I think your issue is that JavaScript does not support function
overloading.
What your code is equivalent to is:
a = function(p1) {...};
a = function(p1, p2) {...};
The second definition replaces the value of a.
You may want to use the arguments array instead:
function a(p1)
{
if (arguments.length == 1)
globalVariable = '1 param called';
else if (arguments.length == 2)
globalVariable = '2 param called';
//or if you want to be fancy:
globalVariable = arguments.length + ' param called';
}
