标签： javascript jquery json

不确定问题标题是否是自描述的，但这里是问题陈述：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数据来创建手风琴。有没有可以帮助我的图书馆？

提前致谢。

JSON我有 -

您可以将哈希表作为对同一AssessmentId和MeasureId的引用。

如果不存在散列，则使用实际副本（没有原始数据的变异）构建新对象，并将Apps值转换为数组。将临时opbejct推送到结果数组，并保持对哈希表中Apps数组的引用。

如果找到已知的哈希，则只需更新数组。

＆＃13;
＆＃13; 
var data = [{ Assessment: { AssessmentId: 3, AssessmentText: "CRM", Measures: { MeasureId: 6, MeasureText: "CF", SubMeasures: { SubMeasureId: 12, SubMeasureText: "TNCF", Apps: { Name: "BOT", Rating: 0 } } } } }, { Assessment: { AssessmentId: 3, AssessmentText: "CRM", Measures: { MeasureId: 6, MeasureText: "CF", SubMeasures: { SubMeasureId: 12, SubMeasureText: "TNCF", Apps: { Name: "CPSM", Rating: 0 } } } } }, { Assessment: { AssessmentId: 3, AssessmentText: "CRM", Measures: { MeasureId: 6, MeasureText: "CF", SubMeasures: { SubMeasureId: 12, SubMeasureText: "TNCF", Apps: { Name: "DEA", Rating: 0 } } } } }, { Assessment: { AssessmentId: 3, AssessmentText: "CRM", Measures: { MeasureId: 8, MeasureText: "DEV", SubMeasures: { SubMeasureId: 16, SubMeasureText: "CICD", Apps: { Name: "BOT", Rating: 0 } } } } }, { Assessment: { AssessmentId: 3, AssessmentText: "CRM", Measures: { MeasureId: 8, MeasureText: "DEV", SubMeasures: { SubMeasureId: 16, SubMeasureText: "CICD", Apps: { Name: "CPSM", Rating: 0 } } } } }, { Assessment: { AssessmentId: 3, AssessmentText: "CRM", Measures: { MeasureId: 8, MeasureText: "DEV", SubMeasures: { SubMeasureId: 16, SubMeasureText: "CICD", Apps: { Name: "DEA", Rating: 0 } } } } }],
    hash = Object.create(null),
    result = [];

data.forEach(function (o) {
    var key = [o.Assessment.AssessmentId, o.Assessment.Measures.MeasureId].join('|'),
        temp;

    if (hash[key]) {
        hash[key].push(o.Assessment.Measures.SubMeasures.Apps);
        return;
    }
    hash[key] = [o.Assessment.Measures.SubMeasures.Apps];
    temp = JSON.parse(JSON.stringify(o));
    temp.Assessment.Measures.SubMeasures.Apps = hash[key];
    result.push(temp);
});

console.log(result);

答案 1 :(得分：0)

如果所有Assessment个对象具有相同的AssessmentId，您可以对这些数据使用 .reduce() method ：

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]);

<强>解释

使用result数组中的第一项初始化data对象，使用data[0]并通过.reduce()调用传递，并将其Assessment.Measures.SubMeasures.Apps转换为array然后在每次迭代时推送Assessment.Measures.SubMeasures.Apps上的所有var data = [{ "Assessment": { "AssessmentId": 3, "AssessmentText": "CRM", "Measures": { "MeasureId": 6, "MeasureText": "CF", "SubMeasures": { "SubMeasureId": 12, "SubMeasureText": "TNCF", "Apps": { "Name": "BOT", "Rating": 0 } } } } }, { "Assessment": { "AssessmentId": 3, "AssessmentText": "CRM", "Measures": { "MeasureId": 6, "MeasureText": "CF", "SubMeasures": { "SubMeasureId": 12, "SubMeasureText": "TNCF", "Apps": { "Name": "CPSM", "Rating": 0 } } } } }, { "Assessment": { "AssessmentId": 3, "AssessmentText": "CRM", "Measures": { "MeasureId": 6, "MeasureText": "CF", "SubMeasures": { "SubMeasureId": 12, "SubMeasureText": "TNCF", "Apps": { "Name": "DEA", "Rating": 0 } } } } } ]; 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]); console.log(result);。

编辑：

好吧，如果你有多个array个对象，并且想要在var result = {}; data.forEach(function(d, idx) { if (idx == 0) { let s = d; let subMeasures = []; let apps = []; apps.push(d.Assessment.Measures.SubMeasures.Apps); s.Assessment.Measures.SubMeasures.Apps = apps; subMeasures.push(d.Assessment.Measures.SubMeasures); s.Assessment.Measures.SubMeasures = subMeasures; result = Object.assign({}, s); } else { let found = elemExists(result.Assessment.Measures.SubMeasures, "SubMeasureId", d.Assessment.Measures.SubMeasures.SubMeasureId); if (found >= 0) { result.Assessment.Measures.SubMeasures[found].Apps.push(d.Assessment.Measures.SubMeasures.Apps); } else { result.Assessment.Measures.SubMeasures.push(d.Assessment.Measures.SubMeasures); } } }); 中对它们进行分组，那么你可以试试这个代码：

elemExists(array, property, val)

其中element是一个util函数，用于检查array中是否存在property，使用特定的objects来比较迭代的index并返回{ {1}}中的object {1}}。{/}
