how to put the result from Regexp.match in $1

Hi All

I want to extract some part of an url and use $1, here is my code

[CODE]
var x = location.href.match(//([^/]+).html$/) ? $1 : ‘nope’ ;
[/CODE]

For example, if I have the url [B][url]http://localhost/test[/url][/B] I get ‘nope’, but when I have [B][url]http://localhost/test/index.html[/url][/B] I want $1 to contain ‘index’, but instead I get an error message

$1 is not defined

Any suggestions how to do this ?

ps I prefer a one-liner!!

UPDATE: found the solution, its not $1 but RegExp.$1

Also in #JavaScript _↴
