推荐答案

你不能在客户端机器中创建文件夹。但是使用ActiveX，你可以。在IE中也是如此..

正确说明下载发生在客户端！因此，您拥有的唯一代码就是页面内有下载按钮的内容 - JavaScript ...

出于安全原因，JavaScript无法访问客户端的计算机而您无法设置目标文件夹下载 - 这是用户必须选择的东西......

As you properly states download occurs in client side! AS such the only code you have there is what inside your page with the download button - JavaScript...
For security reasons JavaScript can not access the clients' machine and you can not set the target folder for downloading - it's something the user have to choose...

这是不允许的，这是出于安全原因。如果任何 Web App 将操纵文件系统，那么它将对计算机构成风险，因为它可能会对计算机造成伤害。



所以，简单地说，不要这样做。用户应该优先选择文件夹，他/她可以保存文件。

This is not allowed and it is for security reasons. If any Web App will manipulate the File System, then it will be risk to computer as it can do harm to computer if possible.

So, simply, don't do this. User should get the preference of choosing the folder, where he/she can save the file.
