javascript - Highcharts:如何在window.location.href中指定文件名将图像导出到本地磁盘

Question

This jsfiddle显示如何将 Highcharts 图表导出到 png 文件，但不显示如何指定文件名。

类似

var image = canvas.toDataURL("image/png")
            .replace("image/png", "image/octet-stream"); 

image.filename = "file.png";    <=== this doesn't work

// Save locally
window.location.href = image;

有什么想法吗？

Answer 1

var image = Canvas.toDataURL("image/png").replace("image/png", "image/octet-stream"); window.location.href=图像；//它将保存在本地
