Read a local file

Is there no way for javascript hosted on a webserver to read a 开发者_如何学Gofile on a client's local machine? (this has obvious security risks). I guess I'm wondering if there's any access granting a user can do, like drag and dropping a file into the browser, or explicitly selecting a file from a popup to get around this?

I know flash 10 allows reading of a local file, just wondering if there were any method to do this in javascript.

Thanks

... or explicitly selecting a file from a popup to get around this ...

You could of course just upload the file to your server then...

Who on their right mind would release a browser that let JS to... oh wait, you can with activeX, but only works with IE.

There is new File API being a working draft in W3C, and it is already implemented in Firefox 3.6, see

Nope, that's not possible...

However, see this:
