Search Within Multilevel Json Tree Using Multiple Keys

I have a json tree with following structure { 'treeId': 'avhsgdkendkfhjsdoiendsj', 'groupResponse': { 'description': null, 'id': 'avhsgdkendkfhjsdoiendsj',

Solution 1:

The following might help,

vardata = {
  'treeId': 'avhsgdkendkfhjsdoiendsj',
  'groupResponse': {
    'description': null,
    'id': 'avhsgdkendkfhjsdoiendsj',
    'mAttr': null,
    'mAttrVal': null
  },
  'childResponse': [
    {
      'treeId': '6p263uh38xvnchmsrw2jn48ut',
      'childResponse': [
      ],
      'groupResponse': {
        'description': null,
        'id ': '6p263uh38xvnchmsrw2jn48ut',
        'mAttr': 'xxx',
        'mAttrVal': '222'
      }
    },
    {
      'treeId': '2fywxwi93lg7fqggdqqpqxvpg',
      'childResponse': [
      ],
      'groupResponse': {
        'description ': null,
        'id': '2fywxwi93lg7fqggdqqpqxvpg',
        'mAttr': 'xxx',
        'mAttrVal': '111'
      }
    }
  ]
};

var search = function(data, qObj){
  var i, k, matched = true, set = [];
  for (k in qObj) {
    if(!qObj.hasOwnProperty(k))
      continue;
    if(!data.groupResponse.hasOwnProperty(k) || data.groupResponse[k] != qObj[k]){
      matched = false;
      break;
    }
  }
  if(matched){
    set.push(data.groupResponse);
  }
  for(i = 0; i < data.childResponse.length; i++){
    s = search(data.childResponse[i], qObj);
    Array.prototype.push.apply(set, s);
  }
  returnset;
}

console.log(search(data, { "mAttr": "xxx", "mAttrVal": "222"}));

Output:

[{"description":null,"id ":"6p263uh38xvnchmsrw2jn48ut","mAttr":"xxx","mAttrVal":"222"}]

hope this helps

Solution 2:

I didn't test it, but I think it should work

Object.prototype.findKey = function(keyObj) {
    var p,key,tRet=[],add=true;
    for (p inthis) {
        if (this[p] instanceof Object) {
            if (this.hasOwnProperty(p)) {
                tRet.concat(this[p].findKey(keyObj));
            }
        }
    }
    for(key in keyObj){
        if(!this.hasOwnProperty(key)||!this[key]===keyObj[key])
            add=false;
    }
    if(add)
        tRet.push(this);
    return tRet;
};

Tell me if I'm wrong ;)
