+ * tabsSwiper 全屏选项卡
+ * @description 该组件内部实现主要依托于uniapp的scroll-view和swiper组件,主要特色是切换过程中,tabsSwiper文字的颜色可以渐变,底部滑块可以 跟随式滑动,活动tab滚动居中等。应用场景可以用于需要左右切换页面,比如商城的订单中心(待收货-待付款-待评价-已退货)等应用场景。
+ * @tutorial https://www.uviewui.com/components/tabsSwiper.html
+ * @property {Boolean} is-scroll tabs是否可以左右拖动(默认true)
+ * @property {Array} list 标签数组,元素为对象,如[{name: '推荐'}]
+ * @property {String Number} current 指定哪个tab为激活状态(默认0)
+ * @property {String Number} height 导航栏的高度,单位rpx(默认80)
+ * @property {String Number} font-size tab文字大小,单位rpx(默认30)
+ * @property {String Number} swiper-width tabs组件外部swiper的宽度,默认为屏幕宽度,单位rpx(默认750)
+ * @property {String} active-color 滑块和激活tab文字的颜色(默认#2979ff)
+ * @property {String} inactive-color tabs文字颜色(默认#303133)
+ * @property {String Number} bar-width 滑块宽度,单位rpx(默认40)
+ * @property {String Number} bar-height 滑块高度,单位rpx(默认6)
+ * @property {Object} bar-style 底部滑块的样式,对象形式
+ * @property {Object} active-item-style 活动tabs item的样式,对象形式
+ * @property {Boolean} show-bar 是否显示底部的滑块(默认true)
+ * @property {String Number} gutter 单个tab标签的左右内边距之和,单位rpx(默认40)
+ * @property {String} bg-color tabs导航栏的背景颜色(默认#ffffff)
+ * @property {String} name 组件内部读取的list参数中的属性名,见官网说明(默认name)
+ * @property {String} count 组件内部读取的list参数中的属性名(badge徽标数),同name属性的使用,见官网说明(默认count)
+ * @property {Array} offset 设置badge徽标数的位置偏移,格式为 [x, y],也即设置的为top和right的值,单位rpx(默认[5, 20])
+ * @property {Boolean} bold 激活选项的字体是否加粗(默认true)
+ * @event {Function} change 点击标签时触发
+ * @example <u-tabs-swiper ref="tabs" :list="list" :is-scroll="false"></u-tabs-swiper>
