var fh = fopen(“c:MyFile.txt”, 3); // Open the file for writing

if(fh!=-1) // If the file has been successfully opened
{
var str = “Some text here…”;
fwrite(fh, str); // Write the string to a file

@J2NYCMay 30.2009 — Javascript works on the client side, not the server side. You can't use it to write to the server to my knowledge.

You need to use PHP or another server side tool.

fopen, fwrite, and fclose are php filesystem functions, not javascript functions. You would need to use ajax to communicate with a php script on the server, if you actually want to write files onto the server from javascript (don't know why you would). For info on ajax, see:

Success!
