Extract hostname name from string

Question

I would like to match just the root of a URL and not the whole URL from a text string. Given:

http://www.youtube.co         


        

Answer 1

I personally researched a lot for this solution, and the best one I could find is actually from CloudFlare's "browser check":

function getHostname(){  
            secretDiv = document.createElement('div');
            secretDiv.innerHTML = "x";
            secretDiv = secretDiv.firstChild.href;
            var HasHTTPS = secretDiv.match(/https?:\/\//)[0];
            secretDiv = secretDiv.substr(HasHTTPS.length);
            secretDiv = secretDiv.substr(0, secretDiv.length - 1);
            return(secretDiv);  
}  

getHostname();

I rewritten variables so it is more "human" readable, but it does the job better than expected.
