引言
最近一直在研发Nuxt.js聊天项目，有个需求是实现类似探探卡片左右滑动效果。要求四个方向角拖拽出现不同的倾斜视角，左滑unlike|右滑like，并且点击按钮也可以左右切换。
效果图
如上图所示，基本实现了需要的效果。下面就简单分享下实现过程。
页面布局
页面整体分为 顶部导航条、卡片滑动区域、底部标签栏 三个部分。
<!-- //页面模板 -->
<template>
<div>
<!-- >>顶部 -->
<header-bar :back="false" bgcolor="linear-gradient(to right, #00e0a1, #00a1ff)" fixed>
<div slot="title"><i class="iconfont icon-like c-red"></i> <em class="ff-gg">遇见TA</em></div>
<div slot="right" class="ml-30" @click="showFilter = true"><i class="iconfont icon-filter"></i></div>
</header-bar>
<!-- >>主页面 -->
<div class="nuxt__scrollview scrolling flex1" ref="scrollview" style="background: linear-gradient(to right, #00e0a1, #00a1ff);">
<div class="nt__flipcard">
<div class="nt__stack-wrapper">
<flipcard ref="stack" :pages="stackList" @click="handleStackClicked"></flipcard>
</div>
<div class="nt__stack-control flexbox">
<button class="btn-ctrl prev" @click="handleStackPrev"><i class="iconfont icon-unlike "></i></button>
<button class="btn-ctrl next" @click="handleStackNext"><i class="iconfont icon-like "></i></button>
</div>
</div>
</div>
<!-- >>底部tabbar -->
<tab-bar bgcolor="linear-gradient(to right, #00e0a1, #00a1ff)" color="#fff" />
</div>
</template>侧边栏弹框
点击页面右上角筛选按钮，在左侧会出现弹窗。其中 范围滑块、switch开关、star评分 等组件则是使用Vant组件库。

卡片堆叠区单独封装了一个组件flipcard，只需传入pages数据就可以。
pages参数格式
module.exports = [

sex: 'female',
age: 23,
starsign: '天秤座',

</script>由于组件中处理了mouse和touch两种事件，所以支持移动端和pc端拖拽。
