Re: FLASH: How to validate forms in action script????

[Branden Hall]

Okay.... here you roll...


On (Press)

      Set Variable: "size" = length(userinput)

      Set Variable: "badInput" = false

      Set Variable: "loop1" = 1

      Loop While (loop1<=size and badInput=false)

            Set Variable: "loop2" = 0

            Set Variable: "isNumber" = false

            Loop While (loop2<=9 and isNumber=false)

                  If (substring(userinput,loop1,1) eq loop2)

                        Set Variable: "isNumber" = true

                  End If

                  Set Variable: "loop2" = loop2+1

            End Loop

            If (isNumber=false)

                  Set Variable: "badInput" = true

            End If

            Set Variable: "loop1" = loop1+1

      End Loop

      If (badInput=true)

            Trace ("Not all numbers!")

      Else

            Trace ("All numbers!")

      End If

End On


That will take a string, run through it as few times as possible to make

sure its all numbers and then either print to the trace window Not all

numbers! or All numbers!.  For your uses just swap out those trace

statements with what you need. Enjoy!
