使js具有继承能力的方法 [英] a method to make js have the ability to inherit
问题描述
我找到一种方法让javescript更像c ++或pyhon
有示例代码：
function Father（self）//每个构造函数都可能有自我
参数
{
self = self？self：this; //每个班级都有这个陈述
self.hello = function（）
{
alert（" father" + self.name）;
}
self.name =" baibai";
}
function Child（self）//每个构造函数都可能有self争论
{
self = self？self：this; //每个班级都有这个陈述
//从faher继承
父亲（个体经营）;
self.hello = function（）
{
alert（" child" + self.name）;
}
}
a =新父亲（）;
a.hello（）;
b = new Child（）;
b.hello（）;
Hi,I find a way to make javescript more like c++ or pyhon
There is the sample code:
function Father(self) //every contructor may have "self"
argument
{
self=self?self:this; //every class may have this statement
self.hello = function()
{
alert("father"+self.name);
}
self.name = "baibai";
}
function Child(self) //every contructor may have "self" argument
{
self=self?self:this; //every class may have this statement
//inherit from faher
Father(self);
self.hello = function()
{
alert("child"+self.name);
}
}
a = new Father();
a.hello();
b = new Child();
b.hello();

但是你使用一小部分代码并使用
javascript继承所取得的成就。 >
大大减少了复杂性？例如，如下： -
函数父亲（）{
}
Father.prototype = {
你好：function（）{
alert（this.type + this.name）;
};
type："父亲;
名字：父亲
};
函数Child（）{
}
Child.prototype = new父（）：
Child.prototype.type =''child'';
a = new Father（）;
a.hello（）;
b = new Child（）;
b.hello（）;

But have you achieved anything more than can be done with normal
javascript inheritance, using a fraction of the code and with
considerably less added complexity? For example, as:-
function Father(){
}
Father.prototype = {
hello:function(){
alert(this.type+this.name);
};
type:"father";
name:"father"
};
function Child(){
}
Child.prototype = new Father():
Child.prototype.type = ''child'';
a = new Father();
a.hello();
b = new Child();
b.hello();

type:"father";

对象文字中的名称值对应以逗号分隔，而不是以
分号分隔。 IE： -
Father.prototype = {
hello：function（）{
alert（this.type + this。姓名）;
}，
类型：父亲，
姓名：" father"

The name value pairs in the object literal should be comma separated not
semicolon separated. I.E:-
Father.prototype = {
hello:function(){
alert(this.type+this.name);
},
type:"father",
name:"father"
};
