一：窗口顶部TabBar页面切换
微信小程序开发中选项卡.在Android中选项卡一般用fragment,到了小程序这里瞬间懵逼了.
总算做出来了.分享出来看看。
先看效果：
再上代码:
1.index.wxml
<!--index.wxml-->
<view class="swiper-tab">
<view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">哈哈</view>
<view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">呵呵</view>
<view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">嘿嘿</view>
</view>
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">
<!-- 我是哈哈 -->
<swiper-item>
<view>我是哈哈</view>
</swiper-item>
<!-- 我是呵呵 -->
<swiper-item>
<view>我是呵呵</view>
</swiper-item>
<!-- 我是嘿嘿 -->
<swiper-item>
<view>我是嘿嘿</view>
</swiper-item>
</swiper>

2.index.wxss
/**index.wxss**/
.swiper-tab{
width: 100%;
border-bottom: 2rpx solid #777777;
