I have a application where i collect location of a particular client folder, where the user manually adds the location. But i need to validate the user entered location atleast whether any drive he has been specified. For eg:- "C: esttestfolderloc" is the expected input. If the user enters "testtestfolderloc" , javscript function need to capture it. Does anybody come with the same situation? anybody got better idea for to do the validation. :)
