微信小程序简单实现手势左右滑动和点击滑动步骤条功能

使用微信小程序实现左右滑动功能，自定义顶部图案，点击文字滑动和手势触屏滑动，功能简单，具体实现代码如下所示：
滑动示例

1、wxss代码：

/* 步骤条 */
.tab-box {display: flex;flex-direction: row;position: fixed;left: 0;right: 0;top: 0;z-index: 999;background-color: #EEEEEE;padding: 15rpx 20rpx;
}.radius-a {width: 34%;border-radius: 5rpx 0 0 5rpx;
}.width-2{width: 28%;
}.radius-b {width: 28%;border-radius: 0 5rpx 5rpx 0;
}.rule-a {height: 80rpx;background-color: #44ADFB;color: white;line-height: 80rpx;text-align: center;font-size: 32rpx;font-weight: bold;
}.rule-b {width: 0;height: 0;border-top: 40rpx solid transparent;border-bottom: 40rpx solid transparent;border-left: 20rpx solid #44ADFB;
}.rule-c {position: relative;width: 0;height: 0;border-left: 40rpx solid transparent;border-bottom: 80rpx solid #44ADFB;
}.rule-c::after {content: "";position: absolute;top: 0;left: -40rpx;width: 0;height: 0;border-left: 40rpx solid transparent;border-top: 80rpx solid #44ADFB;
}.blue {color: #fff;background-color: #44ADFB;
}.gray {color: #606266;
}.box{margin-top: 120rpx;text-align: center;font-size: 32rpx;
}

2、wxml代码：

<view class="tab-box"><view class="rule-a radius-a {{currentVal == 0 ? 'blue' : 'gray'}}" bindtap="changeTabs" data-index="0">第一步</view><view class="rule-b"></view><view class="rule-c"></view><view class="rule-a width-2 {{currentVal == 1 ? 'blue' : 'gray'}}" bindtap="changeTabs" data-index="1">第二步</view><view class="rule-b"></view><view class="rule-c"></view><view class="rule-a radius-b {{currentVal == 2 ? 'blue' : 'gray'}}" bindtap="changeTabs" data-index="2">第三步</view>
</view>
<view class="box"><swiper current="{{currentVal}}" circular="true" bindchange="swiperChang"><!--第一步 --><swiper-item>示例一界面内容</swiper-item><!-- 第二步 --><swiper-item>示例二界面内容</swiper-item><!-- 第三步 --><swiper-item>示例三界面内容</swiper-item></swiper>
</view>

3、js代码：

Page({/*** 页面的初始数据*/data: {currentVal: 0,},//点击顶部tab切换changeTabs: function (e) {this.setData({currentVal: e.currentTarget.dataset.index});},// 滑动监听swiperChang: function (e) {this.setData({currentVal: e.detail.current});},
})
