WXML中：

<view class="swiper-tab">
　　<view class="swiper-tab-list {{currentTab==0 ? ‘on‘ : ‘‘}}" data-current="0" bindtap="swichNav">地图</view>
　　<view class="swiper-tab-list {{currentTab==1 ? ‘on‘ : ‘‘}}" data-current="1" bindtap="swichNav">列表</view>
</view>
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">
　　<!-- 地图 -->
　　<swiper-item>
　　　　<view>地图</view>
　　</swiper-item>
<!-- 列表 -->
　　<swiper-item>
　　　　<view>列表</view>
　　</swiper-item>
</swiper>

js中：

var app = getApp()
Page({
  data: {
    winWidth: 0,
    winHeight: 0,
    // tab切换  
    currentTab: 0,
  },
  onLoad: function () {
    var that = this;
    /** 
     * 获取系统信息 
     */
    wx.getSystemInfo({
      success: function (res) {
        that.setData({
          winWidth: res.windowWidth,
          winHeight: res.windowHeight
        });
      }
    });
  },
  /** 
     * 滑动切换tab 
     */
  bindChange: function (e) {
    var that = this;
    that.setData({ currentTab: e.detail.current });
  },
  /** 
   * 点击tab切换 
   */
  swichNav: function (e) {
    var that = this;
    if (this.data.currentTab === e.target.dataset.current) {
      return false;
    } else {
      that.setData({
        currentTab: e.target.dataset.current
      })
    }
  }
})
