How do I validate form inputs with jQuery

Validating form inputs is an essential part of web development to ensure that the data submitted by users is accurate and formatted correctly. jQuery provides a simple way to validate form inputs with its built-in methods and event handling capabilities.

Example of jQuery Form Validation:


        $(document).ready(function() {
            $("form").on("submit", function(event) {
                var isValid = true;
                var email = $("#email").val();
                var password = $("#password").val();
                
                // Clear previous error messages
                $(".error").remove();

                // Validate email
                if(!email) {
                    isValid = false;
                    $("#email").after('Email is required');
                } else if(!isEmail(email)) {
                    isValid = false;
                    $("#email").after('Invalid email format');
                }

                // Validate password
                if(password.length < 6) {
                    isValid = false;
                    $("#password").after('Password must be at least 6 characters');
                }

                // Prevent form submission if validation fails
                if(!isValid) {
                    event.preventDefault();
                }
            });

            function isEmail(email) {
                var regex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
                return regex.test(email);
            }
        });
