    hi everyone !
    could someone please help me to get the filename from the path ? knowing Javascript string command/operations wont help . ' var filename = this.substring(this.lastIndexOf("/") + 1, this.lastIndexOf(".")); ' max is returning an error about not existing function . perhaps regular expression would help ,but im also getting errors .and additionaly i would like to get rid of extension string too .
    would be great if some of you have a clue what to do in my case .
