屏幕分辨率适配方案
这里就不再过多举例了，通过这四张图可以看出来页面布局并没有受到过多的影响，所以直接上代码，cv就完事了

首先下载lodash插件

 npm i lodash -S

然后在App. vue 中导入，此处的App.vue主要指的是主框架，因不同项目可自行选择

  import _ from 'lodash'

然后给app容器挂上 ref=“app”

<template>
    <div id="app" ref="app">
      <router-view />
    </div>
</template>

然后在 mounted 使用如下方法（其中的1920以及1080为定义的画布尺寸）

<script>
import _ from "lodash";
export default {
  name: "App",
  mounted() {
    this.$nextTick(() => {
      const $app = this.$refs.app;
      // 设置 屏幕 百分比 尺寸 适配
      const standardScale = "100%" / "100%";
 
      window.addEventListener(
        "resize",
        _.debounce(function () {
          const docHeight = document.body.clientHeight;
          const docWidth = document.body.clientWidth;
 
          if (docWidth < 1680) {
            const currentScale = docHeight / docWidth;
            let [scale, translate] = [0, 0];
            if (currentScale < standardScale) {
              // 以高度计算
              scale = docHeight / 1080;
              const shouleWidth = 1920 * scale;
         
              const offsetWidth = docWidth - shouleWidth;
              translate =
                offsetWidth > 0 ? `translate(${offsetWidth / 2}px, 0)` : "";
            } else {
              // 以宽度计算
              scale = docWidth / 1920;
              const shouleHeight = 1080 * scale;
              const offsetHeight = docHeight - shouleHeight;
              translate =
                offsetHeight > 0 ? `translate(0, ${offsetHeight / 2}px)` : "";
            }
            console.log(translate);
            $app.style.cssText = `
            transform: scale(${scale}) ${translate};
            transform-origin: top left;
            min-width: 1920px;
            min-height: 1080px;
          `;
          } else {
            $app.style.cssText = "";
          }
        }),
        300
      );
 
      if (document.createEvent) {
        var event = document.createEvent("HTMLEvents");
        event.initEvent("resize", true, true);
        window.dispatchEvent(event);
      } else if (document.createEventObject) {
        window.fireEvent("onresize");
      }
    });
  },
};
