Datarefreshment after ging "back"
Hi Dave,
thanks for this hint, it could be a wonderful idea but i dont think, this
will work.
Reading the value onload will give the default value of this field. The
correct (previously sent) value will be filled by the browser after loading
the page and before the user will be able to work with the page (perhaps
even before he can see it).
So the problem is more to know when (not if) it happened or could have
happened.
I am doing something with those values, but after or while loading the page,
all fields have their default values, the checkboxes are all unchecked.
After loading is completed, the browser fills the values with those, having
been sent. But nothing tells me, when this happened so i can start reading
the values (which is the first possible moment, because the values before
are all default)
sorry for not beeing that clear,
greetings,
dtr.
