This one looks like it would fit your description:

• jQuery plugin:validation (Homepage)
• demo
• API docs

Here's a snippet of code copied from the source of the demo:

// 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"
    }
});
