remove duplicate forward slashes from the URL

Question

How can I remove duplicate forward slashes from the a url, but keep the // which comes after http: so that the URL does not break.

http://localhost//example/author/admin/// 

should be

http://localhost/example/author/admin/ 

I'm trying this, but it will remove only the last slash. I want to remove all double

abc = 'http://localhost//example/author/admin///'; clean_url = abc.replace(/\/$/,''); alert(clean_url); 

The following checks only three slashes.

clean_url = abc.replace("///", ""); alert(clean_url); 

I want to remove all the duplicate slashes.

Answer 1

You can use:

abc.replace(/([^:]\/)\/+/g, "$1");
