一、功能描述
在同一个页面内实现不同展示页面的切换功能，如下图所示

二、代码实现

1. index.js

Page({

    /**
     * 页面的初始数据
     */
    data: {
        currentData: 0,
    },
    /**
     * 生命周期函数--监听页面加载
     */
    onLoad: function (options) {
    },
    //获取当前滑块的index
    bindchange: function (e) {
        const that = this;
        that.setData({
            currentData: e.detail.current
        })
    },
    //点击切换，滑块index赋值
    checkCurrent: function (e) {
        const that = this;

        if (that.data.currentData === e.target.dataset.current) {
            return false;
        } else {

            that.setData({
                currentData: e.target.dataset.current
            })
        }
    }
})

2. index.wxml

<view class='topTabSwiper'>
    <view class='tab  {{currentData == 0 ? "tabBorer" : ""}}'  data-current = "0" bindtap='checkCurrent'>推荐</view>
    <view class='tab  {{currentData == 1 ? "tabBorer" : ""}}'  data-current = "1" bindtap='checkCurrent'>热点</view>
    <view class='tab  {{currentData == 2 ? "tabBorer" : ""}}'  data-current = "2" bindtap='checkCurrent'>关注</view>
</view>
<swiper current="{{currentData}}" class='swiper' style="height:600px;" duration="300" bindchange="bindchange">
    <swiper-item><view class='swiper_con'>welcome come to 推荐</view></swiper-item>
    <swiper-item><view class='swiper_con'>welcome come to 热点</view></swiper-item>
    <swiper-item><view class='swiper_con'>welcome come to 关注</view></swiper-item> 
</swiper>

3. index.wxss

.tab {
float: left;
width: 33.3333%;
text-align: center;
padding: 10rpx 0;
}

.topTabSwiper {
border-top: 1px solid #ccc;
border-bottom: 1px solid #ccc;
zoom: 1;
}

.topTabSwiper:after {
content: "";
clear: both;
display: block;
}

.tabBorer {
border-bottom: 1px solid #f00;
color: #f00;
}

.swiper {
width: 100%;
}

.swiper_con {
text-align: center;
width: 100%;
height: 100%;
padding: 80rpx 0;
}
