You can do this to get domain name from url,email,website,with http started,only domain name

var str=inputAddress;
      var patt1 = "(http://|https://|ftp://|www.|[a-z0-9._%+-]+@)([^/\r\n]+)(/[^\r\n]*)?";
var result = str.match(patt1);
var domain=result===null?str:result[2];
return domain.toString().startsWith("www.")?domain.toString().slice(4):domain;
