I want to create a function in javascript with a variable amount of arguments. The next example is how I want to call this function:

myFunction(1,2);

myFunction(1,2,3);

myFunction(1,2,3,4);

myFunction(1,2,3,4,5);

myFunction(1,2,3,4,5,6);

Anyone knows how to define this function?

You can access the arguments by their ordinal position without the need to state them in the prototype as follows:

function myFunction() {

  for (var i = 0; i < arguments.length; i++)

    alert(arguments[i]);

}



myFunction(1, 2, three);



>>1

>>2

>>three

Or if you really are passing in a set of semantically related numbers you could use an array;

function myFunction(arr) { ... }

result = myFunction([1,2,3]);
