Change input type value attribute in jQuery



Let’s say the following is our input type with value, “John Smith” −

<input type = 'text' value = 'John Smith' id = 'changeTheName' />

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

<input type = 'text' value = 'John Smith' id = 'changeTheName' />
<script>
   $('#changeTheName').attr('value', 'Please enter your name.......');
</script>
</body>
