Given an object and the task is to access the object in which the key contains spaces. There are a few methods to solve this problem which are discussed below: 

Approach 1:

  • Create an object having space-separated keys.
  • Use square bracket notation instead of dot notation to access the property.

Example: This example implements the above approach. 

html

<h1 style="color:green;">
    GeeksforGeeks
</h1>
<p id="GFG_UP"></p>
<button onclick="GFG_Fun()">
    click here
</button>
<p id="GFG_DOWN"></p>
<script>
    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>

                    

Output:

Approach 2:

  • Create an object having space-separated keys.
  • Take the key in a variable and use that variable in place of the key (But, Here also square bracket notation will work).

Example: This example implements the above approach. 

html

<h1 style="color:green;">
    GeeksforGeeks
</h1>
<p id="GFG_UP"></p>
<button onclick="GFG_Fun()">
    click here
</button>
<p id="GFG_DOWN"></p>
<script>
    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() {
        var someKey = 'Computer Science portal';
        el_down.innerHTML = JSObject[someKey].Geeks_1;
    }
</script>

                    

Output:
