推荐答案
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();
