暂未完赛，请继续加油吧-

测试截图 ``` function getScreenShot(){ html2canvas(document.querySelector("#canvas")).then(canvas => { // document.body.appendChild(canvas) var t = canvas.toDataURL().replace("data:image/png;base64,", ""); downloadBase64File('image/png',t,'image'); }); } function downloadBase64File(contentType, base64Data, fileName) { const linkSource = `data:${contentType};base64,${base64Data}`; const downloadLink = document.createElement("a"); downloadLink.href = linkSource; downloadLink.download = fileName; downloadLink.click(); } ```
