- {String} src 头像路径,如加载失败,将会显示默认头像(不能为相对路径)
- * @property {String} shape 头像形状 ( circle (默认) | square)
- * @property {String | Number} size 头像尺寸,可以为指定字符串(large, default, mini),或者数值 (默认 40 )
- * @property {String} mode 头像图片的裁剪类型,与uni的image组件的mode参数一致,如效果达不到需求,可尝试传widthFix值 (默认 'scaleToFill' )
- * @property {String} text 用文字替代图片,级别优先于src
- * @property {String} bgColor 背景颜色,一般显示文字时用 (默认 '#c0c4cc' )
- * @property {String} color 文字颜色 (默认 '#ffffff' )
- * @property {String | Number} fontSize 文字大小 (默认 18 )
- * @property {String} icon 显示的图标
- * @property {Boolean} mpAvatar 显示小程序头像,只对百度,微信,QQ小程序有效 (默认 false )
- * @property {Boolean} randomBgColor 是否使用随机背景色 (默认 false )
- * @property {String} defaultUrl 加载失败的默认头像(组件有内置默认图片)
- * @property {String | Number} colorIndex 如果配置了randomBgColor为true,且配置了此值,则从默认的背景色数组中取出对应索引的颜色值,取值0-19之间
- * @property {String} name 组件标识符 (默认 'level' )
- * @property {Object} customStyle 定义需要用到的外部样式
- *
- * @event {Function} click 点击组件时触发 index: 用户传递的标识符
- * @example <u-avatar :src="src" mode="square"></u-avatar>
