href="#从0实现一个年度报告" aria-label="Permalink to "从0实现一个年度报告""></a></h1><p>每到年底各大应用都会推出自己的年终总结报告，统计出用户一年来在应用内的行为展示给用户，供用户记录、分享。</p><p>今年掘金社区推出了自己的<a href="https://zjsms.com/hbdA5jR" target="_blank" rel="noreferrer">2022掘友年度报告</a>，这次我们仿照这个报告，从0开始自己实现一个年终总结报告页面</p><h2 id="实现难点" tabindex="-1">实现难点 <a class="header-anchor" href="#实现难点" aria-label="Permalink to "实现难点""></a></h2><h3 id="_1-数据模拟" tabindex="-1">1. 数据模拟 <a class="header-anchor" href="#_1-数据模拟" aria-label="Permalink to "1. 数据模拟""></a></h3><p>一般情况下是根据用户UID，到后端去请求相关接口获得统计数据。</p><p>例如掘金的接口为<code>https://api.juejin.cn/event_api/v1/annual/annual_summary?aid=xxxxxx</code></p><p>本次后端使用<code>NodeJS</code>实现了一个爬虫，可以将用户数据统计完成后导出JSON格式的数据，将此数据粘贴到前端页面的输入框即可生成自己的报告</p><h3 id="_2-屏幕适配" tabindex="-1">2. 屏幕适配 <a class="header-anchor" href="#_2-屏幕适配" aria-label="Permalink to "2. 屏幕适配""></a></h3><p>可以观察到，在PC端和在手机端访问年度报告展示的效果是不一样的。</p><p>本次考虑使用媒体查询来实现这个功能：</p><ul><li>宽屏则展示背景，页面切换也使用背景中的上下切换按钮</li><li>小屏则隐藏背景，让内容填满屏幕，页面切换通过滑动事件监听</li></ul><h3 id="_3-动画效果" tabindex="-1">3. 动画效果 <a class="header-anchor" href="#_3-动画效果" aria-label="Permalink to "3. 动画效果""></a></h3><p>动画分为文本与背景元素的动画</p><ul><li>背景元素的动画使用了SVG动画 <ul><li>动画中不动的部分直接使用<code>.png</code>图片</li><li>运动的部分使用SVG动画绘制，如克里克的眼睛、尾巴</li></ul></li><li>文本的动画使用了<code>CSS Animation</code>渐显的效果 <ul><li>不同段落之间通过<code>animation-delay</code>属性，彼此相差<code>1000ms</code></li></ul></li></ul><p>背景动画容器的四个位置：<code>左上角</code> <code>右下角</code> <code>中间部分</code> <code>中间（悬浮气泡）</code>。不同位置的动画容器都采用绝对定位<code>position: absolute;</code>，辅以<code>z-index</code>实现层叠</p><p>囿于工期，本次的背景动画直接采用静态图片+<code>CSS Animation</code>实现上下浮动的效果</p><h3 id="_4-音乐播放" tabindex="-1">4.
