I want to search a JSON object to check if it contains string values stored in an array. and figure out the parent elements.

var searchVal = ['name_1a','name_2y','name_3x'];



var json = {

location: {

        title1x: {

            1: name_1x,

            2: name_2x,

            3: name_3x,

        },

       title2y: {

            1: name_1y,

            2: name_2y,

            3: name_3y,

        },

    }



    object: {

        title1a: {

            1: name_1z,

            2: name_2z,

            3: name_3z,

        },

       title2b: {

            1: name_1a,

            2: name_2a,

            3: name_3a,

        },

    }

};

I want to pass the results into a function. And deal with them separate.

name_1a -> function(title2b, object)

name_2y -> function(title2y, object)

name_3x -> function(title1x, location) etc.

.
This is what I have tried so far. I can't seem to figure out how to gothrough the entire JSON object

var searchVal = ['name_1a','name_2y','name_3x'];

  for (var i=0 ; i < searchVal.length ; i++){

    for (var k=0 ; k < ????.length ; k++)

    {

      if (json.???????? == searchVal[i]) {

        results.push(???????);

        console.log(results);



      }

    }

  }
