1、 toggleFullscreen方法实现选定元素全屏展示
2、使用flex属性+ flex-direction 实现垂直布局填满整个页面
<template> <div id="aaa" class="container"> <div class="header"> <el-button @click="toggleFullscreen">全屏</el-button> </div> <div class="content"> <div style="display: flex;height: 100%"> <el-table :data="countData" border style="width: 30%" height="88%"> <el-table-column label="线体" prop="prolineCode" align="center" min-width="120px" /> <el-table-column label="点检异常次数" prop="count" align="center" min-width="120px" /> </el-table> <div id="bbb" style="width: 70%; height: 100%"></div> </div> </div> </div></template><script>import { ref, onMounted, onUnmounted } from 'vue'import * as echarts from 'echarts'export default { name: 'App', setup() { const countData = ref([]) onMounted(() => { initChart() // initChart1() }) onUnmounted(() => { }) const initChart = () => { var chartDom = document.getElementById('bbb') let myChart = echarts.getInstanceByDom(chartDom); if (myChart) { myChart.dispose(); } myChart = echarts.init(chartDom); var option = { xAxis: { type: 'category', data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] }, yAxis: { type: 'value' }, series: [ { data: [820, 932, 901, 934, 1290, 1330, 1320], type: 'line', smooth: true } ] } option && myChart.setOption(option) window.addEventListener('resize', function () { myChart.resize() }) } const initChart1 = () => { var chartDom = document.getElementById('ccc') let myChart = echarts.getInstanceByDom(chartDom); if (myChart) { myChart.dispose(); } myChart = echarts.init(chartDom); var option = { xAxis: { type: 'category', data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] }, yAxis: { type: 'value' }, series: [ { data: [820, 932, 901, 934, 1290, 1330, 1320], type: 'line', smooth: true } ] } option && myChart.setOption(option) window.addEventListener('resize', function () { myChart.resize() }) } const toggleFullscreen = () => { const element = document.getElementById('aaa') if (element) { if (document.fullscreenElement) { document.exitFullscreen(); } else { element.requestFullscreen() .catch(err => { console.log('无法进入全屏模式:', err) }) } } } return { countData, toggleFullscreen } }}</script><style>body { margin: 0;}/* 使用flex布局 */.container { display: flex; flex-direction: column; height: 100vh; /* 确保容器元素的高度与视口高度一致 */}/* 设置上部元素 */.header { border: 1px solid green; height: 100px; /* 上部元素的高度 */ background-color: #ccc; /* 上部元素的样式 */}/* 设置下部元素 */.content { border: 1px solid yellow; flex-grow: 1; /* 下部元素占据父元素的剩余空间 */ background-color: #eee; /* 下部元素的样式 */}</style>
