How to convert ul li value into an array format in console with jquery

I have an structure of ul li contains some value,When I check the checkbox of one or multiple child element the value of that particular li should show along with its parent value in below array format in browser console.If I won't select any child,that value or its parent value should not show.Every every thing is working fine but here only problem is that child and its parents also showing for which I have not checked.I have updated the code in plunker https://plnkr.co/edit/koWZabX8OV88opxSDNIv?p=preview, Below is my code

$(".applybtn").click(function() {
  alert('sss');
  var getAllList = $('#leftNavBar ul').find('li.childData ul li');
  var getAllParents = $('#leftNavBar ul').find('li.parentNav');
  var getFilterData = [];
  $(getAllParents).each(function() {
    getFilterData.push({
      name: $(this).text().trim(),
      value: []

    });
  });
  $(getAllList).each(function() {
    if ($(this).find('input').prop("checked") == true) {
      var parent = $(this).closest("ul").closest("li").prev().text().trim();
      var getIndex = _.findIndex(getFilterData, ['name', parent]);
      var name = $(this).text().trim();
      getFilterData[getIndex].value.push(name);
    }
  });
  console.log(JSON.stringify(getFilterData));
});
.parentNav {
  background: red;
  font-size: 16px
}

.childData {
  background: #ccc;
}

.childData ul li {
  clear: both;
}

  </ul>
  <div class="applybutton"><button class="applybtn" type="button">Appply</button></div>
</div>

json format for output

 [{

            "value": ["child11", "child12"]
        }, {
            "name": "parent2",

        }, {
            "name": "parent3",
            "value": []
        }]

You can use the function $.text() to get the text inside of an element.

This approach finds the parentNav and then its children using the function $.siblings().

var obj = [];
$('.parentNav').each(function() {
  var childrenLis = $(this).siblings('.childData').find('li');
  obj.push({
    name: $(this).text(),
    value: childrenLis.toArray().map(l => $(l).text())
  })
});

console.log(obj);
.as-console-wrapper { max-height: 100% !important; top: 0; }

Putting that approach within your code

$(".applybtn").click(function() {
  var getFilterData = [];
  $('.parentNav').each(function() {
    var childrenLis = $(this).siblings('.childData').find('li');
    getFilterData.push({
      name: $(this).text(),
      value: childrenLis.toArray().map(l => $(l).text())
    })
  });
  console.log(JSON.stringify(getFilterData));
});
.parentNav {
  background: red;
  font-size: 16px
}

.childData {
  background: #ccc;
}

.childData ul li {
  clear: both;
}

    .as-console-wrapper { max-height: 100% !important; top: 0; }
