You can list cookies for current domain   function listCookies         var theCookies   document cookie split           var aString           for  var i   1   i  lt   theCookies length  i              aString    i         theCookies i-1      n             return aString      But you cannot list cookies for other domains for security reasons

I found this code on https   electrictoolbox com javascript-get-all-cookies   which worked for me better than the other solutions  function get cookies array          var cookies             if  document cookie  amp  amp  document cookie                  var split   document cookie split               for  var i   0  i  lt  split length  i                  var name value   split i  split  quot   quot                name value 0    name value 0  replace                        cookies decodeURIComponent name value 0      decodeURIComponent name value 1                            return cookies

No   The only API browsers give you for handling cookies is getting and setting them via key-value pairs  All browsers handle cookies by domain name only   Accessing all cookies for current domain is done via document cookie

Many people have already mentioned that document cookie gets you all the cookies  except http-only ones    I ll just add a snippet to keep up with the times   document cookie split      reduce  cookies  cookie    gt      const   name  value     cookie split      map c   gt  c trim       cookies name    value    return cookies            The snippet will return an object with cookie names as the keys with cookie values as the values   Slightly different syntax   document cookie split      reduce  cookies  cookie    gt      const   name  value     cookie split      map c   gt  c trim       return      cookies   name   value
