javascript - 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.

You can use:

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