JavaScript创建对象的几种方式

1：使用new关键字创建；

person=new Object();person.firstname="Bill";person.lastname="Gates";person.age=56;person.eyecolor="blue";

2：使用替代语法（使用对象 literals）；

person={firstname:"John",lastname:"Doe",age:50,eyecolor:"blue"};

3：使用函数来构造对象；

function person(firstname,lastname,age,eyecolor){this.firstname=firstname;this.lastname=lastname;this.age=age;this.eyecolor=eyecolor;}

var myFather=new person("Bill","Gates",56,"blue");var myMother=new person("Steve","Jobs",48,"green");
