Convert small letter to capital letter

[User_267]

There are two fields last name and name. So when I enter something in last name field. The first letter it needs to be populate in name field.  

I used below code:

Using onchange

Var name1= g_form.getValue('lastname');

Var f1= name1.charAt(0);

g_form.setValue("name", f1);

So this code is working fine for autopopulate.

For ex: lastname- Testing

Name-t (small letter)the first letter is in small letter I need capital letter how to add that in this code.
