How to write to an external file when running JS under Linux?

[caddie]

Hi,

The following is a javascript code snippet to write to a file.

------------------------------------------------------
var fso, t;
fso = new ActiveXObject("Scripting.FileSystemObject");
t = fso.CreateFolder("C:\\file.txt", true);
t.writeline("Testing");
t.Close();
-------------------------------------------------------

However this is for Windows platform. Does anyone know if there is an equivalent method using Linux?

Thanks for your help.

It's not a "Windows thing", it's an "Internet Explorer thing". It wouldn't work under Firefox, Opera, or Safari for Windows.

While you can use some java.io.File.* routines in Firefox (e.g. to find the size of a file), things like writing to a file would (as far as I know) be restricted for security reasons.

It's possibe that if you were using a signed script of some sort, then it would work. Take a read here for more on these:

Just in case you do go down this route, try something like this:

var theFilename = 'C:\\file.txt';
var theData = 'Testing';

if (window.ActiveXObject) {
	try {
		var fileObj = new ActiveXObject('Scripting.FileSystemObject');
		var t = fileObj.CreateTextFile(theFilename, true);
		t.WriteLine(theData);
		t.Close();
	} catch(e) {
		alert('There was an error writing your file.\n\n' + e);
	}
} else {
	try {
		var fileObj = new java.io.PrintWriter(new java.io.FileWriter(theFilename));
		fileObj.println(theData);
		fileObj.close();
	} catch(e) {
		alert('There was an error writing your file.\n\n' + e);
	}
}

I've not tested it, but you never know - it might just work!

Incidentally, I switched your usage of "CreateFolder" for "CreateTextFile", and "writeline" for "WriteLine".

Hope this helps,
