form validation - Not equal to....

[youssefaoun]

Hello,

Is it possible to make negative validation?

example: If the field is equal to value ('Choose Please'), we return an error ?
Among the function we have

 $javascript->addToValidateBinaryDependency(...); 
  

Do we have any that perform such a test?
(I didn't find any)
Is there any other possibilities?

Regards,

Yes, just make the key of 'Choose Please' blank ("") and then make the field required. That way if the user leaves it at 'Choose Please' it will be blank and the required field javascript will give you the error you are looking for.
