推荐答案

您可以将锚元素的样式设置为类似于按钮，并将其href设置为资产/文件

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>

或动态创建锚元素，将其设置为href元素，然后单击它.

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

类似的东西:

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