The basic answer is AJAX, and jQuery provide AJAX tools. There is also support in web2py for some simple direct ajax operations. I would urge you not to use the CRUD forms; they are deprecated and not being maintained. In the documentation at the tip of the tree, you will find a warning about this. (There seem to be some hosting issues with getting the tip version displayed.) /dps > On Thursday, September 27, 2018 at 2:24:04 AM UTC+5:30, Dave S wrote: >> >> >> >> On Wednesday, September 26, 2018 at 10:43:31 AM UTC-7, Donald McClymont >> wrote: >>> >>> Hi Rahul >>> >>> You could just do this with Jquery as events that run when any of the 3 >>> fields are exited however I am not convinced that's really a great approach >>> - I haven't seen an example of doing this as part of the actual SQLFORM. >>> Another question would be do you really need to concatenate them as part of >>> your data entry?
