Is it possible to edit a local file without uploading to the b开发者_开发知识库rowser?

Let's say the client has an HTML file, I want him to be able to use my site's javascript to edit the file without uploading it. Would this be possible?

Thanks.

Yes, it is possible, but only in HTML5 (and only as browsers add support for it...not all do yet), you can find the HTML5 File API here.

Note that the user has to give permission to access the file, from Section 5.9:

Once a user has given permission, user agents should provide the ability to read and parse data directly from a local file programmatically.

Nope, that's not possible and shouldn't be either due to security concerns it may pose otherwise.

Note: This feature is there in HTML5 as pointed out by @Nick Craver, you may want to go for but you should be aware of the fact that HTML5 isn't yet supported by all browsers.
