<view class="swiper-tab">  
    <view class="swiper-tab-list {{currentTab==0 ? &#39;on&#39; : &#39;&#39;}}" data-current="0" bindtap="swichNav">tab一</view>  
    <view class="swiper-tab-list {{currentTab==1 ? &#39;on&#39; : &#39;&#39;}}" data-current="1" bindtap="swichNav">tab二</view>  
    <view class="swiper-tab-list {{currentTab==2 ? &#39;on&#39; : &#39;&#39;}}" data-current="2" bindtap="swichNav">tab三</view>  
</view>  
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">  
    <!-- tab一 -->  
    <swiper-item>  
      <view>tab一</view>  
    </swiper-item>  
    <!-- tab二 -->  
    <swiper-item>  
      <view>tab二</view>  
    </swiper-item>  
    <!-- tab三 -->  
    <swiper-item>  
      <view>tab三</view>  
    </swiper-item>  
</swiper>

2.Set data: swipertab.js

//获取应用实例  
var app = getApp()
Page({
	data: {
		/** 
		 * 页面配置
		 */
		winWidth: 0,
		winHeight: 0,
		// tab切换  
		currentTab: 0,
	},
	onLoad: function() {
		var that = this;

		/** 
		 * 获取系统信息
		 */
		wx.getSystemInfo({

			success: function(res) {
				that.setData({
					winWidth: res.windowWidth,
					winHeight: res.windowHeight
				});
			}

		});
	},
	/** 
	 * 滑动切换tab
	 */
	bindChange: function(e) {

		var that = this;
		that.setData({
			currentTab: e.detail.current
		});

	},
	/** 
	 * 点击tab切换
	 */
	swichNav: function(e) {

		var that = this;

		if (this.data.currentTab === e.target.dataset.current) {
			return false;
		} else {
			that.setData({
				currentTab: e.target.dataset.current
			})
		}
	}
})

3. Set style: swipertab.wxss

.swiper-tab{  
    width: 100%;  
    border-bottom: 2rpx solid #777777;  
    text-align: center;  
    line-height: 80rpx;}  
.swiper-tab-list{  font-size: 30rpx;  
    display: inline-block;  
    width: 33.33%;  
    color: #777777;  
}  
.on{ color: #da7c0c;  
    border-bottom: 5rpx solid #da7c0c;}  
  
.swiper-box{ display: block; height: 100%; width: 100%; overflow: hidden; }  
.swiper-box view{  
    text-align: center;  
}
