Mr-yang的随笔

首先需要安装插件npm install html2canvas导入插件：import html2canvas from 'html2canvas'事件：downloadImg('jpg')downloadImg('png')逻辑：// 下载图片downloadImg (type) { html2canvas(document.querySelector('需导出的结构类名')).then(canvas => { const url = canvas.toDataUR

copyChart () { // 复制charts为图片 // 获取highcharts的svg图片 const img = new Image() img.src = `data:image/svg+xml;base64,${btoa(unescape(encodeURIComponent(this.getChartSVG())))} ` // 将svg转化为canvas const canvas = document.createElement('canvas') const
