js创建类的方式有几种,大致如下:
1,构造函数方式:
function Car(parameters) {
this.name = "objectboy";
} var cat1 = new Car();
console.log(cat1.name);
2,Object.create()
var Cat = {
name: "大毛",
makeSound: function(){ alert("喵喵喵"); }
}; var cat1 = Object.create(Cat);
alert(cat1.name); // 大毛
cat1.makeSound(); // 喵喵喵
感觉有点复杂
3,最简单的方式
var Car = {
CreateNew: function() {
var cat = {};
cat.name = "objectboy";
cat.age = 26;
cat.makeJS = function() {
alert("我是objectboy");
};
return cat;
}
};
var cat1 = Car.CreateNew();
console.log(cat1.name);
cat1.makeJS();
个人认为第三种从理解方面来说是最好的,
继承特性:
var sl = {
CreateNew: function () {
var cat = {};
cat.sleep = function() {
alert("objectboy在睡觉");
};
return cat;
}
}; //先定义一个需要继承的类
var Car = {
CreateNew: function() {
var cat = sl.CreateNew();
cat.name = "objectboy";
cat.age = 26;
cat.makeJS = function() {
alert("我是objectboy");
};
return cat;
}
};
var cat1 = Car.CreateNew();
console.log(cat1.name);
cat1.makeJS();
cat1.sleep(); //调用继承方法
