File Editing

MattLeek · February 17th, 2004, 12:29 PM

Hello,
Is it possible to edit files on a server with Javascript. If it is, could i do it on a remote server? For example i want to change just 5 numbers that are stored in it (highscores).

Thanks

What exactly do you want to do? Do you want to edit a file on a different machine using client side script or use server side script to edit a file on the same server?

Ok, i haven't really been doing this for long (a few hours really), but so far i have a page that uses asp to get the name and score that has been put in the url by the program. I then want to check their score against one stored on a different page and if it is higher, write over the original score.

I hope this helps

Sounds like you want to use server side script then. Lets say you have an asp page that receives this url:

Code:

www.games.co.uk/myScores.asp?name=joe&score=100

.
In the asp page you have code (you said to use JavaScript):

Code:

var sName = Request("name") + "";
var iScore = parseInt(Request("score") + "", 10);

Now you also have a text file, stored in the same folder as the asp page. This file is name after the user, <username>.txt, and has their previous score

Code:

var ForReading = 1;
var ForWriting = 2;
var sFileName = Server.MapPath(sName + ".txt");
var oFso = new ActiveXObject("Scripting.FileSystemObject");
if (oFso.fileExists(sFileName))
{
  var oTS = oFso.OpenTextFile(sFileName, ForReading);
  var iLastScore = oTS.readLine();
  oTS.close();
  iLastScore = parseInt(iLastScore, 10);
  if (iLastScore < iScore)
  {
    oTS = oFso.OpenTextFile(sFileName, ForWriting);
    oTS.writeLine(iScore);
    oTS.close();
  }
}
else
{
  //Something wrong?
}

You can look at more on FileSystemObject on msdn.com. For example if the file does not exist because it's their first game you can create it from scratch.
