js下的一种面向对象方法

//构造函数
var MClass = function(value1, value2) {
    this.member = "hi";
    //定义成员属性
    Object.defineProperty(this, ‘member1‘, {
        value: value1
    });
    Object.defineProperty(this, ‘member2‘, {
        value: value2
    });
}

MClass.prototype.member0 = "bao";

//原型方法
MClass.prototype.sayHello = function() {
    console.log(this.member + " " + this.member0);
    console.log(‘hello  ‘ + this.member1 + ‘  And  ‘ + this.member2);
    return this;
}

//静态方法（类方法）
MClass.staticSayHello = function() {
    console.log(‘hello  ‘ + this.member0 + " " + this.member);
    return;
}


var entity = new MClass(‘fredric‘, ‘sinny‘);
MClass.staticSayHello();
entity.sayHello().sayHello();

hello  undefined undefined
hi bao
hello  fredric  And  sinny
hi bao
hello  fredric  And  sinny
