You can incorporate this validation feature into any existing form, any number of times.
The form elements must be named consistently so the script can work with them.
s
as q + the number of the question + a, b, c, etc. In this case, the form elements are named:
q1a
To use the validation, call rankem(a,b) where the parameters are the question number and its length.
In this case, the form handler calls the function twice:
rankem(1,4);
Each call will generate a separate alert if there's anything amiss. The global "badrank" variable
is a status flag so the main form handler knows if it's allowed to submit(). Note that this demo
doesn't acutally do a submit(); instead it just displays a message.
