JS to list methods / properties on a javascript object

js_list_props.js

var obj = document.getElementById('flashObj');
for(var prop in obj){
  var fx = obj[prop];
  if(obj.hasOwnProperty(prop) && (typeof fx == 'function') && /eval\(instance/.test(fx)){
    console.log(prop)
  }
}

I grabbed this from http://stackoverflow.com/questions/2052361/get-externalinterface-definitions-in-javascript to try to "reverse engineer" the methods exposed by a .swf. I had to remove the last && /eval part to get the list.
