# label
## Instructions
用来改进表单组件的可用性，使用for属性找到对应的id，或者将控件放在该标签下，当点击时，就会触发对应的控件。
for优先级高于内部控件，内部有多个控件的时候默认触发第一个控件。
目前可以绑定的控件有： <button> , <checkbox> , <radio> , <switch> 。
### Syntax
- 使用 `<label />`（或 `<label></label>`，当需要包裹子节点时）。
- 遇到平台差异时，建议使用条件编译（`#ifdef / #endif`）显式处理。
#### Properties
| 属性名 | 类型 | 说明 |
| --- | --- | --- |
| for | String | 绑定控件的 id |
#### Events
See official docs for full events list: `https://doc.dcloud.net.cn/uni-app-x/component/label.html`
#### Platform Compatibility
See official docs for platform support table: `https://doc.dcloud.net.cn/uni-app-x/component/label.html`
