List of global user defined functions in JavaScript?

Question

Is it possible to get a list of the user defined functions in JavaScript?

I\'m currently using this, but it returns functions which aren\'t user defined:

<         


        

Answer 1

Using Internet Explorer:

var objs = [];
var thing = {
  makeGreeting: function(text) {
    return 'Hello ' + text + '!';
  }
}

for (var obj in window){window.hasOwnProperty(obj) && typeof window[obj] === 'function')objs.push(obj)};

Fails to report 'thing'.
