+ * sticky 吸顶
+ * @description 该组件与CSS中position: sticky属性实现的效果一致，当组件达到预设的到顶部距离时， 就会固定在指定位置，组件位置大于预设的顶部距离时，会重新按照正常的布局排列。
+ * @tutorial https://www.uviewui.com/components/sticky.html
+ * @property {String Number} offset-top 吸顶时与顶部的距离，单位rpx（默认0）
+ * @property {String Number} index 自定义标识，用于区分是哪一个组件
+ * @property {Boolean} enable 是否开启吸顶功能（默认true）
+ * @property {String} bg-color 组件背景颜色（默认#ffffff）
+ * @property {String Number} z-index 吸顶时的z-index值（默认970）
+ * @property {String Number} h5-nav-height 导航栏高度，自定义导航栏时(无导航栏时需设置为0)，需要传入此值，单位px（默认44）
+ * @event {Function} fixed 组件吸顶时触发
+ * @event {Function} unfixed 组件取消吸顶时触发
+ * @example <u-sticky offset-top="200"><view>塞下秋来风景异，衡阳雁去无留意</view></u-sticky>
