[Javascript] Split

[javascript@xxxxxxxxxx (Andrew Gibson)]

I'm trying to use split to separate out a file name from the complete
string.

from

  var txt="C:\Copy\new.html"

  I want to get "new.html"

Whenever I try to use "\"  I get a  Unterminated String variable error
  eg    var t=txt.split("\")

Obviously the problem is in trying to use the "\"  character which is an
escape char for JScript I beleive. But how can I solve my problem?
