disable input field on button click Jquery

Here is how you can disable an input field at the click of a button:

Step 1. Get the specified botton and input elements by using selector $("#id")

Step 2. Add an onclick event listener to the button element

Step 3. Set disabled attribute to input element

Here is the HTML that will be used for the example:

HTML

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>wecode101 disable input on click Jquery</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
</head>
<body>
  <main>
        <!--Main layout-->
    <div class="container">
        <div class="col-9 pt-5 mx-auto">
            <form>
              <div class="mb-3">
                <label for="name" class="form-label">name</label>
                <input type="text" class="form-control" id="name"/>
              </div>
              <button type="submit" class="btn btn-primary" id="s-btn">Submit</button>
            </form>
        </div>
    </div>
  </main>
</body>
</html>

Let's look at a couple of ways to disable an input based on the steps above:

Option 1. Set disable attribute using attr() method

$( "#s-btn" ).click(function(){
    event.preventDefault(); //prevents page refresh on submit
    $("#name").attr("disabled", true);
});

Option 2. Set disable attribute using prop() method

$( "#s-btn" ).click(function(){
    event.preventDefault(); //prevents page refresh on submit
    $("#name").prop("disabled", true);
});
