具体代码如下所示:
<!DOCTYPE html><html> <head> <meta charset=UTF-8> <title>html2canvas_download</title> <style> a { cursor: ponteiro; cor: rgb(85, 26, 139); decoração de texto: sublinhado; } </style> </head> <body> <div id=oDiv style=width: 300px; altura: 300px; margem: 10px; fundo: vermelho; borda: 5px cinza sólido;> <h1>olá mundo!</h1> </div> <!-- <script type=text/javascript src=../dist/html2canvas.js></script> --> <script src=https://cdn.bootcss.com/html2canvas/0.5.0-beta4/html2canvas.min.js></script> <script type=text/javascript> var oDiv = document.getElementById('oDiv'); // body截图 // html2canvas(document.body).then(function(canvas) { // document.body.appendChild(canvas); // }); html2canvas(oDiv).then(function(canvas) { document.body.appendChild(canvas); var oCavans = document.getElementsByTagName('canvas')[0]; var strDataURI = oCavans.toDataURL(); downLoadFn(strDataURI); }); //判断浏览器类型 function myBrowser() { var userAgent = navigator.userAgent; //取得浏览器的userAgent字符串 var isOpera = userAgent.indexOf(Opera) > -1; if(isOpera) { return Ópera }; //判断是否Opera浏览器 if(userAgent.indexOf(Firefox) > -1) { return FF; } //nome do Firefox if(userAgent.indexOf(Chrome) > -1) { return Chrome; } if(userAgent.indexOf(Safari) > -1) { return Safari; } //判断是否Safari浏览器 if(userAgent.indexOf(compatível) > -1 && userAgent.indexOf(MSIE) > -1 && !isOpera) { return IE; }; //判断是否IE浏览器 if(userAgent.indexOf(Trident) > -1) { return Edge; } //判断是否Edge浏览器 } //IE浏览器图片保存本地 function SaveAs5(imgURL) { var oPop = window.open(imgURL, , width=1, height=1, top=5000, left=5000); for(; oPop.document.readyState != completo;) { if(oPop.document.readyState == completo) break; } oPop.document.execCommand(SaveAs); oPop.close(); } // chrome14+,firefox20+,pera15+,Edge 13+,Safari未实现 function download(strDataURI) { var link = document.createElement('a'); link.innerHTML = 'download_canvas_image'; link.download = 'minhapainting.png'; link.addEventListener('clique', function(ev) { link.href = strDataURI; }, falso); document.body.appendChild(ligação); }; function downLoadFn(url) { if(myBrowser() === IE || myBrowser() === Edge) { SaveAs5(url); } else { download(url); } } </script> </body></html>总结以上所述是小编给大家介绍的使用HTML截图并保存为本地图片的实现代码，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对VeVb武林网网站的支持！
