微信小程序实现标签页滑块效果
小程序完整代码:
wxml:
<view class="swiper-tab">
<view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">留言</view>
<view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">活动</view>
<view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">更多</view>
</view>
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">
<swiper-item>
<view>
<image src='{{image}}' class='img'></image>
</view>
</swiper-item>
<swiper-item>
<view>
<image src='{{image}}' class='img'></image>
</view>
</swiper-item>
<swiper-item>
<view>
<image src='{{image}}' class='img'></image>
</view>
</swiper-item>
</swiper>
wxss:
