The HTML DOM setAttribute() method is used to get the value of the attribute of the element. By specifying the name of the attribute, it can set the value of that element. If the element is already present then its value is updated.

Syntax:

Object.setAttribute(attributename,value)

Parameters: This method accepts two parameters:

  • attributename: It is a string whose value is to be set.
  • value: It is a string value that is to be assigned to the attributename.

Return Values: This parameter does not return any values.

The below examples show the use of the setAttribute() method.

Example 1: In this example, we will add a href attribute to the anchor tag using the setAttribute() method.

HTML 
<!DOCTYPE html> <html> <body>     <h1 style="color:green">         Geeks for Geeks     </h1>     <h2>setAttribute() Method</h2>      <a id="geek">Click to go to geeksforgeeks.org</a>      <p>         Click the button below to add an href         attribute to the element above.     </p>      <button onclick="myFunction()">Click Me</button>      <script>         function myFunction() {           document.getElementById("geek").setAttribute           ("href", "https://www.geeksforgeeks.org");          }     </script> </body> </html>

Output:

Example 2: In this example, we will change the type of an input tag to a button using the setAttribute() method.

HTML 
<!DOCTYPE html> <html> <body>     <h1 style="color:green">         Geeks for Geeks     </h1>     <h2>setAttribute() Method</h2>      <input id="geeks" value="Hello Geek">      <p>         Click the button below to change the         input field to an input button.     </p>     <button onclick="changeType()">Change</button>      <script>         function changeType() {           document.getElementById("geeks").setAttribute("type", "button");          }     </script> </body> </html>

Output:
