Read field value from another page

Question

Hallo,
I have PAGE1.HTM (with MVC) with 2 input fields (country and state). For field STATE there´s a F4-button which calls PAGE2.HTM (page with logic) and in order to display the correct information for states I need to get the value in field country.
I cannot send the value from page1.htm because the code is client-side for F4 (specially if it changes) and I cannot use
var = document.getElementById("country");
in page2.htm because it´s Javascript code inside ABAP code, which is not allowed (I think).
Does somebody have an idea on how to collect that value or if I can use Javascript code in the event OnInitialization ??
Thanks a lot

Hi,
that´s something I do when the content of the view is created and works Ok. The values of that content come from the data bank. The problem is when the user enters a new value and does not saves it !! in this case, the new value is not transmited to PAGE2.HTM because now we´re on client side.
This is the code that creates the input field:
      tag_if  = cl_htmlb_inputfield=>factory( id = s_id
                                             value = fieldname
                                             visible = isvisible
                                             disabled = isdisabled
                                             isappendunit = 'True'
                                             showhelp = dfies-f4availabl
                                             dovalidate = 'TRUE'
                                             onvaluehelp = openf4code ).
and as far as I know, input field supports no event.
