list out checklist of different kind of url validation using jquery

Basic URL Format Validation(starts with https/ftp)
Protocol Restriction using startswith (http or https)
startsWith http and includes social site keywords
Social url Length Limitations

Basic URL Format Validation:

Ensure the URL starts with a valid scheme and check for valid characters.
Example:

$('#urlInput').on('input', function() {
    const userInput = $(this).val();
    const urlRegex = /^(https?|ftp):\/\/[^\s/$.?#].[^\s]*$/;
    const isValidUrl = urlRegex.test(userInput);

    // Handle validation result (e.g., update UI, show/hide error messages)
});

Protocol Restriction:

If your application only accepts specific protocols, restrict the input to those protocols.
Example:

$('#urlInput').on('input', function() {
    const userInput = $(this).val();
    const allowedProtocols = ['http', 'https'];
    const isValidProtocol = allowedProtocols.some(protocol => userInput.startsWith(protocol));

    // Handle validation result
});

Domain Validation:

Check if the domain is valid (exists and has a valid DNS record).
Example:

$('#urlInput').on('input', function() {
    const userInput = $(this).val();
    const isValidDomain = /\.[a-z]{2,}$/.test(userInput) && userInput.indexOf(' ') === -1;

    // Handle validation result
});

Path Validation:

Ensure that the path portion of the URL is well-formed.
Example:

$('#urlInput').on('input', function() {
    const userInput = $(this).val();
    try {
        const path = new URL(userInput).pathname;
        // Valid path
    } catch (error) {
        // Invalid path
    }
});

Query Parameter Validation:

If the URL contains query parameters, validate them.
Example:

$('#urlInput').on('input', function() {
    const userInput = $(this).val();
    const isValidQuery = /^[a-zA-Z0-9=&]+$/.test(new URL(userInput).searchParams.toString());

    // Handle validation result
});

Fragment Identifier Validation:

If the URL contains a fragment identifier, validate it.
Example:

$('#urlInput').on('input', function() {
    const userInput = $(this).val();
    const isValidFragment = !new URL(userInput).hash.startsWith("#");

    // Handle validation result
});

Basic URL Format Validation:

Ensure the URL starts with a valid scheme (https://) and check for valid characters.
Example:

$('#socialUrlInput').on('input', function() {
    const userInput = $(this).val();
    const urlRegex = /^https:\/\/(www\.)?facebook\.com\/[a-zA-Z0-9.]+$/;
    const isValidFacebookUrl = urlRegex.test(userInput);

    // Handle validation result
});

Domain Validation:

Check if the URL belongs to the expected social media domain.
Example:

$('#socialUrlInput').on('input', function() {
    const userInput = $(this).val();
    const validSocialDomains = ['facebook.com', 'twitter.com', 'instagram.com'];
    const isValidSocialUrl = validSocialDomains.some(domain => userInput.includes(domain));

    // Handle validation result
});

Specific Social Media Validation:

Customize validation for specific social media platforms.
Example (for Facebook):

$('#socialUrlInput').on('input', function() {
    const userInput = $(this).val();
    const isValidFacebookUrl = userInput.startsWith('https://www.facebook.com/');

    // Handle validation result
});

Profile/Page Validation:

Check if the URL points to a user profile or a page on the social media platform.
Example (for Facebook):

$('#socialUrlInput').on('input', function() {
    const userInput = $(this).val();
    const isValidFacebookProfile = /\/(profile|pages)\//.test(userInput);

    // Handle validation result
});

Handle Vanity URLs:

Consider handling vanity URLs if applicable for the social media platform.
Example (for Facebook):

$('#socialUrlInput').on('input', function() {
    const userInput = $(this).val();
    const isValidFacebookVanityUrl = /\/[a-zA-Z0-9.]+\/?$/.test(userInput);

    // Handle validation result
});

Length Limitations:

Set a maximum length for the social media URL to prevent abuse or errors.
Example:

$('#socialUrlInput').on('input', function() {
    const userInput = $(this).val();
    const maxUrlLength = 255;
    const isWithinMaxLength = userInput.length <= maxUrlLength;

    // Handle validation result
});

These examples are tailored for Facebook, but you can adapt them for other social media platforms by adjusting the URL patterns and validation rules accordingly. Ensure that the rules align with the structure of the social media URLs you're expecting from users.

// Assuming 'url' is the variable containing the URL

if (url.includes('facebook') && (url.startsWith('http://') || url.startsWith('https://'))) {
  // The URL contains 'facebook' and starts with either 'http' or 'https'
  console.log('Valid Facebook URL');
} else {
  // Either 'facebook' is not present or the URL doesn't start with 'http' or 'https'
  console.log('Invalid Facebook URL');
}
