How to access this JSON value?

我从列表的Spring mvc控制器生成了以下json字符串。如何在jquery中访问holidayName属性。

[{"holidayId":1,"holidayName":"Raksha Bandhan",
  "holidayStartDate":"Aug 2, 2012 12:00:00 AM",
  "holidayEndDate":"Aug 2, 2012 12:00:00 AM"},
 {"holidayId":2,"holidayName":"Independence day",
  "holidayStartDate":"Aug 15, 2012 12:00:00 AM",
  "holidayEndDate":"Aug 15, 2012 12:00:00 AM"}]

Answer 1

 var data=[
           {"holidayId":1,"holidayName":"Raksha Bandhan","holidayStartDate":"Aug 2, 2012 12:00:00 AM","holidayEndDate":"Aug 2, 2012 12:00:00 AM"},
           {"holidayId":2,"holidayName":"Independence day","holidayStartDate":"Aug 15, 2012 12:00:00 AM","holidayEndDate":"Aug 15, 2012 12:00:00 AM"}
         ]

   $.each(data,function(index,item){       
        alert(item.holidayName)      
   });

我不熟悉Spring MVC，但是你应该注意观察你正在使用的起始“json字符串”是 字符串 还是对象。

如果是字符串，则需要首先使用$ .parseJSON作为@Felix提及。

如果它已经是一个对象，那么你可以像@Shyju那样直接访问它，或者像没有每个循环那样访问它：

var input = 
    [
        {
            "holidayId": 1,
            "holidayName": "Raksha Bandhan",
            "holidayStartDate": "Aug 2, 2012 12:00:00 AM",
            "holidayEndDate": "Aug 2, 2012 12:00:00 AM"
        },
        {
            "holidayId": 2,
            "holidayName": "Independence day",
            "holidayStartDate": "Aug 15, 2012 12:00:00 AM",
            "holidayEndDate": "Aug 15, 2012 12:00:00 AM"
        }
    ];

console.log(input[0]['holidayName']); //'Raksha Bandhan'
console.log(input[1]['holidayName']); //'Independence Day'
