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);
