You can use ajax to request the file from the server and then in the success callback you can process the file contentsjasonscript– jasonscript2013-10-14 09:27:31 +00:00Commented Oct 14, 2013 at 9:27

Why write to a text file and not a database? Think about what will happen when multiple people are running the code, you'll end up locking the file.Jeremy Thompson– Jeremy Thompson2013-10-14 09:29:37 +00:00Commented Oct 14, 2013 at 9:29

It is not possible to edit server sided files using pure Javascript, imagine the security issues :)
What you could do is to use a server sided language, like PHP or ASP, and send an ajax request to the server containing the information you want to write.

JavaScript is client-side language, so it don't have access to server. To do it you have to use AJAX and some server-side language, eg. PHP to handle requests.

ya i thought of it but since i was not allowed to use PHP i tried using SHELL instead and it worked thanks..
You can read a file with javascript via an AJAX call. You cannot save a file with javaScript. You will need a server side language like PHP.
You can use: step 1) jquery to load a file: http://api.jquery.com/load/ step 2) jquery to send the modified text to the .php : script http://api.jquery.com/jQuery.post/ step 2.1) save the data in php : http://php.net/manual/en/function.file-put-contents.php

$.getJson("/main.txt",function(jsonObject){
// your logic;
})
