微信小程序里没有自带选项卡组件，但是却带有swiper组件，所以，我们便利用swiper来实现选项卡的功能。
先看效果图：
test.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 class='swi' current="{{currentTab}}" duration="300" bindchange="swiperTab">
<swiper-item><view>第一屏</view></swiper-item>
<swiper-item><view>第二屏</view></swiper-item>
<swiper-item><view>第三屏</view></swiper-item>
</swiper>test.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({
currentTab: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
})
}
}
})test.wxss
.swi {
width: 100%;
height: 100vh;
}
.swiper-tab{
width: 100%;
border-bottom: 2rpx solid #ccc;
text-align: center;
height: 88rpx;
line-height: 88rpx;
font-weight: bold;
}
.swiper-tab-item{
display: inline-block;

}
.active{

border-bottom: 4rpx solid red;
}
