  I would like to get the name of the function that called the function.

  example.

  // the popup will show the source of the function that called the function popup
  
  function popup(str){
  
  calledby = "\r\n" + popup.caller;
  
  alert(calledby);
  }
  
  
  function cheese(){
  
  popup('Hello World!');
  
  }
  
  function onion(){
  popup('Hello World!');
  
  
  }
  
  onion(); // when onion() is called, the output is an alert box with

  function onion(){
  popup('Hello World!');
  }
  
  
  
  

  With the method below

  //with this method, no function name is vivible!
  popup =
  {
  
   msg:function(str){calledby = "\r\n" + this.msg.caller; alert(calledby);},
  
   cheese:function(){
   this.msg('Hello World!'
  );
  
   },
  
   onion:function(){
  
   this.msg('Hello World!');
  
   }
  }
  
  
  popup.onion(); // when called, the output doesn't show the function name or caller

  However, the following is the result of the above method

  function (){
  this.msg('Hello World!');
  }
  
  
  
  

  what I was expecting was...

  function popup.msg(){
  popup.msg('Hello World!');
  }
  
  
  

  or similar but it clearly isnt.
  All I need is the name of the function that made the call, eg, popup.onion(), I have used toSource, toString, valueOf methods and they either return the body of the source, the [object Object] or undefined.
  

  Can anyone help? or know what I need to do to get the full name of the object and function through the second method, popup.onion() ???
