如何在下载之前强制打开文件浏览器以保存文件？ [英] How to forcefully open the file browser to save the file before downloading?

问题描述

我希望我的Chrome浏览器强制打开用于下载的对话框（即另存为）。无需手动更改Chrome浏览器中的下载设置。
有没有办法使用angular js或javascript？

OR

强制chrome浏览器打开文件浏览器，在使用JavaScript和/或AngularJs下载文件之前询问要保存文件的位置？ 欢迎来到所以！

由于安全原因，无法执行您的建议。您无权选择文件在其操作系统上的位置。 JS不会比用户的浏览器更深入。您所要求的基本上是FS（文件系统）读写权限。

在提出新问题之前，请务必做一些四处搜寻，因为这个问题已经存在在这里回答： HTML页面中的目录选择器

解决方案

Welcome to SO!

There is no way to do what you're suggesting for security reasons. You don't have rights to choose where the file will go on their OS. JS won't go any deeper than the user's browser. What your asking for is essentially FS (file system) read-write permissions.

Make sure to do a little searching around before you ask new questions, as this one was already answered here: Directory Chooser in HTML page
