Json对象在JS里面的处理

1、遍历Json对象

myJson = {"name":"nikita", "password":"1111"};

for(var p in myJson){//遍历json对象的每个key/value对,p为key

   alert(p + " " + myJson[p]);

}

2、遍历Json对象数组

packJson = [

{"name":"nikita", "password":"1111"},

{"name":"tony", "password":"2222"}

];

for(var p in packJson){//遍历json数组时，这么写p为索引，0,1

   alert(packJson[p].name + " " + packJson[p].password);

}
