| | | * grid 宫格布局 |
| | | * @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。 |
| | | * @tutorial https://www.uviewui.com/components/grid.html |
| | | * @property {String | Number} col 宫格的列数(默认 3 ) |
| | | * @property {Boolean} border 是否显示宫格的边框(默认 false ) |
| | | * @property {String} align 宫格对齐方式,表现为数量少的时候,靠左,居中,还是靠右 (默认 'left' ) |
| | | * @property {Object} customStyle 定义需要用到的外部样式 |
| | | * @event {Function} click 点击宫格触发 |
| | | * @example <u-grid :col="3" @click="click"></u-grid> |
