java - 在 Jquery 中基于 KeyPair 循环 json 数据

Question

大家好，下面是我从服务器收到的响应。我尝试根据按键循环它，不幸的是我没有成功。

{"metricsLevelList": [{
"levelName": "Account1Name",
"levelId": 1,
"metrics":    [
        {
     "value": "80",
     "greenZoneStart": "90",
     "greenZoneEnd": "100",
     "yellowZoneStart": "60",
     "yellowZoneEnd": "90",
     "redZoneStart": "0",
     "redZoneEnd": "60",
     "metricsType": "Dial",
     "metricsName": "FTR Deliverables"
  },
        {
     "value": "0",
     "greenZoneStart": "90",
     "greenZoneEnd": "100",
     "yellowZoneStart": "60",
     "yellowZoneEnd": "90",
     "redZoneStart": "0",
     "redZoneEnd": "60",
     "metricsType": "Dial",
     "metricsName": "OTD Deliverables"
  },
        {
     "value": "0",
     "greenZoneStart": "0",
     "greenZoneEnd": "5",
     "yellowZoneStart": "5",
     "yellowZoneEnd": "15",
     "redZoneStart": "15",
     "redZoneEnd": "100",
     "metricsType": "Dial",
     "metricsName": "% Defect Rejection"
  },
        {
     "value": null,
     "greenZoneStart": null,
     "greenZoneEnd": null,
     "yellowZoneStart": null,
     "yellowZoneEnd": null,
     "redZoneStart": null,
     "redZoneEnd": null,
     "metricsType": null,
     "metricsName": null
  },
        {
     "value": "0",
     "greenZoneStart": "90",
     "greenZoneEnd": "100",
     "yellowZoneStart": "70",
     "yellowZoneEnd": "90",
     "redZoneStart": "0",
     "redZoneEnd": "70",
     "metricsType": "Dial",
     "metricsName": "CSAT (% VoC)"
  }
]
}]}

在这里，我必须在另一个指标循环(具有指标内容)内循环指标级别列表(其中我将有不同的级别名称)。请有人帮我解决这个问题。

您可以使用以下循环来迭代嵌套对象(假设您的 json 存储在名为 jsonDemo 的变量中):

function loop(obj) {
    $.each(obj, function(key, val) {
        if(val && typeof val === "object") { // object, call recursively
            console.log(" "); 
            loop(val);
        } else {
            console.log(key + "-->" + obj[key]); 
        }
    });
}

loop(jsonDemo);

参见 fiddle :“http://jsfiddle.net/pgo637dj/”

说明:这将迭代对象的所有键并检查每个键是否是一个对象，如果是，则递归调用它，否则将显示它。
