Javascript: Write Console.debug() output to browser?

Question

I need to be able to take any JSON data and print the key/value pairs.

(something similar to print_r() in PHP)

Is this even possible with javascript?

Answer 1

I usually just quickly create a log function that allows you change the logging method. Write enablers/disablers or comment out to choose the options.

function log(msg){
  if (window.console && console.log) {
    console.log(msg); //for firebug
  }
  document.write(msg); //write to screen
  $("#logBox").append(msg); //log to container
}

Update: Info on Firebug's Console API

Update: Added check for non firebug browsers.
