vue3 寫一個大屏

前面寫了一篇vue3.0的基本上手的文章，今天來個偏向實戰的，寫兩個大屏demo，沒有設計稿參考了一個別人寫的HTML版的，一些邊框裝飾我用了DataV這個庫，這兒也放上這兩個的地址。

1rem = 100px

佈局方面同過vw,vh flex 彈性盒子進行佈局

封裝元件

main.js 中註冊echarts 配置到全域性呼叫，vue2.x中就是掛載到原型鏈上，我把全域性元件自動註冊了，統一把components下的元件都作為全域性元件使用，使用require.context 遍歷註冊

app.config.globalProperties.echarts = echartsconst vueFiles = require.context(&#34;@/components&#34;, true, /component\\.vue$/)vueFiles.keys().forEach((key) =&gt; { const component = vueFiles(key).default app.component(component.name, component)})const jsFiles = require.context(&#34;@/components&#34;, true, /component\\.js$/)jsFiles.keys().forEach((key) =&gt; { const component = jsFiles(key).default app.component(component.name, component)})

components 新增tao-charts元件

&lt;template&gt; &lt;div ref=&#34;myChart&#34; class=&#34;echarts&#34;&gt;&lt;/div&gt;&lt;/template&gt;&lt;script&gt;import { onMounted, getCurrentInstance } from &#34;vue&#34;export default { name: &#34;tao-charts&#34;, props: { data: { type: Object, default: null } }, setup(props) { const { ctx } = getCurrentInstance() const drawLine = (dom, option) =&gt; { const myChart = ctx.echarts.init(dom) myChart.setOption(option) // 當瀏覽器視窗發生變化的時候呼叫div的resize方法 window.onresize = () =&gt; { myChart.resize() } } const setChart = (option) =&gt; { const dom = ctx.$refs.myChart drawLine(dom, option) } onMounted(() =&gt; { setChart(props.data) }) }}&lt;/script&gt;&lt;style lang=&#34;scss&#34; scoped&gt;.echarts { height: 100%; width: 100%; position: relative;}&lt;/style&gt;

呼叫元件圖表配置項

效果預覽總結

上面的程式碼只是部分，完整程式碼我也上傳到碼雲上面了，需要說明下，所有的資料都是隨便造的，具體細節也沒有調，只是作為個demo，如果想要完整的程式碼碼雲上搜索upholdjx/vue-datav-chart就可以找到了

下面展示幾張上面提到的別人寫的HTML版本的一些樣例，感覺挺不錯有需要的可以去看看，地址在開頭也說了。
