🚀 Description

Introducing the NFSFU234 Form Validation library – yes, it's my very first attempt at creating something useful for the coding world. This little JavaScript gem is all about making sure your HTML form elements play nice and follow the rules. 🎉👨‍💻

Now, I'm no expert, but I figured that validating forms could be a lot less painful. So, I cooked up NFSFU234 Form Validation. It's lightweight, beginner-friendly, and it's got a soft spot for textarea fields – those underappreciated champs. 📝🕶️

Look, I'm not promising to solve every validation puzzle out there, but I did manage to make things easier. You can customize error messages to sound as friendly or as stern as you like. And those mandatory fields? Yeah, I've got their back. ✅🔒

Oh, and if you're into stylish apps, NFSFU234 Form Validation offers ways to show errors that suit your app's vibe – whether it's neat little inline notes or those snazzy pop-up modals. 🎨💥

So, yeah, this is my debut library. I'm still learning the ropes, but I thought, why not share what I've got? Give NFSFU234 Form Validation a spin. It might not be perfect, but hey, it's my first shot at making developers' lives a tad easier. Enjoy! 🚀🌟

By executing this command, you're well on your way to enjoying the benefits of the NFSFU234 Form Validation library. 📦🚀

🏁 Initialization

To harness the power of the NFSFU234 Form Validation library, you must first create an instance of the library with the appropriate parameters. Below are illustrative examples showcasing how to forge an instance with form particulars and AJAX options.

Example 1: Elementary Embarkation

In this scenario, we'll craft a straightforward NFSFU234 Form Validation instance sans any supplementary parameters. The library will adeptly detect the form with the ID 'jsSubmit' and inaugurate the validation process.

// Create a fundamental NFSFU234 Form Validation instance
const formValidator = new NFSFU234FormValidation();

Example 2: Customized Form Insights and AJAX Artistry

This exemplar unveils the creation of a bespoke NFSFU234 Form Validation instance, replete with tailored form specifics and AJAX orchestrations.

// Example custom error messages for your form
const customErrorMessages = {
  "text": "EMPTY FIELD",
  "select": "SELECT FIELD IS REQUIRED",
  "email": {
    "empty": "EMPTY EMAIL",
    "format": "The email is not in the right format",
  },
  // ... Other field types and messages
};

// Example form details object
const formDetails = {
  form: "myForm", // Replace "myForm" with the ID of your form or the actual HTML element of your form (recommended)
  isErrorMessageInline: true,
  customErrorMessages: customErrorMessages,
};

// Example AJAX options object
const ajaxOptions = {
  url: "login.php",
  RequestMethod: "POST",
  RequestHeader: {
    "Content-Type": "application/json",
  },
};

// Forge a customized NFSFU234 Form Validation instance
const formValidator = new NFSFU234FormValidation(formDetails, ajaxOptions);

In the second example, we furnish tailor-made error messages for the form fields and outline AJAX options for form submission. This approach empowers granular customization and mastery over the validation and form submission processes.

Note: If you initialize an instance of the NFSFU234 Form Validation Library without providing parameters, it will seamlessly detect the form with the ID 'jsSubmit' or the first form on the page in the absence of a form ID. This streamlined approach suits scenarios where you're working with a single form and prefer a simplified setup without additional configurations. 🚀👨‍💻

🚀 Usage

The NFSFU234 Form Validation Library is a versatile toolbox that empowers you to validate forms, submit them, and handle AJAX requests effortlessly. Below, you'll find a breakdown of how to wield each function listed in the table above. With these tools at your disposal, you'll be equipped to create sleek and reliable form interactions. Let's dive in! 🛠💡

`submit()`

The submit function is used to submit a form. When you call this function, you are going to be automatically validating the form and then it will process for submitting.

formValidator.submit();

`validate():boolean`

The validate() function is used to validate a form. When you call this function, you are going to validating the form and will return a boolean value (true or false) to indicate if the form meets it's requirments. If it does not meet the requirements, the error messages will be displayed.


if ( formValidator.validate() )
{
  console.log("Form Validation Success");
}
else
{
  console.error("Form Validation Failed");
}

`isEmail(email: string): boolean`

The isEmail function checks if the given email is in a valid email format and returns a boolean value.

const isValidEmail = formValidator.isEmail('example@example.com');
console.log(isValidEmail); // true or false

`isURL(url: string): boolean`

The isURL function checks if the given string is a valid URL and returns a boolean value.

const isValidURL = formValidator.isURL('https://www.example.com');
console.log(isValidURL); // true or false

`isZipcode(zipcode: string): boolean`

The isZipcode function checks if the given string is a valid ZIP code and returns a boolean value.

const isValidZipcode = formValidator.isZipcode('12345');
console.log(isValidZipcode); // true or false

`generateRandomPassword(): string`

The generateRandomPassword function generates a random password between the length of 8 and 16 and it will return the password generated.

const randomPassword = formValidator.generateRandomPassword();
console.log(randomPassword); // A random password of varying length between 8 and 16 with special characters

`checkPassword(password: string, shouldIncludeSymbol: bool): boolean`

The checkPassword function checks the strength of the provided password and returns a boolean value indicating if it meets the required criteria (e.g., minimum length, 1 small case letter, 1 capital case letter, 1 number.). It also accepts a second paramter shouldIncludeSymbol which is of boolean type. If the value is set to true, the function will check the password and return true if the password contains all the requirements (e.g., minimum length, 1 small case letter, 1 capital case letter, 1 number and 1 symbol)

const isStrongPassword = formValidator.checkPassword('StrongP@ssword123');
console.log(isStrongPassword); // true or false

const isStrongPassword1 = formValidator.checkPassword('StrongP@ssword123', true);
console.log(isStrongPassword1); // true or false

`verifyPassword(password1: string, password2: string, isHashed = false): Promise<boolean>`

The verifyPassword function asynchronously compares two passwords, supporting both hashed and plaintext passwords. If isHashed is true, it uses bcrypt.compare to compare hashed passwords. If isHashed is false, it directly compares plaintext passwords. Returns a Promise resolving to true if passwords match, and false otherwise or in case of an error.

(async () => {
    try {
        const isPasswordMatch = await formValidator.verifyPassword(password, password2);
        console.log( isPasswordMatch); // true or false
    } catch (error) {
        console.error(error);
    }
})();

`getFormDetails(form: HTMLFormElement)`

Fetches all values of the inputs with a name or data-attr-name HTML attributes on a form element like input, select, textareas, etc.

// Using the default form you passed at creating the instance
const myFormDetails = formValidator.getFormDetails();
console.log(myFormDetails); // Logs either an object or false

// OR

// Using a diffrent form than the one you created or passed in your instance.
const form = document.getElementById('myForm');
const myFormDetails = formValidator.getFormDetails(form);
console.log(myFormDetails); // Logs either an object or false

`togglePasswordVisibility(icons: Object, form: HTMLFormElement or string)`

The togglePasswordVisibility function is used to enable the password visibility toggle feature for password input fields within a given form. When called, it allows users to toggle the visibility of their password, displaying plain text or masked characters (password dots).

Parameters:

icons (optional): The icons parameter is an optional parameter that allows you to customize the icons used for showing and hiding the password. It expects an object with two properties: 'show' and 'hide'. You can provide any text or HTML content as the icon for showing and hiding the password. If this parameter is not provided, the default texts "show" for show and "hide" for hide will be used.
form(optional): The form parameter accepts either an HTMLFormElement or a string representing the ID of the form element that contains the password inputs. If you pass a string as the form ID, the function will search for the form element in the document using the provided ID. If the form is not found, it will use the form from the instance of the library.

Example:

<!-- HTML CODE -->
<div class='input'>
    <input type="password" id="passwordField" placeholder='Type Password'>
    <button class="js-togglePassword">Toggle</button>
</div>

// Assuming you have already created an instance of the library named 'formValidator'
formValidator.togglePasswordVisibility({ 'show': '👁️', 'hide': '🙈' }, 'myForm');

`ajax(AJAXOptions: Object): Promise`

The ajax function is used to make an AJAX request using the provided AJAXOptions. It returns a Promise that will resolve to the server's response (in JSON format) or reject with an error.

Parameters:

AJAXOptions: An object containing the following AJAX request options:
- url (required): The URL to which the AJAX request will be sent.
- RequestMethod (required): The HTTP method for the AJAX request, such as 'GET', 'POST', 'PUT', 'DELETE', etc.
- RequestHeader (required): An object representing the request headers to be included in the AJAX request.
- RequestType (optional): The response type for the AJAX request. This parameter is optional and defaults to 'json'.

Returns:

The ajax function returns a Promise that will resolve to the server's response (in JSON format) if the request is successful or reject with an error if there is an issue with the request.

Example:

// Assuming you have already created an instance of the library named 'formValidator'

const AJAXOptions = {
  url: 'https://api.example.com/data', // URL for the AJAX request
  RequestMethod: 'POST', // Request method
  RequestHeader: {
    'Content-Type': 'application/json', // Example request header
    // Add other request headers if needed
  },
};

formValidator.ajax(AJAXOptions)
  .then((response) => {
    // Success: Server response received in JSON format
    console.log('Request successful', response);
  })
  .catch((error) => {
    // Error: AJAX request failed or rejected
    console.error('Request failed', error);
  });

// OR

(async () => {
    try {
        const response = await formValidator.ajax(AJAXOptions);
        console.log(response);
    } catch (error) {
        console.error(error);
    }
})();

`getAJAXResponse(): Promise | false`

The getAJAXResponse function is used to retrieve the response from the last AJAX request made using the ajax function. It returns the AJAX response as a Promise if available or false if the AJAX request has been resolved.

Note: This function is primarily used when submitting a form via AJAX, and the user wants to access the response from the server database. If you wish to perform an AJAX request and want to access the server's response, you should use the ajax() function provided by the library.

Example Usage:

// Assuming you have already created an instance of the form validation library named 'formValidator'

// Step 1: Submit the form using AJAX
formValidator.submit(formDetails, ajaxOptions);

// Step 2: Get the AJAX response after the form is submitted
const submitButton = document.querySelector("#submitButton");
submitButton.addEventListener('click', () => {
    const ajaxResponse = formValidator.getAJAXResponse();
    console.log(ajaxResponse);
});

- type (required): The type of error message container you would like to use. You have 2 options either inline or modal.
- message (required): The message that is to be displayed.
- duration (required): The duration for the message to be shown
- element (required): This is a HTML Element where the error container will be passed to. It can be an input or textarea element or probally a section or div element, whichever meets the requirements for the error you want to display.
- success (optional): You are indicating if this is a success or failure message. If not set, the default of failure will be used.

Usage

// Assuming you have already created an instance of the library named 'formValidator'

const form = document.getElementById('form');

const errorDetails = {
  type : 'modal',
  message: 'Hello World👋',
  duration: 3000,
  element: form,
  success: false,
}

formValidator.displayError(errorDetails);

Example

Assumming you make a request to an API and you will need to display the response message to the user, the perfect way to that is to use the ajax() function thereafter you can use the displayError() function and in your type attribute, it is most preffered to use modal type. Assuming the response has a status and message attribute on response. Let's take a look at how this works.

// Assuming you have already created an instance of the library named 'formValidator'


// Getting the HTML Form ELement from the Document
const form = document.getElementById('form');

const AJAXOptions = {
  url: 'https://api.example.com/data', // URL for the AJAX request
  RequestMethod: 'GET', // Request method
  RequestHeader: {
    'Content-Type': 'application/json', // Example request header
    // Add other request headers if needed
  },
};

formValidator.ajax(AJAXOptions)
  .then((response) => {
    // Success: Server response received in JSON format
    console.log('Request successful', response);

    // Getting the neccessary information from the response
    const status = response.status;
    const message = response.message;

    let errorDetails;

    // Checking if the status of the respond code is not 200(ok)
    // Then we set the message to the message variable, the element to the form variable,  set duration to 3 seconds  and then set the success attribute to false.
    if ( status != 200 )
    {
        errorDetails = {
            type : 'modal',
            message: message,
            duration: 3000,
            element: form,
            success: false,
        }
    }
    else
    {
      // Response is 200(ok) so we set the success attribute to be true
      // We assumme this is a success message
        errorDetails = {
            type : 'modal',
            message: message,
            duration: 3000,
            element: form,
            success: true,
        }
    }


    // We call the displayError function to display the error.
    formValidator.displayError(errorDetails);


  })
  .catch((error) => {
    // Error: AJAX request failed or rejected
    console.error('Request failed', error);
  });

`loading(message, submitBtn = null):bool`

The loading() function is used to display a loading message in your button. This function is ideal if you choose to use the validate() function independly. Because you might wish for the users to know they are awaiting a response, so you can have a little message or animation you wish to show between validation and perhaps awaiting the results from the AJAX request.

Parameters:

message: This will contain the message or HTML contents you wish to insert into your Button or set as the value of the button.
submitBtn (optional): This is optional because assuming you have initialized the NFSFU234FormValidation Library, you would have had an inital form so the button or submit button found in the form will be used else you want a diffrent button, you can either pass the HTML Element or pass the ID of the button

Usage

// Assuming you have already created an instance of the library named 'formValidator'

// Using the Default Button
formValidator.loading('Loading Message');

// Using a Difffrent Button || Assuming your form has diffrent buttons
const button = document.getElementById('btnId');
formValidator.loading('Loading Message', button);

`isOnline(): boolean`

The isOnline function checks if the current environment is a browser and determines whether the browser is online. It does this by examining the navigator.onLine property, which indicates the online status of the browser. This function is useful when you need to verify the browser's connectivity status before making network requests or performing actions that depend on internet access.

The function returns a boolean value, true if the browser is online and false if it's not.

const isBrowserOnline = formValidator.isOnline();
console.log(isBrowserOnline); // true or false

`reset(form?: HTMLFormElement): boolean`

The reset function provides a convenient way to reset form elements within a given HTML form or the internal form of a validation tool. It resets input fields, textareas, selects, radios, and checkboxes to their default values or empty states, ensuring that the form is in a clean state.

You can optionally pass a form parameter to specify a different form to reset; otherwise, it will operate on the internal form. This function can be particularly helpful when you want to clear user inputs and start fresh after a form submission or user interaction.

The function returns a boolean value, true if the reset operation is successful, and false if any issues occur during the reset process.

const isResetSuccessful = formValidator.reset(); // Resets the internal form
console.log(isResetSuccessful); // true or false
