答

您可以将锚元素的样式设置为看起来像按钮，并将其 href 设置为 assets/file

You can either style an anchor element to look like a button and set it's href to assets/file

<a href="assets/file">Download here</a>

或者动态创建一个锚元素，设置它的 href 元素并点击它.

Or create an anchor element on the fly, set it's href element and click it.

类似于:

let link = document.createElement('a');
link.setAttribute('type', 'hidden');
link.href = 'assets/file';
link.download = path;
document.body.appendChild(link);
link.click();
link.remove();
