小程序选项卡小Demo，可滑动控制

思绪
1.选项卡使用scroll-view,实现可以滑动控制效果；
2.使用current控制选项卡标题和内容的统一，实现同步操作；
3.winHeight 这个是我最常用的var calc = clientHeight * rpxR - 440; 440这个值是你所不需要计算的高度值，取决于你除内容之外的高度；
wxml文件

<view class="pinConDet">
  <view class='title'>标题</view>
  <view class='con'>
    <scroll-view scroll-x="true" class="tab-h" scroll-left="{{scrollLeft}}" class='tabBox'>
        <view class="tab-item {{currentTab==0?'active':''}}"  data-current="0" bindtap="swichNav">选项1</view>
        <view class="tab-item {{currentTab==1?'active':''}}" data-current="1" bindtap="swichNav">选项2</view>    
    </scroll-view>
    <swiper class="tab-content" current="{{currentTab}}" duration="300" bindchange="switchTab"
     style="height:{{winHeight}}rpx">
      <swiper-item>
        <scroll-view scroll-y="true" class="scoll-h" >
          <view class="title1">
            选项卡1内容
          </view>
        </scroll-view>
      </swiper-item>
      <swiper-item>
        <scroll-view scroll-y="true" class="scoll-h" >
          <view class="title1">
            选项卡2内容
          </view>
        </scroll-view>
      </swiper-item>
    </swiper>
  </view>
</view>

js文件

var app = getApp()
Page({
  data: {
    winHeight: "",//窗口高度
    currentTab: 0, //预设当前项的值
    scrollLeft: 0, //tab标题的滚动条位置
    showView: false,
    cWayshow: false,
  },
  // 滚动切换标签样式
  switchTab: function (e) {
    this.setData({
      currentTab: e.detail.current
      //获取当前事件current的值；
    });
    this.checkCor();
  },
  // 点击标题切换当前页时改变样式
  swichNav: function (e) {
    var cur = e.target.dataset.current;
    if (this.data.currentTaB == cur) { return false; }
    else {
      this.setData({
        currentTab: cur
      })
    }
  },
  //判断当前滚动超过一屏时，设置tab标题滚动条。
  checkCor: function () {
    if (this.data.currentTab > 4) {
      this.setData({
        scrollLeft: 300
      })
    } else {
      this.setData({
        scrollLeft: 0
      })
    }
  },
  onLoad: function (options) {
    showView: (options.showView == "true" ? true : false);
    cWayshow: (options.showView == "true" ? true : false);
    var that = this;
    //  高度自适应
    wx.getSystemInfo({
      success: function (res) {
        var clientHeight = res.windowHeight,
          clientWidth = res.windowWidth,
          rpxR = 750 / clientWidth;
        console.log(clientHeight)
        var calc = clientHeight * rpxR - 440;
        console.log(calc)
        that.setData({
          winHeight: calc
        });
      }
    });
  }
})

最后实现效果样式呈现
