WXML

<view class="swiper-tab">
    <view class="swiper-tab-item {{currentTab==0?'active':''}}" data-current="0" bindtap="clickTab">一</view>
    <view class="swiper-tab-item {{currentTab==1?'active':''}}" data-current="1" bindtap="clickTab">二</view>
    <view class="swiper-tab-item {{currentTab==2?'active':''}}" data-current="2" bindtap="clickTab">三</view>
</view>

<swiper current="{{currentTab}}" duration="300"  bindchange="swiperTab">
    <swiper-item><view>这是第一屏内容</view></swiper-item>
    <swiper-item><view>这是第二屏内容</view></swiper-item>
    <swiper-item><view>这是第三屏内容</view></swiper-item>
</swiper>

JS

var app = getApp()
Page({
  data: {
    currentTab: 0
  },
  onLoad: function (options) {
    // 页面初始化 options为页面跳转所带来的参数
  },
  //滑动切换
  swiperTab: function (e) {
    var that = this;
    that.setData({
      currentTba: e.detail.current
    });
  },
  //点击切换
  clickTab: function (e) {
    var that = this;
    if (this.data.currentTab === e.target.dataset.current) {
      return false;
    } else {
      that.setData({
        currentTab: e.target.dataset.current
      })
    }
  }
})
