Saving local files in javascript under Opera

[André Wagner]

Hello,

I'm writing a HTML/javascript application who will run locally. I want
to save to a local file.

If I were using IE, I would do this way:

var fso = new ActiveXObject("Scripting.FileSystemObject");
var file = fso.OpenTextFile(filePath,2,-1,0);
file.Write(content);
file.Close();

If I were using Mozilla, I would do like this:
netscape.security.PrivilegeManager.enablePrivilege ("UniversalXPConnect");
var file =
Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile );
file.initWithPath(filePath);
if (!file.exists()) file.create(0, 0664);
var out =
Components.classes["@mozilla.org/network/file-output-stream;1"].createInstance(Components.interfaces.nsIFileOutpu tStream);
out.init(file, 0x20 | 0x02, 00004,null);
out.write(content, content.length);
out.flush();
out.close();

But I couldn't figure out how to do it using Opera. Does anyone has any
idea?

Thank you in advance,

André

Check out TwiddlyWiki (google to find it). They use Java through
Livescript to access files. It needs configuration to allow that, but
it works.

Which becomes easier if I write the name correctly: TiddlyWiki!
For some reason, my ISP is acting up, so I can't google for it myself :(

You could try it using LiveConnect making JavaScript to Java calls. But
I am not sure that works, it might cause Java security exceptions.
