推荐答案

如果您不想使用服务器端解决方案（当然不一定是PHP），最简单的方法是使用数据URI：

If you don't want to use a server-side solution (does not have to be PHP of course), the easiest way is to use a data URI:

data:text/plain,Your text here

这将在浏览器中显示文本文件，并让用户将其保存在他们想要的位置。我不认为有可能为这些类型的URI显示另存为-dialog：

This will show the text file in the browser, and let the user save it where they want. I don't think it's possible to show a "Save as"-dialog for those kind of URI:s.

注意：这至少需要IE8。但我猜这就是你的要求，因为你正在使用localStorage。

Note: this requires IE8 at least. But I'm guessing that's your requirement anyway, since you are using localStorage.
