最近搞了个微信小程序切换的demo，有点像头条的那个，我给你大家分享下。
这里写图片描述
代码如下：
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>
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;}
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
})
}
}
})
这个可以在项目用，而且我之前也是见过有这样功能的小程序，特此献出代码，希望能帮到朋友们。
