如何根据下标切换swiper-item，标题是根据下标进行切换的，但在swiper显示不了效果？ - WXOPEN Club

view wx:for="{{datalist}}" wx:key="" wx:for-item="item" style="">

<scroll-view scroll-x scroll-with-animation scroll-left="{{left}}" style="padding-left: 26vw;overflow-x: auto;height: 90rpx;white-space: nowrap; font-size: 9pt;">

<view wx:for="{{datalist}}" wx:key="" wx:for-item="item" style="display: inline-block;width:17vw;height:10vw;line-height:10vw;font-size:26rpx;text-align:center;text-align:center;" class="{{idIndex==index?'bottomBorder':''}}" bindtap="itemList" data-index="{{index}}">{{item}}</view>

</scroll-view>

<swiper current="{{currentTab}}" duration="300" bindchange="swiperTab" style="height: 93vh;">

<swiper-item>

<view wx:if="{{idIndex==index}}" bindtap="conIndex" data-index="{{index}}">
