Components | 包裹组件 | 1 | 其它 | App | https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*TBTSR4PyVmkAAAAAAAAAAAAADrJ8AQ/original | https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*JGb3RIzyOCkAAAAAAAAAAAAADrJ8AQ/original | New |
新的包裹组件,提供重置样式和提供消费上下文的默认环境。
何时使用
- 提供可消费 provide/inject 的
message.xxx
、Modal.xxx
、notification.xxx
的静态方法,可以简化 useMessage 等方法需要手动植入contextHolder
的问题。 - 提供基于
.ant-app
的默认重置样式,解决原生元素没有 antd 规范样式的问题。
API
App
参数 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
message | App 内 Message 的全局配置 | MessageConfig | - | 4.x |
notification | App 内 Notification 的全局配置 | NotificationConfig | - | 4.x |
如何使用
基础用法
App 组件通过 provide/inject
提供上下文方法调用,因而 useApp 需要作为子组件才能使用,我们推荐在应用中顶层包裹 App。
/*myPage.vue*/
<template>
<a-space>
<a-button type="primary" @click="showMessage">Open message</a-button>
<a-button type="primary" @click="showModal">Open modal</a-button>
<a-button type="primary" @click="showNotification">Open notification</a-button>
</a-space>
</template>
<script setup lang="ts">
import { App } from 'ant-design-vue';
const { message, modal, notification } = App.useApp();
const showMessage = () => {
message.success('Success!');
};
const showModal = () => {
modal.warning({
title: 'This is a warning message',
content: 'some messages...some messages...',
});
};
const showNotification = () => {
notification.info({
message: `Notification topLeft`,
description: 'Hello, Ant Design Vue!!',
placement: 'topLeft',
});
};
</script>
注意:App.useApp 必须在 App 之下方可使用。
内嵌使用场景(如无必要,尽量不做嵌套)
<a-app>
<a-space>
...
<a-app>...</a-app>
</a-space>
</a-app>
与 ConfigProvider 先后顺序
App 组件只能在 ConfigProvider
之下才能使用 Design Token, 如果需要使用其样式重置能力,则 ConfigProvider 与 App 组件必须成对出现。
<a-config-provider theme="{{ ... }}">
<a-app>...</a-app>
</a-config-provider>
全局场景 (pinia 场景)
import { App } from 'ant-design-vue';
import type { MessageInstance } from 'ant-design-vue/es/message/interface';
import type { ModalStaticFunctions } from 'ant-design-vue/es/modal/confirm';
import type { NotificationInstance } from 'ant-design-vue/es/notification/interface';
export const useGloablStore = defineStore('global', () => {
const message: MessageInstance = ref();
const notification: NotificationInstance = ref();
const modal: Omit<ModalStaticFunctions, 'warn'> = ref();
(() => {
const staticFunction = App.useApp();
message.value = staticFunction.message;
modal.value = staticFunction.modal;
notification.value = staticFunction.notification;
})();
return { message, notification, modal };
});
// sub page
<template>
<a-space>
<a-button type="primary" @click="showMessage">Open message</a-button>
</a-space>
</template>
<script setup>
import { useGlobalStore } from '@/stores/global';
const global = useGlobalStore();
const showMessage = () => {
global.message.success('Success!');
};
</script>
