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");
