JavaScript get parent function arguments

Question

I have a function like:

define(['module', 'controller'], function(module, controller){
     (new module).build();
});

inside module.build I want to get the arguments automatically of the parent like:

module = function(){
    this.build = function(args){
        // make args the arguments from caller ( define ) fn above
    };
};

I know I could do something like:

module.build.apply(this, arguments);

but I was wondering if there was a better way. Any thoughts?

Answer 1

There is a way to do this, illustrated in this example (http://jsfiddle.net/zqwhmo7j/):

function one(){
  two()
}
function two(){
  console.log(two.caller.arguments)
}
one('dude')

It is non-standard however and may not work in all browsers:

You would have to change your function like so:

module = function(){
  this.build = function build(args){
      // make args the arguments from caller ( define ) fn above
    console.log(build.caller.arguments)
  };
};
