Is there a way to find out the call

Answer 1

Try the following code:

function getStackTrace(){
  var f = arguments.callee;
  var ret = [];
  var item = {};
  var iter = 0;

  while ( f = f.caller ){
      // Initialize
    item = {
      name: f.name || null,
      args: [], // Empty array = no arguments passed
      callback: f
    };

      // Function arguments
    if ( f.arguments ){
      for ( iter = 0; iter

Worked for me in Firefox-21 and Chromium-25.
