Thank you. That expression is bringing back only itself, i.e. the element in the DP with the ID I'm testing against.
I'm hoping to have an element with an ID of '3', to bring back '31', '32', etc... I've adjusted the expression thinking it will do the trick but it doesn't seem to cut it: var pattern:RegExp = new RegExp(currentID + "\d*"); Doesn't this say as long as the test string has the currentID at the beginning plus any digits after it??? and then i test the string like this: activeID.match( pattern ) thanks for your help. matt --- In [email protected], thomas parquier <mailingli...@...> wrote: > > I'm not sure currentID is replaced in slash syntax, so : > var pattern:RegExp = new RegExp('^'+currentID); > should work. > > thomas > --- > http://www.web-attitude.fr/ > msn : thomas.parqu...@... > softphone : sip:webattit...@... <sip%3awebattit...@...> > téléphone portable : +33601 822 056 > > > 2009/5/3 fumeng5 <fume...@...> > > > > > > > Wow, works like a charm; big thanks. > > > > And if I want to test it against IDs with 3 characters I'm thinking that > > RegExes are the way to go.
