Client side validation?

Client side validation?

Is it possible to perform a client side validation using built in functions? Example:
When a user fills in a form, use the built in function "EmailAddressVadliate" to check to see if the user's email address is valid, then display a message next to the input box as the user types in the values.

If this is not possible then, how do you return a "feedback" message WITHOUT wiping out the user's inputted values?

 Hi Robert,


Attached you have your OML with the input validation implemented as it is recommended by OutSystems. It is a server side validation, but it will work like you describe above.


You can find a tutorial about this in the Form Validations lesson of the Developer Course I. More detailed documentation is also available in Service Studio's online help.
