## Collapse 折叠面板
|
||||
|
||||
### 使用指南
|
||||
在 app.json 或 index.json 中引入组件
|
||||
```json
|
||||
"usingComponents": {
|
||||
"van-collapse": "path/to/vant-weapp/dist/collapse/index",
|
||||
"van-collapse-item": "path/to/vant-weapp/dist/collapse-item/index"
|
||||
}
|
||||
```
|
||||
|
||||
### 代码演示
|
||||
|
||||
#### 基础用法
|
||||
通过`value`控制展开的面板列表，`activeNames`为数组格式
|
||||
|
||||
```html
|
||||
<van-collapse value="{{ activeNames }}">
|
||||
<van-collapse-item title="有赞微商城" name="1">
|
||||
提供多样店铺模板，快速搭建网上商城
|
||||
</van-collapse-item>
|
||||
<van-collapse-item title="有赞零售" name="2">
|
||||
网店吸粉获客、会员分层营销、一机多种收款，告别经营低效和客户流失
|
||||
</van-collapse-item>
|
||||
<van-collapse-item title="有赞美业" name="3" disabled>
|
||||
线上拓客，随时预约，贴心顺手的开单收银
|
||||
</van-collapse-item>
|
||||
</van-collapse>
|
||||
```
|
||||
|
||||
``` javascript
|
||||
Page({
|
||||
data: {
|
||||
activeNames: ['1']
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
#### 手风琴
|
||||
通过`accordion`可以设置为手风琴模式，最多展开一个面板，此时`activeName`为字符串格式
|
||||
|
||||
```html
|
||||
<van-collapse value="{{ activeName }}" accordion>
|
||||
<van-collapse-item title="有赞微商城" name="1">
|
||||
提供多样店铺模板，快速搭建网上商城
|
||||
</van-collapse-item>
|
||||
<van-collapse-item title="有赞零售" name="2">
|
||||
网店吸粉获客、会员分层营销、一机多种收款，告别经营低效和客户流失
|
||||
</van-collapse-item>
|
||||
<van-collapse-item title="有赞美业" name="3">
|
||||
线上拓客，随时预约，贴心顺手的开单收银
|
||||
</van-collapse-item>
|
||||
</van-collapse>
|
||||
```
|
||||
|
||||
``` javascript
|
||||
Page({
|
||||
data: {
|
||||
activeName: '1'
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
#### 自定义标题内容
|
||||
|
||||
```html
|
||||
<van-collapse value="{{ activeNames }}">
|
||||
<van-collapse-item name="1">
|
||||
<view slot="title">有赞微商城<van-icon name="question" /></view>
|
||||
提供多样店铺模板，快速搭建网上商城
|
||||
</van-collapse-item>
|
||||
<van-collapse-item title="有赞零售" name="2">
|
||||
网店吸粉获客、会员分层营销、一机多种收款，告别经营低效和客户流失
|
||||
</van-collapse-item>
|
||||
</van-collapse>
|
||||
```

||||
|
||||
|
||||
|
||||
