Question

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?

Answer 1

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]);
