有两种方式可以访问对象属性：
</p>
<p>
你可以使用 .property 或 ["property"].
</p>
<p id="demo"></p>
<script>
var person = {
firstName : "John",
lastName : "Doe",
id : 5566
};
document.getElementById("demo").innerHTML =
person.firstName + " " + person.lastName;
</script> </body>
</html>

<body> <p>创建和使用对象方法。</p>
<p>对象方法作为一个函数定义存储在对象属性中。</p>
<p id="demo"></p>
<script>
var person = {
firstName: "John",
lastName : "Doe",
id : 5566,
fullName : function()
{
return this.firstName + " " + this.lastName;
}
};
document.getElementById("demo").innerHTML = person.fullName();
</script> </body>
</html>
