关于第三方接口返回JSON数据的解析

[womenyiq]

我调用第三方接口时，返回JSON数据当中含有数组。我如何在JSP页面上取得相关数据。或者是全部遍历出来。

例如：
"error_code":0,
"reason":"成功",
"result":[
{
"provinceId":"v2129",
"provinceName":"甘肃",
"cityList":[
{
"cityId":"v77068",
"cityName":"金昌",
"rechargeTypeList":[
{
"payProjectId":"c2680",
"payProjectName":"电费",
"payUnitId":"v8132216",
"payUnitName":"金昌供电公司",
"payModeList":[
{
"payModeId":"v2620",
"payModeName":"户号",
"productId":null,
"productName":null,
"inprice":null
}
]
}
]
},...........
}
]
},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...}
]
},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...},
Object{...}
]
}
取得相关的数据。求师傅帮我指点一下

“遍历”这个动词不适用于json对象，不知道怎么遍历

[dengchenlu]

知道哪个元素是集合的话，就可以通过循环遍历啊。 类似 var arr2 = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] $.each(arr2, function(i, item){ alert(item[0]); });
