        var el_up = document.getElementById('GFG_UP');
        var el_down = document.getElementById('GFG_DOWN');
        var JSObject = {
            'Geeks': {
                Geeks1: 'Geeks1_val',
                Geeks2: 'Geeks2_val'
            },
            'Computer Science portal': {
                Geeks_1: 'A Computer Science portal for Geeks.',
                Geeks_2: 'Geeks_2_val'
            }
        }
        el_up.innerHTML = "Click on the button to access the "+ 
              "key of object<br><br>"+ JSON.stringify(JSObject);
  
        function GFG_Fun() {
            el_down.innerHTML = 
              JSObject['Computer Science portal'].Geeks_1;
        }
    </script>

  • After clicking on the button:

Approach 2:

Example: This example implements the above approach.
