json取值 嵌套

直接看代码：

var data = {
    "base":{
        "accountname":"0416",
        "account":"0416",
        "protocolno":"JG202205300002",
        "paynode":{"name":{"name3":"value3","name4":"value4"},"name2":"value2"},
        "money":0,
        "subaccid":385,
        "approid":455,
        "remark":""
    },
    "items":[

    ]
}
console.log(data["base"].paynode.name.name3);
> value3
