How Do I Use Javascript To Get The Domain Name From A Link by Nobody: 2:01pm On Jul 12, 2015 |
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.... |

Charleen94: 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); } |
