先看效果图：

这个滑块除了可以点击上方的导航，还可以左右切换页面，随之导航也跟这切换。

实现步骤：

编写滑块视图代码
编写逻辑代码

wxml:

<view class="content">
  <view class="title">
    <view class="{{currentTab==0" data-current="0" bindtap="switchNav">关注</view>
    <view class="{{currentTab==1" data-current="1" bindtap="switchNav">新鲜</view>
    <view class="{{currentTab==2" data-current="2" bindtap="switchNav">推荐</view>
  </view>
  <swiper class="swiper" bindchange="swiperchange" current="{{currentTab}}" style="height:{{winHeight}}px">
    <swiper-item item-id="{{item.id}}">
      关注
    </swiper-item>
    <swiper-item item-id="{{item.id}}">
      新鲜
    </swiper-item>
    <swiper-item item-id="{{item.id}}">
      推荐
    </swiper-item>
  </swiper>
</view>

wxss:

.title{
  display: flex;
  flex-direction: row;
  width: 100%;
  background-color: #ff99cc;
  height: 100rpx;
  position: fixed;
  z-index: 9999999999999;
}
.select{
  width: 33%;
  text-align: center;
  height: 45px;
  line-height: 45px;
  color: white;
  border-bottom: 5rpx solid #ff99cc;
}
.default{
  margin:0 auto;
  padding:15px;
  color: #666;
}
.swiper{
  margin-top: 100rpx;
}

js:

data: {
  currentTab:1,
  winWidth:0,
  winHeight:0
 },

onLoad: function (options) {
  wx.getSystemInfo({
   complete: (res) => {
    this.setData({
     winWidth:res.windowWidth,
     winHeight:res.windowHeight
    })
   },
  })
 },
 switchNav(e){
  console.log(e)
  if(this.data.currentTab==e.target.dataset.current){
   return false
  }else{
   this.setData({
    currentTab:e.target.dataset.current
   })
  }
 },
 swiperchange(e){
  this.setData({
   currentTab:e.detail.current
  })
 },
