# Popover 气泡弹出框
|
||
|
||
### 介绍
|
||
|
||
弹出式的气泡菜单。
|
||
|
||
### 引入
|
||
|
||
通过以下方式来全局注册组件,更多注册方式请参考[组件注册](#/zh-CN/advanced-usage#zu-jian-zhu-ce)。
|
||
|
||
```js
|
||
import { createApp } from 'vue';
|
||
import { Popover } from 'vant';
|
||
|
||
const app = createApp();
|
||
app.use(Popover);
|
||
```
|
||
|
||
## 代码演示
|
||
|
||
### 基础用法
|
||
|
||
当 Popover 弹出时,会基于 `reference` 插槽的内容进行定位。
|
||
|
||
```html
|
||
<van-popover v-model:show="showPopover" :actions="actions" @select="onSelect">
|
||
<template #reference>
|
||
<van-button type="primary">浅色风格</van-button>
|
||
</template>
|
||
</van-popover>
|
||
```
|
||
|
||
```js
|
||
import { ref } from 'vue';
|
||
import { showToast } from 'vant';
|
||
|
||
export default {
|
||
setup() {
|
||
const showPopover = ref(false);
|
||
|
||
// 通过 actions 属性来定义菜单选项
|
||
const actions = [
|
||
{ text: '选项一' },
|
||
{ text: '选项二' },
|
||
{ text: '选项三' },
|
||
];
|
||
const onSelect = (action) => showToast(action.text);
|
||
|
||
return {
|
||
actions,
|
||
onSelect,
|
||
showPopover,
|
||
};
|
||
},
|
||
};
|
||
```
|
||
|
||
### 深色风格
|
||
|
||
Popover 支持浅色和深色两种风格,默认为浅色风格,将 `theme` 属性设置为 `dark` 可切换为深色风格。
|
||
|
||
```html
|
||
<van-popover v-model:show="showPopover" theme="dark" :actions="actions">
|
||
<template #reference>
|
||
<van-button type="primary">深色风格</van-button>
|
||
</template>
|
||
</van-popover>
|
||
```
|
||
|
||
```js
|
||
import { ref } from 'vue';
|
||
|
||
export default {
|
||
setup() {
|
||
const showPopover = ref(false);
|
||
const actions = [
|
||
{ text: '选项一' },
|
||
{ text: '选项二' },
|
||
{ text: '选项三' },
|
||
];
|
||
|
||
return {
|
||
actions,
|
||
showPopover,
|
||
};
|
||
},
|
||
};
|
||
```
|
||
|
||
### 水平排列
|
||
|
||
将 `actions-direction` 属性设置为 `horizontal` 后,菜单选项会变成水平排列。
|
||
|
||
```html
|
||
<van-popover
|
||
v-model:show="showPopover"
|
||
:actions="actions"
|
||
actions-direction="horizontal"
|
||
>
|
||
<template #reference>
|
||
<van-button type="primary">水平排列</van-button>
|
||
</template>
|
||
</van-popover>
|
||
```
|
||
|
||
```js
|
||
import { ref } from 'vue';
|
||
|
||
export default {
|
||
setup() {
|
||
const showPopover = ref(false);
|
||
const actions = [
|
||
{ text: '选项一' },
|
||
{ text: '选项二' },
|
||
{ text: '选项三' },
|
||
];
|
||
|
||
return {
|
||
actions,
|
||
showPopover,
|
||
};
|
||
},
|
||
};
|
||
```
|
||
|
||
### 弹出位置
|
||
|
||
通过 `placement` 属性来控制气泡的弹出位置。
|
||
|
||
```html
|
||
<van-popover placement="top" />
|
||
```
|
||
|
||
`placement` 支持以下值:
|
||
|
||
```bash
|
||
top # 顶部中间位置
|
||
top-start # 顶部左侧位置
|
||
top-end # 顶部右侧位置
|
||
left # 左侧中间位置
|
||
left-start # 左侧上方位置
|
||
left-end # 左侧下方位置
|
||
right # 右侧中间位置
|
||
right-start # 右侧上方位置
|
||
right-end # 右侧下方位置
|
||
bottom # 底部中间位置
|
||
bottom-start # 底部左侧位置
|
||
bottom-end # 底部右侧位置
|
||
```
|
||
|
||
### 展示图标
|
||
|
||
在 `actions` 数组中,可以通过 `icon` 字段来定义选项的图标,支持传入图标名称或图片链接,等同于 Icon 组件的 [name 属性](#/zh-CN/icon#props)。
|
||
|
||
```html
|
||
<van-popover v-model:show="showPopover" :actions="actions">
|
||
<template #reference>
|
||
<van-button type="primary">展示图标</van-button>
|
||
</template>
|
||
</van-popover>
|
||
```
|
||
|
||
```js
|
||
import { ref } from 'vue';
|
||
|
||
export default {
|
||
setup() {
|
||
const showPopover = ref(false);
|
||
const actions = [
|
||
{ text: '选项一', icon: 'add-o' },
|
||
{ text: '选项二', icon: 'music-o' },
|
||
{ text: '选项三', icon: 'more-o' },
|
||
];
|
||
|
||
return {
|
||
actions,
|
||
showPopover,
|
||
};
|
||
},
|
||
};
|
||
```
|
||
|
||
### 禁用选项
|
||
|
||
在 `actions` 数组中,可以通过 `disabled` 字段来禁用某个选项。
|
||
|
||
```html
|
||
<van-popover v-model:show="showPopover" :actions="actions">
|
||
<template #reference>
|
||
<van-button type="primary">禁用选项</van-button>
|
||
</template>
|
||
</van-popover>
|
||
```
|
||
|
||
```js
|
||
import { ref } from 'vue';
|
||
|
||
export default {
|
||
setup() {
|
||
const showPopover = ref(false);
|
||
const actions = [
|
||
{ text: '选项一', disabled: true },
|
||
{ text: '选项二', disabled: true },
|
||
{ text: '选项三' },
|
||
];
|
||
|
||
return {
|
||
actions,
|
||
showPopover,
|
||
};
|
||
},
|
||
};
|
||
```
|
||
|
||
### 自定义内容
|
||
|
||
通过默认插槽,可以在 Popover 内部放置任意内容。
|
||
|
||
```html
|
||
<van-popover v-model:show="showPopover">
|
||
<van-grid
|
||
square
|
||
clickable
|
||
:border="false"
|
||
column-num="3"
|
||
style="width: 240px;"
|
||
>
|
||
<van-grid-item
|
||
v-for="i in 6"
|
||
:key="i"
|
||
text="选项"
|
||
icon="photo-o"
|
||
@click="showPopover = false"
|
||
/>
|
||
</van-grid>
|
||
<template #reference>
|
||
<van-button type="primary">自定义内容</van-button>
|
||
</template>
|
||
</van-popover>
|
||
```
|
||
|
||
```js
|
||
import { ref } from 'vue';
|
||
|
||
export default {
|
||
setup() {
|
||
const showPopover = ref(false);
|
||
return { showPopover };
|
||
},
|
||
};
|
||
```
|
||
|
||
### 非受控模式
|
||
|
||
你可以把 Popover 当做受控组件或非受控组件使用:
|
||
|
||
- 当绑定 `v-model:show` 时,Popover 为受控组件,此时组件的显示完全由 `v-model:show` 的值决定。
|
||
- 当未绑定 `v-model:show` 时,Popover 为非受控组件,此时你可以通过 `show` 属性传入一个默认值,组件值的显示由组件自身控制。
|
||
|
||
```html
|
||
<van-popover :actions="actions" placement="top-start" @select="onSelect">
|
||
<template #reference>
|
||
<van-button type="primary">非受控模式</van-button>
|
||
</template>
|
||
</van-popover>
|
||
```
|
||
|
||
```js
|
||
import { ref } from 'vue';
|
||
import { showToast } from 'vant';
|
||
|
||
export default {
|
||
setup() {
|
||
const actions = [
|
||
{ text: '选项一' },
|
||
{ text: '选项二' },
|
||
{ text: '选项三' },
|
||
];
|
||
const onSelect = (action) => showToast(action.text);
|
||
return {
|
||
actions,
|
||
onSelect,
|
||
};
|
||
},
|
||
};
|
||
```

## 常见问题
|
||
|
||
### Popover 的点击事件无法正确触发?
|
||
|
||
这种情况通常是由于项目中引入了 `fastclick` 库导致的。建议移除 `fastclick`,或者配置 `fastclick` 的 [ignore 规则](https://github.com/ftlabs/fastclick#advanced)。
