How to get responsive validation with jQuery in ASP.NET?

Hi, You have to use the JQuery validation plugin. You can download the plugin from http://jquery.bassistance.de/validate/demo/. Once you attach the plugin for all the fields define the validation rule and message like this

$().ready(function() { /
/ validate the comment form when it is submitted
$("#commentForm").validate(); // validate signup form on keyup and submit
$("#signupForm").validate(
{
rules:
{
firstname: "required", lastname: "required", username: { required: true, minlength: 2 }, password: { required: true, minlength: 5 },
confirm_password: { required: true, minlength: 5, equalTo: "#password" },
email: { required: true, email: true },
topic: { required: "#newsletter:checked", minlength: 2 },
agree: "required" },
messages: { firstname: "Please enter your firstname", lastname: "Please enter your lastname",
username: { required: "Please enter a username", minlength: "Your username must consist of at least 2 characters" },
password: { required: "Please provide a password", minlength: "Your password must be at least 5 characters long" },
confirm_password: { required: "Please provide a password", minlength: "Your password must be at least 5 characters long",
equalTo: "Please enter the same password as above" },
email: "Please enter a valid email address", agree: "Please accept our policy"
}
});
}

You have to attach this to the form
