前言

 用Vue来写了 移动端 3D轮播 带缩略图  ,在加 动画翻卡效果  ，其实也不是太难吧，也就做了一下午，哈哈，

 船到桥头自然直，这样才可以，

首先看下做好的效果图

 

 

 

 可以 点击 滑动 ，可以触摸滑动， 可以点击 缩略图滑动， 最后 在点击那个 选中的 翻卡的 那个有翻卡 的3D效果

代码：

<template>
  <section class="container">
    <div id="slide" class="slide index-slide">
      <!-- 轮播图片数量可自行增减 -->
      <div
        class="img back"
        v-for="(item,index) in imgsList"
        :key="index + '-img'"
        :class="'img'+ (index+1) "
        :ref="'imgs'+(index)"
        :id="'img'+(index)"
      >
        <img :src="item.img" :ref="'innderImgs'+(index)">
      </div>
      <div
        class="img front"
        v-for="(item,index) in imgFront"
        :key="index"
        :class="'img'+ (index+1) "
        :ref="'img'+(index)"
        :id="(index)"
        @click="clickFan(index) "
      >
        <img :src="item" :ref="'innderImg'+(index)">
      </div>
    </div>
    <div class="slide-bt">
      <img
        :src="item.img"
        v-for="(item,index) in imgsList"
        :key="index"

翻卡：

原理:这个卡片翻转效果是利用背面的内容一开始就先翻转180度,等正面翻转的时候背面再翻转360度,这样子背面翻转到面对屏幕的时候内容却是正的而不是反的

代码解析:

这里主要用到了CSS3的一些新的属性:perspective;

　　　　　　　　　　　　　　　　　　backface-visibility:hidden;

　　　　　　　　　　　　　　　　　　transition:all 2s;

　　　　　　　　　　　　　　　　　　transform:rotateY(Ndeg);

下面对这些属性进行详细的说明.

1.perspective:number|none(默认)

主要用来表示3D元素距离视图的距离,单位是像素,定义在父元素上,子元素就会获得透视效果,目前浏览器都在不支持,chrom和safari支持扩展的-webkit-perspectiv.

这个属性能查到的资料上基本上都是这么讲的,感觉不是很理解什么事透视效果,在我看来,使用这个属性就是在3D转换的时候能够看到立体的3D效果,可以配合perspective-origion来使用,可惜的是目前只有chrom和safari支持带有浏览器属性前缀的该属性.

2.backface-visibility:visiale|hidden

该属性用来定义当元素不面向屏幕的时候是否可见,可用来设置旋转元素是否希望用来看到背面.IE10+和Firefox支持该属性,Opera 15+、Safari 和 Chrome 支持替代的 -webkit-backface-visibility 属性

3.transition:css属性名称 完成动画的时间 规定速度效果的速度曲线 定义过渡效果何时开始

transition是一个简写属性,用来设置四个属性:transition-property, transition-duration, transition-timing-function, transition-delay,一般为了省事直接就会写作transition:all 2s。过渡时间必须设置，否则不会产生过渡效果。IE10+,chrome,opera,Firefox支持transition属性,Safari支持替代的-webkit-transition属性

transition-timing-function:linear(匀速)|ease(默认.慢速开始,加快,慢速结束)|ease-in(慢速开始)|ease-out(慢速结束)|ease-in-out(慢速开始,慢速结束)|cubic-bezier(n,n,n,n)贝赛尔曲线

4.transform:rotateY(Ndeg)

兼容性不说那么多了,感觉反正用的时候全部加上浏览器前缀好啦.

主要是用来定义各种变换的,translate,scale,rotate,skew,可惜熟悉使用一下,用的还是比较多的

 

这就是 2019年最后一遍博客啦，

来年咱们继续加油呀 ，奋斗的少年
