motools json操作

一、JSON格式：
{
    "metadata": [
        {"id": "ACTID",  "name": "日志ID", "isQuery": "1", "isShow": "0"
        },
        { "id": "LOGSOURCE",  "name": "日志来源", "isQuery": "0", "isShow": "1"
        },
        {"id": "LOGLEVEL",  "name": "日志级别", "isQuery": "0", "isShow": "1"
        },
        { "id": "LOGPRIORITY", "name": "日志优先级","isQuery": "0", "isShow": "1"
        },
        {"id": "USERID",  "name": "用户ID", "isQuery": "0","isShow": "1"
        },
        {"id": "USERNAME", "name": "用户", "isQuery": "0", "isShow": "1"
        },
        { "id": "USERAC",  "name": "源账号", "isQuery": "0", "isShow": "1"
        },
        {"id": "USERIP","name": "源IP","isQuery": "0", "isShow": "1"
        },
        {"id": "GROUPID", "name": "部门ID", "isQuery": "0", "isShow": "0"
        },
        {"id": "GROUPNAME",  "name": "部门","isQuery": "0", "isShow": "1"
        },
        {"id": "OPERTIME",  "name": "操作时间","isQuery": "0",  "isShow": "1"
        },
        {"id": "OPERTIMEYEAR", "name": "年",  "isQuery": "0", "isShow": "1"
        }
    ],
    "rows": [
        {
            "OPERTIMEYEAR": "2016",
            "USERAC": "lujunqi",
            "GROUPID": "",
            "OPERSTATE": "1",
            "RESOURCETYPE": "Res-Host",
            "USERIP": "132.230.108.109",
            "GROUPNAME": "",
            "OPERTIME": "2016-06-01 00:00:04.000"
        },
        {
            "OPERTIMEYEAR": "2016",
            "USERAC": "seven",
            "GROUPID": "368009",
            "OPERSTATE": "1",
            "RESOURCETYPE": "Res-Host",
            "USERIP": "192.168.2.123",
            "GROUPNAME": "江西省通信产业服务有限公司（实业公司）",
            "OPERTIME": "2016-08-31 13:14:21.000"
        }
    ]
}

二、获取json对象
var jsonResult = JSON.decode('(' + json内容+ ')');

三、解析内容
var metadates = jsonResult.metadata;
for (var i = 0; i < metadates.length; i++) {
     fname = metadates[i].name;
     isShow = metadates[i].isShow;
}

var rows = jsonResult.rows;
for (var i = 0; i < rows.length; i++) {
row = rows[i];
for (var j = 0; j < metadates .length; j++) {
//获取rows字段值
row[metadata[j].id];
}
}
