* badge 角标
|

* @description 本组件一般用于展示头像的地方,如个人中心,或者评论列表页的用户头像展示等场所。
|
||
* @tutorial https://uviewpro.cn/zh/components/badge.html
|
||
* @property {String|Number} count 展示的数字,大于 overflowCount 时显示为 ${overflowCount}+,为0且show-zero为false时隐藏
|
||
* @property {Boolean} is-dot 不展示数字,只有一个小点(默认false)
|
||
* @property {Boolean} absolute 组件是否绝对定位,为true时,offset参数才有效(默认true)
|
||
* @property {String|Number} overflow-count 展示封顶的数字值(默认99)
|
||
* @property {String} type 使用预设的背景颜色(默认error)
|
||
* @property {Boolean} show-zero 当数值为 0 时,是否展示 Badge(默认false)
|
||
* @property {String} size Badge的尺寸,设为mini会得到小一号的Badge(默认default)
|
||
* @property {Array} offset 设置badge的位置偏移,格式为 [x, y],也即设置的为top和right的值,单位rpx。absolute为true时有效(默认[20, 20])
|
||
* @property {String} color 字体颜色(默认var(--u-white-color))
|
||
* @property {String} bgColor 背景颜色,优先级比type高,如设置,type参数会失效
|
||
* @property {Boolean} is-center 组件中心点是否和父组件右上角重合,优先级比offset高,如设置,offset参数会失效(默认false)
|
||
* @example <u-badge type="error" count="7"></u-badge>
