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

javascript, json, loops

Solution

Yes, you can process a surprising amount of info through alert, and you can also use it for debugging.

Here is a print_r equivalent for javascript also.

function print_r(theObj){
  if(theObj.constructor == Array ||
     theObj.constructor == Object){
    document.write("<ul>")
    for(var p in theObj){
      if(theObj[p].constructor == Array||
         theObj[p].constructor == Object){
document.write("<li>["+p+"] => "+typeof(theObj)+"</li>");
        document.write("<ul>")
        print_r(theObj[p]);
        document.write("</ul>")
      } else {
document.write("<li>["+p+"] => "+theObj[p]+"</li>");
      }
    }
    document.write("</ul>")
  }
}

good luck with your project!

Problem

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?
