|
|||
|
|
|
|||
|
|
### 介绍
|
|||
|
|
|
|||
|
|
底部弹起的分享面板，用于展示各分享渠道对应的操作按钮，不含具体的分享逻辑。
|
|||
|
|
|
|||
|
|
### 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 { ShareSheet } from 'vant';
|
|||
|
|
|
|||
|
|
const app = createApp();
|
|||
|
|
app.use(ShareSheet);

|
|
```
|
|||
|
|
|
|||
|
|
## 代码演示
|
|||
|
|
|
|||
|
|
### 基础用法
|
|||
|
|
|
|||
|
|
分享面板通过 `options` 属性来定义分享选项，数组的每一项是一个对象，对象格式见文档下方表格。
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<van-cell title="显示分享面板" @click="showShare = true" />
|
|||
|
|
<van-share-sheet
|
|||
|
|
v-model:show="showShare"
|
|||
|
|
title="立即分享给好友"
|
|||
|
|
:options="options"
|
|||
|
|
@select="onSelect"
|
|||
|
|
/>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
import { ref } from 'vue';
|
|||
|
|
import { showToast } from 'vant';
|
|||
|
|
|
|||
|
|
export default {
|
|||
|
|
setup() {
|
|||
|
|
const showShare = ref(false);
|
|||
|
|
const options = [
|
|||
|
|
{ name: '微信', icon: 'wechat' },
|
|||
|
|
{ name: '微博', icon: 'weibo' },
|
|||
|
|
{ name: '复制链接', icon: 'link' },
|
|||
|
|
{ name: '分享海报', icon: 'poster' },
|
|||
|
|
{ name: '二维码', icon: 'qrcode' },
|
|||
|
|
];
|
|||
|
|
|
|||
|
|
const onSelect = (option) => {
|
|||
|
|
showToast(option.name);
|
|||
|
|
showShare.value = false;
|
|||
|
|
};
|
|||
|
|
|
|||
|
|
return {
|
|||
|
|
options,
|
|||
|
|
onSelect,
|
|||
|
|
showShare,
|
|||
|
|
};
|
|||
|
|
},
|
|||
|
|
};
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 展示多行选项
|
|||
|
|
|
|||
|
|
当分享选项的数量较多时，可以将 `options` 定义为数组嵌套的格式，每个子数组会作为一行选项展示。
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<van-share-sheet
|
|||
|
|
v-model:show="showShare"
|
|||
|
|
title="立即分享给好友"
|
|||
|
|
:options="options"
|
|||
|
|
/>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
import { ref } from 'vue';
|
|||
|
|
|
|||
|
|
export default {
|
|||
|
|
setup() {
|
|||
|
|
const showShare = ref(false);
|
|||
|
|
const options = [
|
|||
|
|
[
|
|||
|
|
{ name: '微信', icon: 'wechat' },
|
|||
|
|
{ name: '朋友圈', icon: 'wechat-moments' },
|
|||
|
|
{ name: '微博', icon: 'weibo' },
|
|||
|
|
{ name: 'QQ', icon: 'qq' },
|
|||
|
|
],
|
|||
|
|
[
|
|||
|
|
{ name: '复制链接', icon: 'link' },
|
|||
|
|
{ name: '分享海报', icon: 'poster' },
|
|||
|
|
{ name: '二维码', icon: 'qrcode' },
|
|||
|
|
{ name: '小程序码', icon: 'weapp-qrcode' },
|
|||
|
|
],
|
|||
|
|
];
|
|||
|
|
|
|||
|
|
return {
|
|||
|
|
options,
|
|||
|
|
showShare,
|
|||
|
|
};
|
|||
|
|
},
|
|||
|
|
};
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 自定义图标
|
|||
|
|
|
|||
|
|
除了使用内置的几种图标外，可以直接在 `icon` 中传入图片 URL 来使用自定义的图标。
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<van-share-sheet v-model:show="showShare" :options="options" />
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
import { ref } from 'vue';
|
|||
|
|
|
|||
|
|
export default {
|
|||
|
|
setup() {
|
|||
|
|
const showShare = ref(false);
|
|||
|
|
const options = [
|
|||
|
|
{
|
|||
|
|
name: '名称',
|
|||
|
|
icon: 'https://fastly.jsdelivr.net/npm/@vant/assets/custom-icon-fire.png',
|
|||
|
|
},
|
|||
|
|
{
|
|||
|
|
name: '名称',
|
|||
|
|
icon: 'https://fastly.jsdelivr.net/npm/@vant/assets/custom-icon-light.png',
|
|||
|
|
},
|
|||
|
|
{
|
|||
|
|
name: '名称',
|
|||
|
|
icon: 'https://fastly.jsdelivr.net/npm/@vant/assets/custom-icon-water.png',
|
|||
|
|
},
|
|||
|
|
];
|
|||
|
|
|
|||
|
|
return {
|
|||
|
|
options,
|
|||
|
|
showShare,
|
|||
|
|
};
|
|||
|
|
},
|
|||
|
|
};
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 展示描述信息
|
|||
|
|
|
|||
|
|
通过 `description` 属性可以设置标题下方的描述文字, 在 `options` 内设置 `description` 属性可以添加分享选项描述。
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<van-share-sheet
|
|||
|
|
v-model:show="showShare"
|
|||
|
|
:options="options"
|
|||
|
|
title="立即分享给好友"
|
|||
|
|
description="描述信息"
|
|||
|
|
/>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
import { ref } from 'vue';
|
|||
|
|
|
|||
|
|
export default {
|
|||
|
|
setup() {
|
|||
|
|
const showShare = ref(false);
|
|||
|
|
const options = [
|
|||
|
|
{ name: '微信', icon: 'wechat' },
|
|||
|
|
{ name: '微博', icon: 'weibo' },
|
|||
|
|
{ name: '复制链接', icon: 'link', description: '描述信息' },
|
|||
|
|
{ name: '分享海报', icon: 'poster' },
|
|||
|
|
{ name: '二维码', icon: 'qrcode' },
|
|||
|
|
];
|
|||
|
|
|
|||
|
|
return {
|
|||
|
|
options,
|
|||
|
|
showShare,
|
|||
|
|
};
|
|||
|
|
},
|
|||
|
|
};
|
|||
|
|
```
|
|||

## 常见问题
|
|||
|
|
|
|||
|
|
### 如何实现分享逻辑？
|
|||
|
|
|
|||
|
|
在不同的 App 或浏览器中，存在各式各样的分享接口或分享方式，因此 ShareSheet 组件不提供具体的分享逻辑，需要开发者根据业务场景自行实现。
|
|||
|
|
|
|||
|
|
#### 微信内分享
|
|||
|
|
|
|||
|
|
由于微信未提供分享相关的 API，需要引导用户点击右上角进行分享。
|
|||
|
|
|
|||
|
|
#### App 内分享
|
|||
|
|
|
|||
|
|
可以通过 JSBridge 调用原生应用的 SDK 进行分享。
|
|||
|
|
|
|||
|
|
#### 分享海报或二维码
|
|||
|
|
|
|||
|
|
可以通过 [Popup](#/zh-CN/popup) 组件以弹层的形式展示图片，然后引导用户保存图片进行分享。
|
