Javascript 组多级JSON

不确定问题标题是否是自描述性的，但下面是问题陈述：我想将多级JSON转换为多级分组JSON。我们的想法是使用这个JSON数据来创建accordion。在这方面有没有图书馆可以帮助我

提前谢谢

JSON我有-

如果所有

评估

对象都具有相同的

评估ID

，则可以对以下数据使用：

var result = data.reduce(function(s, d, idx){
    if(idx==0){
      let apps = [];
      apps.push(s.Assessment.Measures.SubMeasures.Apps);
       s.Assessment.Measures.SubMeasures.Apps = apps;
    }else{
  s.Assessment.Measures.SubMeasures.Apps.push(d.Assessment.Measures.SubMeasures.Apps);
    }
    return s;
}, data[0]);

说明：

使用

data[0]

使用

data[0]

数组中的第一项初始化

result

对象，并将其传递给

.reduce（）

调用，并将其

Assessment.Measures.SubMeasures.Apps

转换为

数组

，然后在每次迭代时将所有

Assessment.Measures.SubMeasures.Apps

推送到该数组上

演示：

var数据=[{
“评估”：{
“评估ID”：3，
“评估文本”：“CRM”，
“措施”：{
“测量”：6，
“MeasureText”：“CF”，
“子测量”：{
“亚测量”：12，
“子测量文本”：“TNCF”，
“应用程序”：{
“名称”：“机器人”，
“评级”：0
}
}
}
}
},
{
“评估”：{
“评估ID”：3，
“评估文本”：“CRM”，
“措施”：{
“测量”：6，
“MeasureText”：“CF”，
“子测量”：{
“亚测量”：12，
“子测量文本”：“TNCF”，
“应用程序”：{
“名称”：“CPSM”，
“评级”：0
}
}
}
}
},
{
“评估”：{
“评估ID”：3，
“评估文本”：“CRM”，
“措施”：{
“测量”：6，
“MeasureText”：“CF”，
“子测量”：{
“亚测量”：12，
“子测量文本”：“TNCF”，
“应用程序”：{
“名称”：“DEA”，
“评级”：0
}
}
}
}
}
];
var结果=数据.reduce（函数（s、d、idx）{
如果（idx==0）{
让应用程序=[]；
应用程序推送（s.评估.度量.子度量.应用程序）；
s、 Assessment.Measures.SubMeasures.Apps=应用程序；
}否则{
s、 评估.度量.子度量.应用程序.推送（d.评估.度量.子度量.应用程序）；
}
返回s；
}，数据[0]）；
控制台日志（结果）

您可以将哈希表作为相同

AssessmentId

和

MeasureId

的引用

如果不存在散列，则使用实际数据的副本（原始数据没有变化）构建一个新对象，并将

Apps

值放入数组中。将临时opbejct推送到结果数组，并在哈希表中保留对

Apps

数组的引用

如果找到一个已知的散列，那么只需更新数组

var数据=[{评估：{AssessmentId:3，AssessmentText:“CRM”，度量：{MeasureId:6，MeasureText:“CF”，子度量：{SubMeasureId:12，SubMeasureText:“TNCF”，Apps:{Name:“BOT”，Rating:0}}}}}，{评估：{AssessmentId:3，AssessmentText:“CRM”，度量：{MeasureId:6，MeasureText:“CF”，子度量：{子测量ID:12，子测量文本：“TNCF”，应用程序：{名称：“CPSM”，评级：0}}}}}}，{评估：{评估ID:3，评估文本：“CRM”，度量：{测量ID:6，测量文本：“CF”，子测量：{子测量文本：12，子测量文本：“TNCF”，应用程序：{名称：“DEA”，评级：0}}}}，{评估：{评估：{评估ID:3，评估文本：“CRM”，度量值：{MeasureId:8，MeasureText:“DEV”，子度量值：{SubMeasureId:16，SubMeasureText:“CICD”，应用程序：{Name:“BOT”，评级：0}}}}}}，{Assessment:{AssessmentId:3，AssessmentText:“CRM”，度量值：{MeasureId:8，MeasureText:“DEV”，子度量值：{SubMeasureId:16，SubMeasureText:“CICD”，应用程序：{Name:“CPSM”，评级：0}}}，{评估：{AssessmentId:3，AssessmentText:“CRM”，度量：{MeasureId:8，MeasureText:“DEV”，子度量：{子度量ID:16，子度量文本：“CICD”，应用程序：{Name:“DEA”，评级：0}}]，
hash=Object.create（null），
结果=[]；
data.forEach（函数（o）{
var key=[o.Assessment.AssessmentId，o.Assessment.Measures.MeasureId].join（“|”），
临时雇员
if（散列[键]）{
hash[key].push（o.Assessment.Measures.SubMeasures.Apps）；
返回；
}
hash[key]=[o.Assessment.Measures.SubMeasures.Apps]；
temp=JSON.parse（JSON.stringify（o））；
temp.Assessment.Measures.SubMeasures.Apps=散列[键]；
结果：推送（温度）；
});
console.log（结果）；

。作为控制台包装器{max height:100%！important；top:0；}

您可以轻松地手动迭代JSON，只要键（“Apps”）分组的方式是固定的……应该是

度量值

和

子度量值

数组？@NinaScholz我每个度量值有10个应用程序，我有3组度量值/子度量值，但它们来自服务的方式是我在示例中显示的方式。我得到30组json对象，我想将其分组为3个对象，每个对象包含10个应用程序。这意味着是吗？不是，json对象中唯一的数组将是apps。我更新了一点示例输入/输出。你能基于这一点提出建议吗。你为什么使用

hash=object.create（null）

而不是简单的

hash={}

？@cars10m，如果你有一把像

toString

这样的钥匙，那么它就是

对象的原型，但这里不需要。
