3. Origin: For applications with subdomains, 'window.location.origin' gives you the protocol, host, and port in one string, e.g., 'https://sub.example.com'.
4. Document Domain: Access the domain of the current document with 'document.domain', which can help with cross-domain communication in iframes or subdomains.

jQuery Methods for Getting Current Domain

Getting the current domain using jQuery is straightforward and enhances your web development experience. By leveraging jQuery methods, you can easily access and display the current domain in your web applications. Here are a few ways to do it:

1. Use 'window.location.hostname': This returns just the domain name, like "example.com".
2. Get the full URL with 'window.location.href': This provides the complete address, useful for logging or navigation.
3. Extract the domain using 'document.domain': This may return the parent domain if you're in a subdomain.
4. Implement dynamic updates: Combine jQuery with 'window.location' to display the current domain right when the page loads.

You can create a simple jQuery function that selects an HTML element and updates its content with the current domain. For instance:

'''javascript

$(document).ready(function() {

$('#domainDisplay').text(window.location.hostname);

});

'''

This example guarantees that your web app reflects the current domain dynamically, enhancing user interaction.
