javascript 中面向对象編程 （类的继承)
// 人的基類
var Person=new ( function()
{
var sex;
var name;
this.getSex=function()
{
return sex;
}
this.setSex=function(value)
{
sex=value;
}
}
);
//學生類，需要繼承 “人”
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_;
}
示例：
var Person=new ( function(){ var sex; var name; this.getSex=function() { return sex; } this.setSex=function(value) { sex=value; }});//學生類，需要繼承 “人”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_;}示例： var st=new Student(Person);
st.setWorkid("9527");
st.setSex("man");
alert(st.getSex());
alert(st.getWorkid());
st.setWorkid("9527");
st.setSex("man");
alert(st.getSex());
alert(st.getWorkid());
