taking off the http or https off a javascript string

Question

I have the following strings

http://site.com
https://site.com
http://www.site.com

how do i get rid of the http:// or https:// in javascript or jquery

Answer 1

var txt="https://site.com";
txt=/^http(s)?:\/\/(.+)$/i.exec(txt);
txt=txt[2];

for parsing links without http/https use this:

var txt="https://site.com";
txt=/^(http(s)?:\/\/)?(.+)$/i.exec(txt);
txt=txt[3];

Answer 2

var str = "https://site.com";

str = str.substr( str.indexOf(':') + 3 );

Instead of .substr(), you could also use .slice() or .substring(). They'll all produce the same result in this situation.

str = str.slice( str.indexOf(':') + 3 );

str = str.substring( str.indexOf(':') + 3 );

EDIT: It appears as though the requirements of the question have changed in a comment under another answer.

If there possibly isn't a http:// in the string, then do this:

var str = "site.com";

var index = str.indexOf('://');
if( index > -1 )
   str = str.substr( index + 3 );

Answer 3

Try with this:

var url = "https://site.com";
var urlNoProtocol = url.replace(/^https?\:\/\//i, "");
