对话框

对话框是一个容器，用于在覆盖窗口中显示内容。

导入 # 


import Dialog from 'primevue/dialog';

基本 #

对话框用作容器，可见性通过与visible属性的绑定来控制。


<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>

模板 #

标头和页脚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>

位置 #

position属性定义相对于屏幕的位置。


<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>

可最大化 #

添加maximizable属性启用全屏模式。


<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>

长内容 #

当内容超出视窗时，对话框会自动变为可滚动。


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

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

无模态 #

对话框后面的蒙版层通过modal属性配置。默认情况下，不会添加蒙版层。


<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>

响应式 #

可以使用breakpoints选项根据屏幕尺寸调整对话框的宽度，其中断点的最大宽度和宽度定义为键值对。当没有断点匹配时，使用在style或class中定义的宽度。或者，还可以使用像 Tailwind 或 PrimeFlex 这样的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>

无头 #

通过定义一个container插槽来启用无头模式，这使您可以实现整个 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 }">

无障碍性 #

屏幕阅读器

对话框组件使用dialog角色以及引用标头元素的aria-labelledby，但是任何属性都传递到根元素，因此您可以使用aria-labelledby来覆盖此默认行为。此外，aria-modal被添加，因为焦点保留在弹出窗口中。

触发元素也需要aria-expanded和aria-controls显式处理。

关闭元素是一个带有aria-label的button，该标签默认情况下引用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>

覆盖层键盘支持

键功能
tab如果modal为 true，则将焦点移动到对话框中的下一个可聚焦元素。否则，将焦点移动到页面制表符顺序中的可聚焦元素。
shift + tab如果modal为 true，则将焦点移动到对话框中的上一个可聚焦元素。否则，将焦点移动到页面制表符顺序中的可聚焦元素。
escape如果closeOnEscape为 true，则关闭对话框。

关闭按钮键盘支持
