Question

I have an array of functions and also I am using a dynatree plugin inside it.

Example:

fn1: function(){ 
   .....
}),
fn2: function(){ 
   .....
}),
fn3: { param1: xValue, param2: yValue }

Now I would like to add a function in fn3 like,

fn3: fn3a

//In fn3a
function fn3a(){
    //Based on condition add values.
    if...
        param1: xValue, param2: yValue
    else...
       param1: xValue, param2: zValue
}

How can I define those params in {…} in function.

Please suggest.
Thanks in advance.

Don’t really know if this is what you’re looking for, but maybe it’s a start:

var funcs = {
  /* ...  others functions ... */
  fn3: { param1: 2, param2: 3 }
};


funcs.fn3 = (function (/*the old object*/ oldValue){
  /*
    ... private variable scope here, which will be accessible by the returned
    function only! ...
  */

  /* do stuff with the old values and store the values in private scope */
  var
    param1 = oldValue.param1 * oldValue.param1,
    param2 = oldValue.param2 * oldValue.param2;

  /* return a new function */
  return function () {
    /* the new return value */
    return param1 + '/' + param2;
  };
}(/*pass the old object*/ funcs.fn3));


// debug output:
console.log(funcs.fn3()); // => 4/9
