JS中获取函数调用链所有参数的方法

function getCallerArgument(){
  var result = [];
  var slice = Array.prototype.slice;
  var caller = arguments.callee.caller;

  while(caller){
    result = result.concat(slice.call(caller.arguments, 0));
    caller = caller.arguments.callee.caller;
  }
  return result;
};

var a = function(){b("a1","a2")}, 
b = function(){b("b1","b2")},
c= function(){return getCallerArgument()};
c("c1");
