I have a standard live view form with two fields whose values are dependent upon each other, meaning a change in one field updates the other. I therefore need to determine which of the fields the user has actually entered data in. Is there any problem in using the “_target” value passed to handle_event?
I ask because generally any value that starts with an underscore usually means it is an implementation detail and shouldn’t be relied on as it could change in the future.
[For info I can’t use get_change on the changeset as the user may have entered values in both fields so I need to know which field actually triggered the handle_event].
