JavaScript创建对象的几种方式

/**
 *创建对象方式一，直接通过大括号创建
 */
var Student1 = {};
Student1.name ="张三";
Student1.age =18;
Student1.setName =function (name){
	this.name = name;
};
Student1.getName =function(){
	return this.name;
}
console.log(Student1);
//结果：{ name: '张三', age: 18, setName: [Function], getName: [Function] }
Student1.setName("zhangsan");
console.log(Student1.getName());
//结果：zhangsan

 *创建对象方式二：大括号创建并设置属性

	setName : function(name){

};

//结果：{ name: '张三', age: 18, setName: [Function], getName: [Function] }
Student2.setName("zhangsan");
