So erhalten Sie Nachkommen von Json-Objekt

Question

Wie bekomme ich alle Nachkommen eines JSON-Objekts und filter es. das folgende ist ein C# code und ich möchte es in der eckigen seite tun können. Ein Teil davon ist ein Linq. Ich versuche alle Blattkinder auszuwählen.

e.g. if the following is the input, the answer could be at any level deep. 

{ 
"title": "first question?", 
    "yes": {"title": "answer A" }, 
    "no": { 
    "title": "second question?", 
    "yes": { 
     "title": "thirsd question?", 
     "yes": { 
     "title": "Fifth question?", 
     "yes": { 
      "title": "fourth question", 
      "yes": {"title": "answer D"}, 
      "no": { 
      "title": "another question?", 
      "yes": { "title": "answer E" }, 
      "no": {"title": "answer F"} 
      } 
     }, 
     "no": {"title": "answer B"} 
     }, 
     "no": {"title": "Answer F"} 
    }, 
    "no": {"title": "Answer G"} 
    } 
} 

The output would be: 

["answer A", "answer B", "answer D", "Answer F", "Answer G", "answer E"]

"title": "first question?", 
 
    "yes": {"title": "answer A" }, 
 
    "no": { 
 
    "title": "second question?", 
 
    "yes": { 
 
     "title": "thirsd question?", 
 
     "yes": { 
 
     "title": "Fifth question?", 
 
     "yes": { 
 
      "title": "fourth question", 
 
      "yes": {"title": "answer D"}, 
 
      "no": { 
 
      "title": "another question?", 
 
      "yes": { "title": "answer E" }, 
 
      "no": {"title": "answer F"} 
 
      } 
 
     }, 
 
     "no": {"title": "answer B"} 
 
     }, 
 
     "no": {"title": "Answer F"} 
 
    }, 
 
    "no": {"title": "Answer G"} 
 
    } 
 
} 
 
var titles=[]; 
 
getTitle(obj); 
 
function getTitle(obj){ 
 
    var keyLen=Object.keys(obj).length; 
 

 
    Object.keys(obj).forEach(function(key){ 
 
     if(keyLen==1 && key=="title") 
 
      titles.push(obj[key]); 
 
     else if(obj[key] instanceof Object) 
 
      getTitle(obj[key]); 
 
    }); 
 

 
} 
 

 
console.log(titles);

hoffe, das hilft
