Modal 对话框
模态对话框。
何时使用
需要用户处理事务,又不希望跳转页面以致打断工作流程时,可以使用 Modal 在当前页面正中打开一个浮层,承载相应的操作。
另外当需要一个简洁的确认框询问用户时,可以使用 Modal.confirm() 等语法糖方法。
基本用法
第一个对话框。
<template>
<div>
<g-button type="primary" @click="showModal">Open Modal</g-button>
<g-modal
v-model:visible="visible"
title="Basic Modal"
@ok="handleOk"
>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
</g-modal>
</div>
</template>
<script>
import { ref } from 'vue'
export default {
setup() {
const visible = ref(false)
const showModal = () => {
visible.value = true
}
const handleOk = (e) => {
console.log(e)
visible.value = false
}
return {
visible,
showModal,
handleOk
}
}
}
</script>异步关闭
点击确定后异步关闭对话框,例如提交表单。
<template>
<div>
<g-button type="primary" @click="showModal">Open Modal with async logic</g-button>
<g-modal
v-model:visible="visible"
title="Title"
:confirm-loading="confirmLoading"
@ok="handleOk"
@cancel="handleCancel"
>
<p>{{ modalText }}</p>
</g-modal>
</div>
</template>
<script>
import { ref } from 'vue'
export default {
setup() {
const visible = ref(false)
const confirmLoading = ref(false)
const modalText = ref('Content of the modal')
const showModal = () => {
visible.value = true
}
const handleOk = () => {
modalText.value = 'The modal will be closed after two seconds'
confirmLoading.value = true
setTimeout(() => {
visible.value = false
confirmLoading.value = false
}, 2000)
}
const handleCancel = () => {
console.log('Clicked cancel button')
visible.value = false
}
return {
visible,
confirmLoading,
modalText,
showModal,
handleOk,
handleCancel
}
}
}
</script>自定义页脚
更复杂的例子,自定义了页脚的按钮,点击提交后进入 loading 状态,完成后关闭。
不需要默认确定取消按钮时,你可以把 footer 设为 null。
<template>
<div>
<g-button type="primary" @click="showModal">Open Modal with customized footer</g-button>
<g-modal
v-model:visible="visible"
title="Title"
@cancel="handleCancel"
>
<template #footer>
<g-button key="back" @click="handleCancel">Return</g-button>
<g-button
key="submit"
type="primary"
:loading="loading"
@click="handleOk"
>
Submit
</g-button>
</template>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
</g-modal>
</div>
</template>
<script>
import { ref } from 'vue'
export default {
setup() {
const visible = ref(false)
const loading = ref(false)
const showModal = () => {
visible.value = true
}
const handleOk = () => {
loading.value = true
setTimeout(() => {
loading.value = false
visible.value = false
}, 3000)
}
const handleCancel = () => {
visible.value = false
}
return {
visible,
loading,
showModal,
handleOk,
handleCancel
}
}
}
</script>确认对话框
使用 confirm() 可以快捷地弹出确认框。onCancel/onOk 返回 promise 可以延迟关闭。
<template>
<div>
<g-button @click="showConfirm">Confirm</g-button>
<g-button @click="showPromiseConfirm" type="dashed">
With promise
</g-button>
<g-button @click="showDeleteConfirm" type="dashed">
Delete
</g-button>
<g-button @click="showPropsConfirm" type="dashed">
With extra props
</g-button>
</div>
</template>
<script>
import { Modal } from '@/components'
import { ExclamationCircleOutlined } from '@ant-design/icons-vue'
import { createVNode } from 'vue'
export default {
setup() {
const showConfirm = () => {
Modal.confirm({
title: 'Do you Want to delete these items?',
icon: createVNode(ExclamationCircleOutlined),
content: 'Some descriptions',
onOk() {
console.log('OK')
},
onCancel() {
console.log('Cancel')
},
})
}
const showPromiseConfirm = () => {
Modal.confirm({
title: 'Do you want to delete these items?',
icon: createVNode(ExclamationCircleOutlined),
content: 'When clicked the OK button, this dialog will be closed after 1 second',
onOk() {
return new Promise((resolve, reject) => {
setTimeout(Math.random() > 0.5 ? resolve : reject, 1000)
}).catch(() => console.log('Oops errors!'))
},
onCancel() {},
})
}
const showDeleteConfirm = () => {
Modal.confirm({
title: 'Are you sure delete this task?',
icon: createVNode(ExclamationCircleOutlined),
content: 'Some descriptions',
okText: 'Yes',
okType: 'danger',
cancelText: 'No',
onOk() {
console.log('OK')
},
onCancel() {
console.log('Cancel')
},
})
}
const showPropsConfirm = () => {
Modal.confirm({
title: 'Are you sure delete this task?',
icon: createVNode(ExclamationCircleOutlined),
content: 'Some descriptions',
okText: 'Yes',
okType: 'danger',
okButtonProps: {
disabled: true,
},
cancelText: 'No',
onOk() {
console.log('OK')
},
onCancel() {
console.log('Cancel')
},
})
}
return {
showConfirm,
showPromiseConfirm,
showDeleteConfirm,
showPropsConfirm
}
}
}
</script>信息提示
各种类型的信息提示,只提供一个按钮用于关闭。
<template>
<div>
<g-button @click="info">Info</g-button>
<g-button @click="success">Success</g-button>
<g-button @click="error">Error</g-button>
<g-button @click="warning">Warning</g-button>
</div>
</template>
<script>
import { Modal } from '@/components'
import { createVNode } from 'vue'
import {
ExclamationCircleOutlined,
CheckCircleOutlined,
CloseCircleOutlined,
InfoCircleOutlined
} from '@ant-design/icons-vue'
export default {
setup() {
const info = () => {
Modal.info({
title: 'This is a notification message',
icon: createVNode(InfoCircleOutlined),
content: 'some messages...some messages...',
onOk() {},
})
}
const success = () => {
Modal.success({
title: 'This is a success message',
icon: createVNode(CheckCircleOutlined),
content: 'some messages...some messages...',
})
}
const error = () => {
Modal.error({
title: 'This is an error message',
icon: createVNode(CloseCircleOutlined),
content: 'some messages...some messages...',
})
}
const warning = () => {
Modal.warning({
title: 'This is a warning message',
icon: createVNode(ExclamationCircleOutlined),
content: 'some messages...some messages...',
})
}
return {
info,
success,
error,
warning
}
}
}
</script>手动更新和移除
手动更新和关闭 Modal.method 方式创建的对话框。
<template>
<div>
<g-button @click="countDown">Open modal to close in 5s</g-button>
</div>
</template>
<script>
import { Modal } from '@/components'
export default {
setup() {
const countDown = () => {
let secondsToGo = 5
const modal = Modal.success({
title: 'This is a notification message',
content: `This modal will be destroyed after ${secondsToGo} second.`,
})
const timer = setInterval(() => {
secondsToGo -= 1
modal.update({
content: `This modal will be destroyed after ${secondsToGo} second.`,
})
}, 1000)
setTimeout(() => {
clearInterval(timer)
modal.destroy()
}, secondsToGo * 1000)
}
return {
countDown
}
}
}
</script>自定义位置
使用 centered 或类似 style.top 的样式来设置对话框位置。
<template>
<div>
<g-button type="primary" @click="setModal1Visible(true)">
Display a modal dialog at 20px to Top
</g-button>
<g-modal
title="20px to Top"
:style="{ top: '20px' }"
v-model:visible="modal1Visible"
@ok="() => setModal1Visible(false)"
>
<p>some contents...</p>
<p>some contents...</p>
<p>some contents...</p>
</g-modal>
<br /><br />
<g-button type="primary" @click="setModal2Visible(true)">
Vertically centered modal dialog
</g-button>
<g-modal
title="Vertically centered modal dialog"
centered
v-model:visible="modal2Visible"
@ok="() => setModal2Visible(false)"
>
<p>some contents...</p>
<p>some contents...</p>
<p>some contents...</p>
</g-modal>
</div>
</template>
<script>
import { ref } from 'vue'
export default {
setup() {
const modal1Visible = ref(false)
const modal2Visible = ref(false)
const setModal1Visible = (visible) => {
modal1Visible.value = visible
}
const setModal2Visible = (visible) => {
modal2Visible.value = visible
}
return {
modal1Visible,
modal2Visible,
setModal1Visible,
setModal2Visible
}
}
}
</script>自定义模态的宽度
使用 width 来设置模态对话框的宽度。
<template>
<div>
<g-button type="primary" @click="setModalVisible(true)">
Open Modal of 1000px width
</g-button>
<g-modal
title="Modal 1000px width"
centered
v-model:visible="modalVisible"
@ok="() => setModalVisible(false)"
width="1000px"
>
<p>some contents...</p>
<p>some contents...</p>
<p>some contents...</p>
</g-modal>
</div>
</template>
<script>
import { ref } from 'vue'
export default {
setup() {
const modalVisible = ref(false)
const setModalVisible = (visible) => {
modalVisible.value = visible
}
return {
modalVisible,
setModalVisible
}
}
}

const modal = Modal.info();
modal.update({
title: '修改的标题',
content: '修改的内容',
});
modal.destroy();Modal.destroyAll
使用 Modal.destroyAll() 可以销毁弹出的确认窗(即上述的 Modal.info、Modal.success、Modal.error、Modal.warning、Modal.confirm)。通常用于路由监听当中,处理路由前进、后退不能销毁确认对话框的问题,而不用各处去使用实例的返回值进行关闭(modal.destroy() 适用于主动关闭,而不是路由这样被动关闭)
import { watch } from 'vue';
import { Modal } from 'ant-design-vue';
watch(router.currentRoute, () => {
Modal.destroyAll();
});Modal.useModal()
当你需要使用 Context 时,可以通过 Modal.useModal 创建一个 contextHolder 插入子节点中。通过 hooks 创建的临时 Modal 将会得到 contextHolder 所在位置的所有上下文。创建的 modal 对象拥有与 [Modal.method] 相同的创建通知方法。
<template>
<div>
<contextHolder />
<!-- your components -->
</div>
</template>
<script>
import { Modal } from '@/components'
export default {
setup() {
const [modal, contextHolder] = Modal.useModal()
const info = () => {
modal.info({
title: 'Useful information',
content: 'some useful information',
})
}
return {
contextHolder,
info
}
}
}
</script>FAQ
为什么 Modal 方法不能获取 context、redux、的内容和 ConfigProvider locale/prefixCls/theme 等配置?
直接调用 Modal 方法,antdv 会通过 Vue.render 动态创建新的 Vue 实体。其 context 与当前代码所在 context 并不相同,因而无法获取 context 信息。
当你需要 context 信息(例如 ConfigProvider 配置)时,可以通过 Modal.useModal 方法会返回 api 实体以及 contextHolder 节点。将其插入到你需要获取 context 位置即可:
<template>
<div>
<contextHolder />
<!-- your components -->
</div>
</template>
<script>
import { Modal } from '@/components'
export default {
setup() {
const [api, contextHolder] = Modal.useModal()
const info = () => {
api.info({
// ...
})
}
return {
contextHolder,
info
}
}
}
</script>异同:通过 hooks 创建的 contextHolder 必须插入到子元素节点中才会生效,当你不需要上下文信息时请直接调用。
可通过 App 包裹组件 简化
useModal等方法需要手动植入 contextHolder 的问题。
