Convert string with dot notation to JSON

by

For those of you who are looking for solution without the _x in the object try this code. A slight modification of the above code (which is brilliant)

stringToObj = function(path,value,obj) {
  var parts = path.split("."), part;
  var last = parts.pop();
  while(part = parts.shift()) {
   if( typeof obj[part] != "object") obj[part] = {};
   obj = obj[part]; // update "pointer"
  }
 obj[last] = value;
}

As bonus the above code will work if you want to update parts of an existing object 🙂

 var obj = {a:{b:3}};
 stringToObj("a.b",10,obj);
 console.log(obj); //result : {a:{b:10}}
