| | | * checkbox 复选框 |
| | | * @description 复选框组件一般用于需要多个选择的场景,该组件功能完整,使用方便 |
| | | * @tutorial https://uviewui.com/components/checkbox.html |
| | | * @property {String | Number | Boolean} name checkbox组件的标示符 |
| | | * @property {String} shape 形状,square为方形,circle为圆型 |
| | | * @property {String | Number} size 整体的大小 |
| | | * @property {Boolean} checked 是否默认选中 |
| | | * @property {String | Boolean} disabled 是否禁用 |
| | | * @property {String} activeColor 选中状态下的颜色,如设置此值,将会覆盖parent的activeColor值 |
| | | * @property {String} inactiveColor 未选中的颜色 |
| | | * @property {String | Number} iconSize 图标的大小,单位px |
| | | * @property {String} iconColor 图标颜色 |
| | | * @property {String | Number} label label提示文字,因为nvue下,直接slot进来的文字,由于特殊的结构,无法修改样式 |
| | | * @property {String} labelColor label的颜色 |
| | | * @property {String | Number} labelSize label的字体大小,px单位 |
| | | * @property {String | Boolean} labelDisabled 是否禁止点击提示语选中复选框 |
| | | * @property {Object} customStyle 定义需要用到的外部样式 |
| | | * |
| | | * @event {Function} change 任一个checkbox状态发生变化时触发,回调为一个对象 |
| | | * @example <u-checkbox v-model="checked" :disabled="false">天涯</u-checkbox> |
