// 最近用到一个保存html为图片到本地的功能(保存到下载目录),记之,该功能IE使用Blob 存储数据,关于兼容性问题参见如下表格,其他浏览器使用a标签download属性新功能下载
Browser | Constructs as | Filenames | Max Blob Size | Dependencies |
---|---|---|---|---|
Firefox 20+ | Blob | Yes | 800 MiB | None |
Firefox < 20 | data: URI | No | n/a | Blob.js |
Chrome | Blob | Yes | 500 MiB | None |
Chrome for Android | Blob | Yes | 500 MiB | None |
Edge | Blob | Yes | ? | None |
IE 10+ | Blob | Yes | 600 MiB | None |
Opera 15+ | Blob | Yes | 500 MiB | None |
Opera < 15 | data: URI | No | n/a | Blob.js |
Safari 6.1+* | Blob | No | ? | None |
Safari < 6 | data: URI | No | n/a | Blob.js |
// 步骤一:引入html2canvas.js
//步骤二:完成以下方法即可
function downloadForJS(){
//使用html2canvas 转换html为canvas
html2canvas($("#ID")).then(function(canvas) {
if(IE){ //判断IE下保存方法
var blob = canvas.msToBlob();
window.navigator.msSaveBlob(blob, fileName);
}else{//其他浏览器保存方法
var imgUri = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream"); // 获取生成的图片的url
var saveLink = document.createElement( ‘a‘);
saveLink.href =imgUri;
saveLink.download = fileName; saveLink.click();
}
});
}
