You can do this a number of ways depending on your need.
With an associative array/map object:
var map = {
'somekey' : dcbase.myCustomerButton,
'otherkey' : dcbase.otherTypeOfButton
};
var val = 'somekey';
var lcClass = new (map[val])();
Or you could do it with a call to eval:
var classToCreate = 'dcbase.myCustomerButton';
var lcClass = eval('new ' + classToCreate + '()');
Or you could do it, similar to the first technique, but with a factory
method (probably attached statically to a parent class of all the
objects you might create in this instance).
