More specifically, the 4D concept of object methods associated with input field and variables. I would like to call a 4D routine to scan the entry of a text area and verify its validity without 'posting'. Is this possible?
Bill,
Unfortunately the browser only knows html, javascript, css and a few other things so if you want the power of 4d you will have to do that on the server.
If you want to do client side checking or validation of an input field without posting back to the server, you will need to use javascript. If you use server side validation you can either call 4d method(s) or more appropriately write an Active4d method(s) that does the validation. I would highly recommend doing the server-side validation with A4D methods.
