rated 0 times [ 77] [ 3] / answers: 1 / hits: 25655 / 10 Years ago, wed, august 20, 2014, 12:00:00

I have a javascript object width depth.

I need to know the exact path from this key within the object ex: obj1.obj2.data1

I already know the key is data1, the value is 123.

My javascript object look like this

{

    obj1: {

        obj2: {

            data1: 213,

            data2: 1231,

            obj3: {

                data: milf

            }

        }

    },

    obj4: {

        description: toto

    }

}

How could I achieve that ?

here is a jsfiddle : http://jsfiddle.net/3hvav8xf/8/

I think recursive function can help to you (Updated version, to check value)

function path(c, name, v, currentPath, t){

    var currentPath = currentPath || root;



    for(var i in c){

      if(i == name && c[i] == v){

        t = currentPath;

      }

      else if(typeof c[i] == object){

        return path(c[i], name, v, currentPath + . + i);

      }

    }



    return t + . + name;

};



console.log(path({1: 2, s: 5, 2: {3: {2: {s: 1, p: 2}}}}, s, 1));
