vue2版本
uniapp组件之tab选项卡滑动切换
效果如下：
代码如下：
<template>
<view class="content">
<view class="nav">
<!-- 选项卡水平方向滑动，scroll-with-animation是滑动到下一个选项时，有一个延时效果 -->
<scroll-view class="tab-scroll" scroll-x="true" scroll-with-animation :scroll-left="scrollLeft">
<view class="tab-scroll_box">
<!-- 选项卡类别列表 -->
<view class="tab-scroll_item" v-for=" (item,index) in category" :key="index" :class="{'active':isActive==index}" @click="chenked(index)">
{{item.name}}
</view>
</view>
</scroll-view>
</view>
<!-- 选项卡内容轮播滑动显示，current为当前第几个swiper子项 -->
<swiper @change="change" :current="isActive" class="swiper-content" :style="fullHeight">
<swiper-item class="swiperitem-content">
<scroll-view scroll-y style="height: 100%;">
<view class="nav_item" >
选项卡1页面
</view>
</scroll-view>
</swiper-item>
<swiper-item class="swiperitem-content">

注意：css当中需要加上以下，为了隐藏滚动条，否则会出现下图效果
/* 隐藏滚动条，但依旧具备可以滚动的功能 */
/deep/.uni-scroll-view::-webkit-scrollbar {
display: none
}
