Displaying JSON Data using jQuery

Question

I am trying to display my JSON data in my HTML UI, The JSON Object is returning but I am not able to display the object.

And here is my JSON object structure:

Here is my JS File:

    $(document).ready(function() {
  console.log("ready!");

  // on form submission ...
  $('form').on('submit', function() {

    console.log("the form has beeen submitted");

    // grab values
    valueOne = $('input[name="perfid"]').val();
    valueTwo = $('input[name="hostname"]').val();
    valueThree = $('input[name="iteration"]').val();


    console.log(valueOne)
    console.log(valueTwo)
    console.log(valueThree)



    $.ajax({
      type: "POST",
      url: "/",
      datatype:'json',
      data : { 'first': valueOne,'second': valueTwo,'third': valueThree},
      success: function(result) {
            $('#result').html(result.sectoutput.summarystats.Avg.Exempt)
      },
      error: function(error) {
        console.log(error)
      }
    });

  });

});

I get nothing in my result div.

EDIT:

Here is my json.stringify(result) output on my UI:

i feel you should stop the form submit:

$('form').on('submit', function(e) { // <-----add arg to get the event as e.
  e.preventDefault(); //<----add this to stop the form submission

  console.log("the form has beeen submitted");

  // grab values
  valueOne = $('input[name="perfid"]').val();
  valueTwo = $('input[name="hostname"]').val();
  valueThree = $('input[name="iteration"]').val();

  console.log(valueOne)
  console.log(valueTwo)
  console.log(valueThree)

  $.ajax({
    type: "POST",
    url: "/",
    datatype: 'json',
    data: {
      'first': valueOne,
      'second': valueTwo,
      'third': valueThree
    },
    success: function(data) { //<----this confused so change it to "data"
      var res = data.result.sectoutput.summarystats.Avg.Exempt;                 
      var p = '<p><pre>'+res+'</pre></p>';
      $('#result').append(p); // now append the Exempts here.
    },
    error: function(error) {
      console.log(error)
    }
  });
});

Because if you don't then form will submit and page gets refreshed and the data from ajax won't be reflected.

Updates:

I guess the actual problem lies here:

    success: function(data) { //<----this confused so change it to "data"
      var res = data.result.sectoutput.summarystats.Avg.Exempt;                 
      var p = '<p><pre>'+res+'</pre></p>';
      $('#result').append(p); // now append the Exempts here.
    },

The most confusing part in the code was the usage of result key. Better to have a different name in the success callback as i used data which is denoting the response data from ajax which is an object. So we just need to target it like:

var res = data.result.sectoutput.summarystats.Avg.Exempt;
