    <view class="swiper-tab-item {{currentTab==1?'active':''}}" data-current="1" bindtap="clickTab">中奖view>
    <view class="swiper-tab-item {{currentTab==2?'active':''}}" data-current="2" bindtap="clickTab">未中奖view>
view>

<swiper current="{{currentTab}}" duration="300" bindchange="swiperTab">
    <swiper-item>
        <view>全部view>
    swiper-item>
    <swiper-item>
        <view>中奖view>
    swiper-item>
    <swiper-item>
        <view>未中奖view>
    swiper-item>
swiper>

.swiper-tab {

tab.js：

Page({

        // 页面初始化 options为页面跳转所带来的参数
    },

    //滑动切换
    swiperTab: function (e) {

        this.setData({
            currentTab: e.detail.current
        }); 
    },

    //点击切换
    clickTab: function (e) {
        if (this.data.currentTab === e.target.dataset.current) {
            return false;
        } else {
            this.setData({
                currentTab: e.target.dataset.current
            })
        }
