Dynamically call javascript functions

austinf · May 13th, 2006, 07:18 AM

hi i have 4 functions named

func1(), func2(), func3(), func4()

The problem is it has to be called based on the number.

i tried using eval() but it is not a good way so i would like to know how to dynamically call any one of the methods if the number is passed

thanks for the help

Code:

function callFunctionByIndex(index)
{
  var functions = [func0, func1, func2, func3, func4];
  return functions[index]();
}

If you don't have or want a func0 then use [--index] in the function body.
