Syntax
How to use the onreset attribute in HTML?
The onreset attribute can be included in the <form> tag. Here is the basic syntax:
<form onreset="JavaScript function or code here">
</form>
This syntax allows you to define a JavaScript function or code to be executed when the form is reset.
Example
Example of onreset attribute in a form
Below is a responsive example of how to use the onreset attribute within a form. When the reset button is clicked, a message will be alerted to the user, indicating that the form has been reset.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>onreset Example</title>
<script>
function showResetMessage() {
alert("The form has been reset!");
}
</script>
</head>
<body>
<form onreset="showResetMessage()">
<label for="name">Name:</label>
<input type="text" id="name" name="name"><br>
<label for="email">Email:</label>
<input type="email" id="email" name="email"><br>
<input type="reset" value="Reset">
</form>
</body>
</html>
In this example, when the user fills in the form fields and clicks on the reset button, an alert will pop up displaying the message “The form has been reset!”. This simple demonstration shows how effective the onreset attribute can be in providing immediate feedback to users.
