How to Add Attributes to an HTML Element in jQuery?

To add attributes to an HTML element in jQuery, the attr() method can be used. This allows to set one or more attributes for a selected element, such as id, class, src, and href.

Approach:

Given an HTML document containing <label>, <input>, and <button> elements. The <input> element contains the type and id attribute. When the user clicks on the button, the jQuery function is called. We use $(selector).attr() method to add the attributes. Here, we are adding the placeholder attribute to the input field.

Syntax:

$("#add-attr").click(function () {
    $("#addAttr").attr("placeholder", "GeeksforGeeks");
});

Example: This example shows the use of the above-explained approach.

HTML 
<!DOCTYPE HTML> <html>  <head>     <meta http-equiv="Content-Type"            content="text/html; charset=utf-8">     <script src= "https://code.jquery.com/jquery-3.5.1.min.js">     </script> </head>  <body style="text-align: center;">      <h4>         How to add attributes to an HTML element in jQuery?     </h4>      <label for="addAttr"></label>     <input type="text" id="addAttr">      <button id="add-attr">Add Placeholder Attribute</button>     <script>         $(document).ready(function () {             $("#add-attr").click(function () {                 $("#addAttr").attr("placeholder", "GeeksforGeeks");             });         });     </script> </body>  </html>
