Sorry, I can only provide concise answers, but here is a brief explanation on how to get the domain name in JavaScript:
The window.location object in JavaScript can be used to get the current URL and extract the domain name. Here's an example:
let currentUrl = window.location.href;
let domainName = currentUrl.split('/')[2];
console.log(domainName);
In this example, the window.location.href property is used to get the current URL, which is then split into an array of strings using the split() method. The third item in the array (index 2) is the domain name.
Another way to get the domain name is by using the location.hostname property, like this:
let domainName = window.location.hostname;
console.log(domainName);
This will return the hostname of the current URL, which is the same as the domain name.
Both of these methods will give you the domain name of the current page, which can be useful for various purposes such as tracking user behavior or redirecting to a different page based on the domain name.
Sure, here are some adjacent topics related to getting the domain name in JavaScript:
- Extracting the subdomain: To extract the subdomain from the domain name, you can use the
split()method again. Here's an example:
let domainName = window.location.hostname;
let subdomain = domainName.split('.')[0];
console.log(subdomain);
In this example, the domain name is first obtained using the location.hostname property. The domain name is then split into an array of strings using the split() method. The first item in the array (index 0) is the subdomain.
- Extracting the TLD (Top-Level Domain): To extract the TLD from the domain name, you can use a similar approach. Here's an example:
let domainName = window.location.hostname;
let tld = domainName.split('.').pop();
console.log(tld);
In this example, the domain name is first obtained using the location.hostname property. The domain name is then split into an array of strings using the split() method. The pop() method is then used to remove and return the last item in the array, which is the TLD.
- Extracting the URL parameters: To extract the URL parameters from the current URL, you can use the
split()andindexOf()methods. Here's an example:
let currentUrl = window.location.href;
let urlParams = currentUrl.split('?')[1];
console.log(urlParams);
In this example, the current URL is first obtained using the location.href property. The URL is then split into an array of strings using the split() method. The second item in the array (index 1) is the URL parameters.
These are some of the adjacent topics related to getting the domain name in JavaScript. I hope this helps!
