How to get protocol, domain and port from URL using JavaScript ?
The protocol, domain, and port of the current page can be found by two methods:
Method 1: Using location.protocol, location.hostname, location.port methods: The location interface has various methods that can be used to return the required properties.
- The location.protocol property is used to return the protocol scheme of the URL along with the final colon(:).
- The location.hostname is used to return the domain name of the URL.
- The location.port property is used to return the port of the URL. It returns nothing if the port is not described explicitly in the URL.
Syntax:
protocol = location.protocol; domain = location.hostname; port = location.port;
Example:
<!DOCTYPE html> <html> <head> <title> Get protocol, domain, and port from URL </title> </head> <body> <h1 style="color: green"> GeeksforGeeks </h1> <b> Get protocol, domain, and port from URL </b> <p> Protocol is: <span class="protocol"></span> </p> <p> Domain is: <span class="domain"></span> </p> <p> Port is: <span class="port"></span> </p> <button onclick="getDetails()"> Get protocol, domain, port </button> <script type="text/javascript"> function getDetails() { protocol = location.protocol; domain = location.hostname; port = location.port; document.querySelector('.protocol').textContent = protocol; document.querySelector('.domain').textContent = domain; document.querySelector('.port').textContent = port; } </script> </body> </html> |
