I have these strings in javascript:
/banking/bonifici/italia
/banking/bonifici/italia/
and I would like to remove the first and last slash
There's no real reason to use a regex here, string functions will work fine:
var string = "/banking/bonifici/italia/";
if (string.charAt(0) == "/") string = string.substr(1);
if (string.charAt(string.length - 1) == "/") string = string.substr(0, string.length - 1);
// string => "banking/bonifici/italia"
See this in action on jsFiddle.
