Given a link: http://example.com/hhhhhhhh/hhhh/ffff or http://www.example.com/hhhhhhhh/hhhh/ffff

How do I get a javascript code to print the "example.com(or www.example.com)" from the above url.

How do I also save it to in a variable.

@Charlene, you can use this


function getHost(urlStr) {
var hostResult = document.createElement("a";
hostResult.href = urlStr;
return hostResult.host;
};

so for...

var hostnm = getHost("https://www.nairaland.com/abc/123");

"hostnm" should produce "www.nairaland.com".

oh..you might need to validate your url string before using the function, and i tested it on firefox... you can confirm if it also works on IE (not so sure though..)

Hope that helps....

If you're using it on a web page, the location object is already provided with a host property which contains the current page's host name.


var domainName = location.host;



/* if you want ignore the port (eg, 127.0.0.1:80, return a string containing only values before the colon*/


hasPort = domainName.indexOf(':');
if(hasPort != -1)
{
domainName =
domainName.substring(0, hasPort);
}
