Phone validation while validating a HTML form is a very important point. In this page we shall discuss how to validate a phone number having a specific format e.g. (111) 222-3333.


Step 1: Create a Form to Input Phone Number

To create the form use the following code.

<h1>Phone Number Validation</h1>
<form method="post" action="action.php">
<label>Phone Number</label>
<input type="text" name="phonenumber" id="phonenumber">
<input type="submit" value="Submit">

Step 2: Function to Validate Phone Number

The function will validate numbers, spaces and will automatically format the phone number to (111) 222-3333, when the number of digits added to textbox is 10.

    $cf = $('#phonenumber');
	phone = $(this).val();
	phone = phone.replace(/[^0-9]/g,'');
	if (phone.length != 10)
	    alert('Phone number must be 10 digits.');
