Objective Programming in javascript (class commitment) (Tip 9)

// Human base type
Var Person = new (function ()
{
Var sex;
Var name;
This. getSex = function ()
{
Return sex;
}
This. setSex = function (value)
{
Sex = value;
}
}
);
// Students must accept "persons"
Var Student = function (parent)
{
This. _ class _ = parent;
Var workid;
This. _ class _. getWorkid = function ()
{
Return workid;
}
This. _ class _. setWorkid = function (value)
{
Workid = value;
}
Return this. _ class _;
}

Example: var st = new Student (Person );
St. setWorkid ("9527 ");
St. setSex ("man ");
Alert (st. getSex ());
Alert (st. getWorkid ());
