Hi everybody,

I want to create JavaScript Objects according to the name passed as
String-parameter. It is like reflection in java.

example:

function getObject(className)
{
  // works, but not the way I want to do it
  if (className == "MyClass")
  {
    return new MyClass();
  } 
  else if (className == "AClass") 
  {
    return new AClass();
  } 
  else 
  {
    return null;
  }

  // pseudo code - as it should work
  try
  {
     var aClass = Class.forName(className);
     var object = aClass.newInstance();
     return object;
  }
  catch (error)
  {
    // exception handling
  }
}

function MyClass()
{
  this.color = "red"
}

function AClass()
{
  this.number = 1;
}

Is there a way in JavaScript to create objects in this way?

thanks in advance 

Mike
