jquery form validation Dan captcha input

A3 assignment At Salt Academy this time I made a jquery-plugin form validation with captcha input validate

first we create a table first in the hmtl file

on the css card I will use it to create files in the css
<div class="card">
        <form action="#" name="userForm" id="userForm" method="post">
            <h3>Jquery Form </h3>
            <div class="form-group">
                <input class="input" type="text" name="name" id="name" placeholder="Enter Name">
            </div>
            <div class="form-group">
                <input class="input" type="text" name="email" id="email" placeholder="Enter Email">
            </div>
            <div class="form-group">
                <input class="input" type="addres" name="addres" id="addres" placeholder="Enter Your addres">
            </div>
            <div class="form-group">
                <input class="input" type="number" name="ZipCode" id="ZipCode" placeholder="Enter Your Zip Code">
            </div>
            <div class="form-group">
                <input class="input" type="date" name="date" id="date" placeholder="Enter Your Birth day">
            </div>
            <div class="form-group">
                <input class="input" type="number" name="phone" id="phone" placeholder="Enter Your Phone">
            </div>
            <div class="form-group">
                <input class="input" type="password" name="password" id="password" placeholder="Enter Youre Password">
            </div>
            <div class="form-group">
                <input class="input" type="password" name="confirm_password" id="confirm_password" placeholder="Enter Confirm Password">
            </div>### we add lib from ajax jquery

> can be downloaded from the library or it can also be via the script link

"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"

"https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js">

we create a jquery file for the validation form

we create a validation rule in the field we are going to create which will throw an error if the form doesn't match the rules we created

$("#userForm").validate({
    rules:{
        name:{
            required: true,
            minlength: 3
        },
        email: {
            required: true,
            email: true
        },
        addres:{
            required: true,
            addres: true
        },
        ZipCode:{
            required: true,
            minlength:4
        },
        date:{
            required: true,
            date: true
        },
        phone:{
            required: true,
            minlength:12
        },
        password:{
            required: true,
            minlength: 5
        },
        confirm_password:{
            required: true,
            equalTo: '#password'
        },
    },
    messages:{
        name:{
            required: 'The Name field is required',
            minlength: 'You must enter at least 3 characters'
        },
        email: {
            required: 'The Email field is required',
            email: 'You must enter a valid email address'
        },
        addres: {
            required: 'The Addres field is required',
            adrres: 'You must enter youre addres'
        },
        ZipCode: {
            required: 'The Zip Code field is required',
            minlength: 'You must enter at least 4 digit'
        },
        date: {
            required: 'The Date field is required',
        },
        phone: {
            required: 'The Phone field is required',
            minlength: 'You must enter at least 12 digit'
        },
        password:{
            required: 'The Password field is required',
            minlength: 'You must enter at least 12 characters'
        },
        confirm_password:{
            required: 'The Confirm password field is required',
            equalTo: 'The Confirm password field must match with Password'
        },
    },

second we create a validation captcha with jquery

we will create a captcha variable for user validation on the form we are going to create

function CreateCaptcha() {
var alpha = new Array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9');
var i;
for (i = 0; i < 6; i++) {
var a = alpha[Math.floor(Math.random() * alpha.length)];
var b = alpha[Math.floor(Math.random() * alpha.length)];
var c = alpha[Math.floor(Math.random() * alpha.length)];
var d = alpha[Math.floor(Math.random() * alpha.length)];
var e = alpha[Math.floor(Math.random() * alpha.length)];
var f = alpha[Math.floor(Math.random() * alpha.length)];
}

> then we validate the captcha that we created in the previous create captcha variable

function ValidateCaptcha() { var string1 = removeSpaces(cd); var string2 = removeSpaces($('#UserCaptchaCode').val()); if (string1 == string2) { return true; } else { return false; } } // Remove Spaces

function removeSpaces(string) { return string.split(' ').join(''); }

// Check Captcha

function CheckCaptcha() {
let result = ValidateCaptcha();
if( $("#UserCaptchaCode").val() == "" || $("#UserCaptchaCode").val() == null || $("#UserCaptchaCode").val() == "undefined") {
    $('#WrongCaptchaError').text('Masukan Code Yang Berada Di gambar bawah.').show();
    $('#UserCaptchaCode').focus();
} else {
    if(result == false) {
    IsAllowed = false;
    $('#WrongCaptchaError').text('Captcha Salah! Silahkan Ulangi Lagi.').show();
    CreateCaptcha();
    $('#UserCaptchaCode').focus().select();
    }
    else {
    IsAllowed = true;
    $('#UserCaptchaCode').val('').attr('place-holder','Enter Captcha - Case Sensitive');
    CreateCaptcha();
    $('#WrongCaptchaError').fadeOut(100);
    $('#SuccessMessage').fadeIn(500).css('display','block').delay(5000).fadeOut(250);
    }
}

}
