Javascript Highcharts：如何在window.location.href中将图像导出到本地磁盘中指定文件名

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

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;

差不多

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？

var image=Canvas.toDataURLimage/png.replaceimage/png，image/octet-stream；

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;

---

window.location.href=image；//它将在本地保存

这是发布的答案，您试过了吗？

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;
