Transfert parameters from HTM to HTM in one BSP

Question

Dear all,
In a preceding post, I asked to open an HTM from another in the same BSP.
The answer was
<htmlb:button id            = "DEFS"
                           text       = "Button Text"
                           onClientClick = "javascript:window.open ('secondpage.htm', '_blank', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=1,width=800,height=550,left = 200,top = 100');" />
and it works !
I have an additional question to this : I need to transfer some parameters from the first HTM to the second.
I added     
navigation->set_parameter( name  = 'preq_no' value = preq_no ).
"preq_no" is declared in page attributes of the 2 HTM and declared as automatic.
If I add navigation->goto_page("second_page.htm"), the parameter is transmitted but the system opens the second page in a new window.
So I have 2 pages with the same layout (one opened with goto_page and one opened with windows.open) and it is not possible.
Could someone help me ? I hope I was clear.
thanks
Véronique

Answer 1

from the first page define a button.
<htmlb:button id = "DEFS"
text = "Button Text"
onClientClick = "javascript:window.open ('secondpage.htm?<b>param=my_param</b>', '_blank', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=1,width=800,height=550,left = 200,top = 100');" />
in the second page on the DO_INIT or ONINITILISATION event.
data: lv_val type string/.
lv_val = request->get_form_field( name  = 'param1' ).
lv_val will have the value of your parameter..
you can pass multiple parameters in the header like
onClientClick = "javascript:window.open ('secondpage.htm?<b>param1=my_param&param2=my_param2&param3=my_param3</b>', '_blank', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=1,width=800,height=550,left = 200,top = 100');" />
