Javascript function parameters issue

Question

I am trying to pass parameters to a function. I have:

function test(var1, var2, var3, var4, callBack, Scroll, punc, var5){
    codes....
}

When I call the function:

test('a','b','c','d','e');

I want 'e' to be var 5 instead of callback parameter. Is there anyway to do it?

If you call test() with those arguments, what do you want the values stored in callBack, Scroll, and punc to be? They can't come from nowhere. — cdhowie

What are you looking to change here? Are you looking to modify the function test so that you can call it in the way you describe? Or are you looking to modify the call to test so that it matches what the function expects? — ruakh

It really depends on your function but supposing it accepts to lack a callback you could do this :

test('a','b','c','d', undefined, undefined, undefined, 'e');

If it really needs a callback, do this :

test('a','b','c','d',function(){}, undefined, undefined, 'e');
