javascript keylogger

Pure JS, no JQuery

The goal is to create [login to view URL] file that will do the following

You can include it in any exitsing webpage

<script src=”[login to view URL]”></script>

There are 2 manners to init it:

In input type=”text” or textarea as propriety

<input type=”text” id =”input1” keylogger”>

<input type=”text” id =”input2””>

<textarea id=”textarea1”></textarea>




Then the script will spy the input or textarea and will store on each keypress

Ex: an user types in “hello”:

{session:1, inputid:’#input2’, time: 0, dif: ‘+h’}

{session:1, inputid:’#input2’, time: 120, dif: ‘+e’}

{session:1, inputid:’#input2’, time: 1500, dif: ‘+l’}

{session:1, inputid:’#input2’, time: 1900, dif: ‘+l’}

{session:1, inputid:’#input2’, time: 3500, dif: ‘+o’}

session: just a number (ex: 1)

inputid: is the input id

time : is the time in milliseconds where change occurs

dif: is the text difference storage.

Save (ajax post) these datas to mysql database

The difficulty would be : store the difference of texts between 2 keypress:

Ex: an user deletes some text or put the cursor in middle on text and inserts a char

Some interesting “text difference” libraries:

Ex: [login to view URL]

Since input make be long (many kilos), we cannot store the whole value of the input, but only the text differences between 2 keystrokes.

Second PART

Then once we have the data saved, we should be able to “play it back” including the time changes, by loading the session data (ex: session1)

So if the input takes 10 seconds, it should least 10 second on playBack as well


Also include a slider so user can move inside timeline

ex: So if the input takes 90 seconds, it should least 90 second on playBack; however user can move with his slider directly to second; 45 or second 90.
