Jquery 对json的增删改: 查询（遍历）

jquery 对得到的json 进行增删改 操作

var ojson={'a':[{'id':'5'},{'id':'6'}],'b':[{'id':'8'},{'id':'9'}]}; 
 

var t=[{'a':1},{'a':2}];

t.push({'a':3});//增
t[0].a=11;//改
t.remove(0);//删

查询：遍历

举例如下：

var people=

{"userDetails":

[

 {"sm_uid":"226","sm_user":"librashengsh","sm_uname":"ss","sm_tea_pic":"TeacBbsPic/20100422094813.jpg"},

 {"sm_uid":"231","sm_user":"ssssss","sm_uname":"ss","sm_tea_pic":"TeacBbsPic/20100505135408.jpg"},

 {"sm_uid":"295","sm_user":"yusuke","sm_uname":"ykl","sm_tea_pic":"images/upic.gif"},

 {"sm_uid":"227","sm_user":"abcdefg","sm_uname":"abc","sm_tea_pic":"TeacBbsPic/20100422154044.jpg"}

 ]};

//下面是普通搜索

for (var i in people['userDetails']) {

   if (people['userDetails'][i].sm_uid=="226") {

        alert(people['userDetails'][i].sm_user);//获得该id下的名字

   }

}

//下面是模糊搜索

for (var i in people['userDetails']) {

   if (people['userDetails'][i].sm_uid.indexOf('2') != -1) {

        alert(people['userDetails'][i].sm_uid);

   }

}
