Console Helper for Firebug

/ Published in: JavaScript

This comes in handy when working in big objects and you need to see what's happening on the inside of an instance.

I aliased 'console.log' to 'put' and wrapped it in a try/catch block that throws alerts if no console is available. Less typing - and mildly rubyish.

I got the logAllMembers bit from a mailing list archived message - forget the author but props to them. Only alteration I made was to skip null members in the output.

Highlighted TextExpand

/*  use 'put' like this: put('this is a message that will appear in the console');

use 'logAllMembers' like this:
// make a class
FOO.insides = function (){}; 
FOO.insides.prototype = {

count:  10,
  stub:   [],

methodOne: function(args){
    return 'method one';
  }, 
  
  methodTwo: function(args, args2, args3){
    return 'method two'
  } 
};
// create a new instance
bar = new FOO.insides();

bar.stub = ['apple','banana','pear','peach','apple'];

// look inside the instance
logAllMembers(bar);

// will return this:
stub = apple,banana,pear,peach,apple
