JSON定义一维和二维数组格式

JSON定义一维数组：

示例完整代码:

<script>  
    var UserList = [{  
        "UserID": 11,  
        "Name": {  
            "FirstName": "Truly",  
            "LastName": "Zhu"  
        },  
        "Email": "zhuleipro◎hotmail.com"  
    },  
    {  
        "UserID": 12,  
        "Name": {  
            "FirstName": "Scott",  
            "LastName": "Gu"  
        },  
        "Email": "xxx2◎xxx2.com"  
    }];  
    alert(UserList[0].Name.FirstName);  
</script>

事实上除了使用"."引用属性外，我们还可以使用下面语句：

alert(UserList[0]["Name"]["FirstName"]); 或者 alert(UserList[0].Name["FirstName"]);

JSON定义二维数组：

示例完整代码:

var UserList = {
    "rec": [{
        "recs": [{
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        },
        {
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        }]
    },
    {
        "recs": [{
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        },
        {
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        }]
    }],
    "rec": [{
        "recs": [{
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        },
        {
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        }]
    },
    {
        "recs": [{
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        },
        {
            "temLink": "132",
            "imageLink": "",
            "itemPrice": "",
            "itemLink": "",
            "itemName": ""
        }]
    }]

};
alert(UserList.rec[0].recs[0].temLink);
