What I want.

I want to be able to autosave a text area after every x minutes and after each time someone edits and stops typing (kinda like Google docs).


I want an HTML/PHP file that (when edited, when a button is pressed, and/or on a timed basis) will save it's <textarea> contents to a file named backup.txt using Ajax/PHP. I want to be able to set the interval in which the document saves.

Requirements/Stuff I want the script to have

  • ONLY use HTML, PHP, JavaScript, and/or jQuery
  • external JS, please no integrated JS
  • I want a PHP file, to save the data to the text file
  • I want a JS file, for the JS/jQuery
  • and I want a HTML/PHP file that has the <textarea> and a save button


  • extra $1 tip if you could integrate CodeMirror. If you choose to implement this, you can place the CodeMirror files in a separate directory or other files.


This would require websockets unless a polling solution is implemented. Websockets can be implemented using a service like Pusher.

Luckily, is free (at first) and easy to set up.

Is this in anyway related to collaborative editing? If not (if it's for just a single user at a time, eg: autosave) you will not need websockets.

It was, but I kinda redid my question, because two people editing one file would to be a mess. My original goal was basically a file editor via PHP/JS.

Download the files here -

delay: 1000,
url: 'save.php',
beforeSave : function() { },
afterSave : function() { }

beforeSave and afterSave are optional and can be used to show and hide a loader when a ajax request is processing :)

Note: you will always need to give an id to your textarea

For a sample check -
