition('topright')" severity="secondary" style="min-width: 10rem" />
</div>
<div class="flex flex-wrap justify-center gap-2">
    <Button label="BottomLeft" icon="pi pi-arrow-up-right" @click="openPosition('bottomleft')" severity="secondary" style="min-width: 10rem" />
    <Button label="Bottom" icon="pi pi-arrow-up" @click="openPosition('bottom')" severity="secondary" style="min-width: 10rem" />
    <Button label="BottomRight" icon="pi pi-arrow-up-left" @click="openPosition('bottomright')" severity="secondary" style="min-width: 10rem" />
</div>

<Dialog v-model:visible="visible" header="Edit Profile" :style="{ width: '25rem' }" :position="position" :modal="true" :draggable="false">
    <span class="text-surface-500 dark:text-surface-400 block mb-8">Update your information.</span>
    <div class="flex items-center gap-4 mb-4">
        <label for="username" class="font-semibold w-24">Username</label>
        <InputText id="username" class="flex-auto" autocomplete="off" />
    </div>
    <div class="flex items-center gap-4 mb-8">
        <label for="email" class="font-semibold w-24">Email</label>
        <InputText id="email" class="flex-auto" autocomplete="off" />
    </div>
    <div class="flex justify-end gap-2">
        <Button type="button" label="Cancel" severity="secondary" @click="visible = false"></Button>
        <Button type="button" label="Save" @click="visible = false"></Button>
    </div>
</Dialog>

添加maximizable属性可以启用全屏模式。


<Button label="Show" @click="visible = true" />

<Dialog v-model:visible="visible" maximizable modal header="Header" :style="{ width: '50rem' }" :breakpoints="{ '1199px': '75vw', '575px': '90vw' }">
    <p class="m-0">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
    </p>
</Dialog>

当内容超出视口时,对话框会自动变为可滚动的。


<Button label="Show" @click="visible = true" />

<Dialog v-model:visible="visible" modal header="Header" :style="{ width: '50rem' }" :breakpoints="{ '1199px': '75vw', '575px': '90vw' }">

对话框后面的遮罩层通过modal属性进行配置。默认情况下,不添加模态层。


<Button label="Show" @click="visible = true" />

<Dialog v-model:visible="visible" header="Edit Profile" :style="{ width: '25rem' }">
    <span class="text-surface-500 dark:text-surface-400 block mb-8">Update your information.</span>
    <div class="flex items-center gap-4 mb-4">
        <label for="username" class="font-semibold w-24">Username</label>
        <InputText id="username" class="flex-auto" autocomplete="off" />
    </div>
    <div class="flex items-center gap-4 mb-8">
        <label for="email" class="font-semibold w-24">Email</label>
        <InputText id="email" class="flex-auto" autocomplete="off" />
    </div>
    <div class="flex justify-end gap-2">
        <Button type="button" label="Cancel" severity="secondary" @click="visible = false"></Button>
        <Button type="button" label="Save" @click="visible = false"></Button>
    </div>
</Dialog>

可以使用breakpoints选项根据屏幕尺寸调整对话框宽度,其中断点的最大宽度和宽度定义为键值对。当没有匹配的断点时,将使用在styleclass中定义的宽度。或者,也可以使用 Tailwind 或 PrimeFlex 等库的响应式实用程序类,例如md:w-screen


<Button label="Show" @click="visible = true" />

<Dialog v-model:visible="visible" modal header="Header" :style="{ width: '50vw' }" :breakpoints="{ '1199px': '75vw', '575px': '90vw' }">
    <p class="m-0">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
    </p>
</Dialog>

通过定义一个container插槽启用无头模式,该插槽允许您实现整个 UI 而不是默认元素。


<Button label="Login" icon="pi pi-user" @click="visible = true" />

<Dialog v-model:visible="visible" pt:root:class="!border-0 !bg-transparent" pt:mask:class="backdrop-blur-sm">
    <template #container="{ closeCallback }">
        <div class="flex flex-col px-8 py-8 gap-6 rounded-2xl" style="background-image: radial-gradient(circle at left top, var(--p-primary-400), var(--p-primary-700))">

屏幕阅读器

对话框组件使用dialog角色以及引用标题元素的aria-labelledby,但是任何属性都会传递到根元素,因此您可以使用aria-labelledby来覆盖此默认行为。此外,由于焦点保持在弹出窗口内,因此添加了aria-modal

触发元素还需要显式处理aria-expandedaria-controls

关闭元素是一个带有aria-labelbutton,默认情况下,它引用locale API 的aria.close属性,您可以使用closeButtonProps自定义元素并覆盖默认的aria-label


<Button label="Show" icon="pi pi-external-link" @click="visible = true" :aria-controls="visible ? 'dlg' : null" :aria-expanded="visible ? true : false" />

<Dialog id="dlg" header="Header" v-model:visible="visible" :style="{ width: '50vw' }">
    <p>Content</p>
</Dialog>

覆盖键盘支持

shift + tab如果modal为 true,则将焦点移动到对话框内的上一个可聚焦元素。否则,移动到页面选项卡序列中的可聚焦元素。
