原型链继承
window.onload=function test() {
function SuperType () {
this.property = true;
}
SuperType.prototype.getSuperValue = function () {
return this.property;
};
function SubType () {
this.subproperty = false;
}
SubType.prototype = new SuperType();
SubType.prototype.getSubValue = function () {
return this.subproperty;
};
var instance = new SubType();
alert(instance.getSuperValue());
组合继承
function SuperType (name) {
this.name = name;
this.colors = ["blue","green","red"];
}
SuperType.prototype.sayName = function () {
alert(this.name);
};
function SubType (name,age) {
//继承属性
SuperType.call(this,name);
this.age = age;
}
//继承方法
SubType.prototype = new SuperType();
SubType.prototype.constructor = SubType;
SubType.prototype.sayAge = function () {
alert(this.age);
};
var instance1 = new SubType("liqiang",29);
instance1.colors.push("black");
alert(instance1.colors);
instance1.sayName();
instance1.sayAge();
var instance2 = new SubType("mingming",30);
alert(instance2.colors);
instance2.sayAge();
instance2.sayName();
寄生式继承
function createAnother (original) {
var clone = Object.create(original);
clone.sayHi = function () {
alert("Hi");
};
return clone;
}
var person = {
name: "liqiang",
age: 23
};
var anotherPerson = createAnother(person);
anotherPerson.sayHi();
