HTML | DOM attributes Property
  • Last Updated : 25 Jul, 2019

The attributes property in HTML DOM returns the group of node attributes specified by NamedNodeMap objects. The NamedNodeMap object represents the collection of attribute objects and can be accessed by index number. The index number starts at 0.

Syntax:

node.attributes

Return Value: It returns the NamedNodeMap object which is the collection of nodes.

Note: In Internet Explorer 8 and earlier versions, the attributes property will return a collection of all possible attributes for an element that can result in higher value than expected.

Example 1:






<!DOCTYPE html>
<html>
    <head>
        <title>
            HTML DOM attributes Property
        </title>
    </head>
      
    <body>
      
        <!-- Setting up an image -->
        <img id = "GFG" src
          
        <br>
        <button onclick = "myGeeks()">
            DOM attributes property
        </button>
          
        <p id = "demo"></p>
          
        <script>
            function myGeeks() {
                
            // It returns the number of nodes
            var x = document.getElementById("GFG").attributes.length; 
              
            // Display the number of nodes
            document.getElementById("demo").innerHTML = x; 
        }
        </script>
    </body>
</html>
