Invalidate navigation

Question

Hi,
Situation:
In our BSP framework to each generated page we add a piece of javascript wich will check the input value on specified inputfields.
If the user fills in an exceptional amount we generate a popup (GetVBMessageBox) which warns him/her about the exceptional value. This works fine.
Problem:
When the user fills in an exceptional high value and doesn't leave the field (so the onChange event is not triggered) but presses the page-down key on the TableView the server navigates to the next page.
Then when the next page is displayed the popup is generated on the wrong page.
Question:
Is there a way to invalidate the navigation?
navigation->invalidate( )?

Answer 1

if you want to capture the user clicking navigate button in the table view on the server side you can use the following code in oninputprocessing
data: table           type ref to cl_htmlb_tableview .
data: tv_data type ref to cl_htmlb_event_tableview.
data: event type ref to cl_htmlb_event.
event = cl_htmlb_manager=>get_event( runtime->server->request ).
table ?= cl_htmlb_manager=>get_data( request = request
                                           name    = 'tableView'
                                           id      = 'tv1' ).
if table is not initial .
  tv_data = table->data .
endif .
if not tv_data is initial .
if tv_data->event_type = 'navigate' .
if tv_data->navigationtype = 'pageDown' .
**do something.
elseif tv_data->navigationtype = 'pageUp' .
** do something .
endif .
endif .
endif .
if you want to capture it on the client side, view the soruce of the page to identify the id for the button and write a javascript for onclick event of the button
