实现步骤

/divscript
export default {
mounted() {// 初始化自适应 ----在刚显示的时候就开始适配一次handleScreenAuto();// 绑定自适应函数 ---防止浏览器栏变化后不再适配window.onresize () handleScreenAuto();
},
deleted() {window.onresize null;
},
methods: {// 数据大屏自适应函数handleScreenAuto() {const designDraftWidth 1920; //设计稿的宽度const designDraftHeight 960; //设计稿的高度// 根据屏幕的变化适配的比例,取短的一边的比例const scale (document.documentElement.clientWidth / document.documentElement.clientHeight) (designDraftWidth / designDraftHeight)? (document.documentElement.clientWidth / designDraftWidth):(document.documentElement.clientHeight / designDraftHeight)// 缩放比例document.querySelector(#screen,).style.transform scale(${scale}) translate(-50%, -50%);}
}
}

/*除了设计稿的宽高是根据您自己的设计稿决定以外其他复制粘贴就完事
*/
.screen-root {height: 100%;width: 100%;.screen {display: inline-block;width: 1920px; //设计稿的宽度height: 960px; //设计稿的高度transform-origin: 0 0;position: absolute;left: 50%;top: 50%;}
}如果你不想分别写htmljs和css那么你也可以使用v-scale-screen插件来帮你完成 使用插件参考https://juejin.cn/post/7075253747567296548
2、使用dataV库推荐使用
vue2版本:http://datav.jiaminghi.com/ vue3版本:https://datav-vue3.netlify.app/
dv-full-screen-containercontent
/dv-full-screen-container优点方便没有留白铺满可视区
3、手写dataV的container容器
嫌麻还是用dataV吧 文件结构 index.vue

/Container 传入你的大屏的分辨率options
