推荐答案

JavaScript无法访问文件系统，无法使用Ajax下载文件.尝试使用指向文件的iframe进行下载.

Javascript cannot access file system, you cannot use ajax to download files. Try using an iframe pointing to the file to download it.

<iframe id="downloadFrame" style="display:none"/>

当您需要下载时，请使用以下脚本:

When you need to download, use this script:

var iframe = document.getElementById("downloadFrame");
iframe.src = "yourpathtofile";

如果您使用jQuery，则可以尝试:

If you use jQuery, you can try:

$("#downloadFrame").attr("src","yourpathtofile");

另一种解决方案是使用window.open

Another solution is using window.open

window.open("pathtoyourfle");
