指定保存html2canvas到本地的文件名

Question

所以，我已经设法使用 html2canvas 以编程方式保存文件并且它设法保存了文件。但是，我想指定渲染图像的名称，而不是将其保存为 "download"。那可能吗？我目前的实现方式如下：

html2canvas(document.body, {
    onrendered: function(canvas) {
        var image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream");  // here is the most important part because if you dont replace you will get a DOM 18 exception.
        window.location.href=image;
    }
});

Answer 1

html2canvas(document.body, {
    onrendered: function(canvas) {
        var image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream");  // here is the most important part because if you dont replace you will get a DOM 18 exception.
        var a = document.createElement('a');
         a.href = image;
         a.download = 'somefilename.png';
         a.click();
    }
});
