15 * gridItem 提示
16 * @description 宫格组件一般用于同时展示多个同类项目的场景,可以给宫格的项目设置徽标组件(badge),或者图标等,也可以扩展为左右滑动的轮播形式。搭配u-grid使用
17 * @tutorial https://www.uviewui.com/components/grid.html
18 * @property {String} bg-color 宫格的背景颜色(默认#ffffff)
19 * @property {String Number} index 点击宫格时,返回的值
20 * @property {Object} custom-style 自定义样式,对象形式
21 * @event {Function} click 点击宫格触发
22 * @example <u-grid-item></u-grid-item>
