I have a textarea that limits the input to 300 characters.  I want to capture the keypress count and show the user how many characters they used of the 300 ie "You have used 150 of 300 characters".  I found some code to capture the keypress count, but don't know how to set the character count in a separate text input box. I tried to use the val function to set the value, but it takes only a string. 
Thanks for any help.

$(document).ready(function()
   {
     $('#info').keypress(function()
       {
        //alert('Handler for .keypress() called.');
        * set a text input field called CountDown  here increasing with each keypress as in i++
       });
  });
