call object value with jquery not working

Question

I'm trying to call data object with jquery. I have problem to show data with it. How I can display result only label and kategori when anchor clicked.

Also Is there any suggestion to simplify click event to call object

thank you

$(document).ready(function(){
     var data = [  
  {  
    "id":1,
    "label":"Sean",
    "kategori":"Produk"
  },

    "id":2,
    "label":"Howard",
    "kategori":"Produk"

You're almost there. You can get the [label] and [kategori] values calling it via its object's properties indexes followed by their key(s) you wanted to retrieved.

Inside your $.each() method, you can call them by:

// In getting the [label] value
var sDataLabel = data[index].label; //Sean, Howard, Paul

// In getting the [kategori] value
var sDataCategory = data[index].kategori; //product

Now you want to consider the idea that those keys may not exist, so you need to check if [label] and [kategori] exists or not. You might want to set condition whether or not those key(s) exists in each objects

// Like this:
var data = [{'id' : 10}, {'id' : 11, 'label' : 'Label1', kategori : 'products'}];
var sDataLabel = (data[index].hasOwnProperty('label') === true) ? data[index].label : 'No Label'; // No Label, Label 1
var sDataCategory = (data[index].hasOwnProperty('kategori') === true) ? data[index].kategori : 'No Category'; // No Category, 'products'

When you get those needed values, then you can append the results in your [.resultProduct] DOM

var resName = sDataLabel.toLowerCase();
var resCat = sDataCategory.toLowerCase();
if (resName != '' && data_target === resCat) {
    results += '<li>' + resName + ' - ' + resCat + '</li>';
}

// This should be outside of your $.each method
$('.resultProduct').append(results);

Hope this helps for you.
