file i/o with javascript

from reading some previous posts, i noticed that javascript does not have any real file output. however i have heard that there is a way to make an applet do the file stream work. if anyone knows how to do this, could you let me know.

as far as i know if you are using javascript client side (or an applet in your browser) you cannot use direct file i/o on any of the users files as this would SERIOUSLY compromise security.

you need to get the user to run an exe of some form to do file i/o.

if you are running it server side then file i/o is not a problem as the scripting engine will take care of it. look at http://msdn.microsoft.com/scripting/ for the jscript reference.

bye dude

There is, however some file i/o capbilities with client side VBscript. As far as Javascript, you can read .txt, .html, .js and a few other file types in IE4+ using this method:

1) Create a frame. Pretend its called "textFrame". The source should be the file you wish to read. NOTE: It CANNOT be an <iframe>.

2) You can read the contents of the page from a different frame like so:

var string = parent.textFrame.document.body.innerHTML;

alert(string);

*As far as I know, that is the extent of any kind of file handling with JavaScript.
