- * switch 开关选择器
- * @description 选择开关一般用于只有两个选择,且只能选其一的场景。
- * @tutorial https://www.uviewui.com/components/switch.html
- * @property {Boolean} loading 是否处于加载中(默认false)
- * @property {Boolean} disabled 是否禁用(默认false)
- * @property {String Number} size 开关尺寸,单位rpx(默认50)
- * @property {String} active-color 打开时的背景色(默认#2979ff)
- * @property {Boolean} inactive-color 关闭时的背景色(默认#ffffff)
- * @property {Boolean | Number | String} active-value 打开选择器时通过change事件发出的值(默认true)
- * @property {Boolean | Number | String} inactive-value 关闭选择器时通过change事件发出的值(默认false)
- * @event {Function} change 在switch打开或关闭时触发
- * @example <u-switch v-model="checked" active-color="red" inactive-color="#eee"></u-switch>
