जावास्क्रिप्ट नेस्टेड गुणों के साथ वस्तु विलय

Question

नीचे दिए गए उदाहरण पर एक नज़र लेते हैं:

var ref = { 
    "fullName": { 
     "rules": { 
      "type": "string", 
      "minLength": 4, 
      "maxLength": 64 
     }, 
     "description": "Full name of a user." 
    } 
}; 

var user = { 
    "fullName": { 
     "rules": { 
      "required": true, 
      "maxLength": 128 
     }, 
     "message": "You have submitted a wrong full name." 
    } 
}; 

अब क्या मैं चाहता हूँ यह है:

1. मर्ज वस्तुओं & गुण।
2. दूसरी वस्तु के गुणों रखें वे पहले से ही स्थापित कर रहे हैं IF (maxLength)

नीचे परिणाम है कि मैं उम्मीद:

var res = { 
    "fullName": { 
     "rules": { 
      "required": true, 
      "maxLength": 128 
      "type": "string", 
      "minLength": 4 
     }, 
     "description": "Full name of a user.", 
     "message": "You have submitted a wrong full name." 
    } 
}; 

मैं क्या कोशिश की है:

function mergeNestedObjects(firstObject, secondObject) { 
    var finalObject = {}; 

    for (var propertyKey in firstObject) { 
     var propertyValue = firstObject[propertyKey]; 

     if (typeof(propertyValue) === "object") { 
      finalObject[propertyKey] = mergeNestedObjects(firstObject[propertyKey], secondObject[propertyKey]); 
     } else if (secondObject[propertyKey] === undefined) { 
      finalObject[propertyKey] = firstObject[propertyKey]; 
     } else { 
      finalObject[propertyKey] = secondObject[propertyKey]; 
     } 
    } 

    return finalObject; 
} 

उपरोक्त कार्य विलीन हो जाता है लेकिन किसी भी तरह से गुणों को घोंसला नहीं करता है।

अद्यतन & उत्तर यह काम कर रहा है, मैं भी दूसरी वस्तु के माध्यम से itterate, कैसे गूंगा भूल गया। धन्यवाद

function mergeProperties(propertyKey, firstObject, secondObject) { 
    var propertyValue = firstObject[propertyKey]; 

    if (typeof(propertyValue) === "object") { 
     return mergeNestedObjects(firstObject[propertyKey], secondObject[propertyKey]); 
    } else if (secondObject[propertyKey] === undefined) { 
     return firstObject[propertyKey]; 
    } 

    return secondObject[propertyKey]; 
} 

function mergeNestedObjects(firstObject, secondObject) { 
    var finalObject = {}; 

    // Merge first object and its properties. 
    for (var propertyKey in firstObject) { 
     finalObject[propertyKey] = mergeProperties(propertyKey, firstObject, secondObject); 
    } 

    // Merge second object and its properties. 
    for (var propertyKey in secondObject) { 
     finalObject[propertyKey] = mergeProperties(propertyKey, secondObject, firstObject); 
    } 

    return finalObject; 
}

function mergeProperties(propertyKey, firstObject, secondObject) { 
    var propertyValue = firstObject[propertyKey]; 

    if (typeof(propertyValue) === "object") { 
     return mergeNestedObjects(firstObject[propertyKey], secondObject[propertyKey]); 
    } else if (secondObject[propertyKey] === undefined) { 
     return firstObject[propertyKey]; 
    } 

    return secondObject[propertyKey]; 
} 

function mergeNestedObjects(firstObject, secondObject) { 
    var finalObject = {}; 

    // Merge first object and its properties. 
    for (var propertyKey in firstObject) { 
     finalObject[propertyKey] = mergeProperties(propertyKey, firstObject, secondObject); 
    } 

    // Merge second object and its properties. 
    for (var propertyKey in secondObject) { 
     finalObject[propertyKey] = mergeProperties(propertyKey, secondObject, firstObject); 
    } 

    return finalObject; 
}

सुंदर पुराने सवाल @AnthonyGrist के लिए, लेकिन उपयोगी हो सकता है। रिकर्सन का थोड़ा सा।

function mergeObjects(og, so) { 
    for (var key in so) { 
     if (typeof (og[key]) === 'object') { 
      mergeObjects(og[key], so[key]); 
     } else { 
      if (og[key] || typeof (og[key]) === 'boolean') { 
       og[key] = so[key]; 
      } 
     } 
    } 
    return og; 
} 

mergeObjects(ref, user);
