|      * @property {String} el-color 骨架块状元素的背景颜色(默认#e5e5e5) | 
|      * @property {String} bg-color 骨架组件背景颜色(默认#ffffff) | 
|      * @property {Boolean} animation 骨架块是否显示动画效果(默认false) | 
|      * @property {String Number} border-radius u-skeleton-fillet类名元素,对应的骨架块的圆角大小,单位rpx(默认10) | 
|      * @property {Boolean} loading 是否显示骨架组件,请求完成后,将此值设置为false(默认true) |
