HTMLB->Button Event CASE Dyn Nav problem

Hallo Milan,

Only been on the answer side in this forum, sometimes might make me a bit touchy. I see my share of questions per day where careful reading would definitely have saved the questions and the answers.

Yes, your question was written clear and concise. For me it just very difficult to always judge exactly what you know or don't. Especially when people only "silently" follow the forum over a long time.

I will in future "sticking to subjects I know" for all your questions, and refrain from shooting in the dark. Maybe not always a timely answer is a good answer. (I do try never to answer fluff, but then as writer I can not just my answers.)

At least, in my defence I can quote: "solving my problem". So ROI maybe not perfect, but still positive.

regards, brian

PS: I previously forgot to write it, but there is also the technique of setting the target page directly in the browser. You can fill the onClientClick with some JavaScript in the direction of "document.location.href = 'previous_page.htm';" (code not tested). This will directly load the previous_page.htm without first the server roundtrip.

Hallo Milan, (interesting name, English?)

Somehow we are just overlooking something. I quickly built a very small cut-and-paste example.

Create a new BSP application, and add into it three pages called page1.htm, page2.htm and page3.htm. The source is below. (Note all three has the same event handler:).

<b><u>onInputProcessing for all three pages</u></b>
DATA: event TYPE REF TO if_htmlb_data.
event = cl_htmlb_manager=>get_event_ex( request ).
IF event IS NOT INITIAL AND event->event_name = 'button'.
  navigation->goto_page( event->event_server_name ).
ENDIF.

<b><u>page1.htm</u></b>
<%@page language="abap" otrTrim="true"%>
<%@extension name="htmlb" prefix="htmlb"%>
<htmlb:content design="design2003">
  <htmlb:page>
    <htmlb:form>
      <htmlb:button       text          = "Page 2"
                          design        = "NEXT"
                          onClick       = "page2.htm" />
    </htmlb:form>
  </htmlb:page>
</htmlb:content>

<b><u>page2.htm</u></b>
<%@page language="abap" otrTrim="true"%>
<%@extension name="htmlb" prefix="htmlb"%>
<htmlb:content design="design2003">
  <htmlb:page>
    <htmlb:form>
      <htmlb:button       text          = "Page 1"
                          design        = "PREVIOUS"
                          onClick       = "page1.htm" />
      <htmlb:button       text          = "Page 3"
                          design        = "NEXT"
                          onClick       = "page3.htm" />
    </htmlb:form>
  </htmlb:page>
</htmlb:content>

<b><u>page3.htm</u></b>
<%@page language="abap" otrTrim="true"%>
<%@extension name="htmlb" prefix="htmlb"%>
<htmlb:content design="design2003">
  <htmlb:page>
    <htmlb:form>
      <htmlb:button       text          = "Page 2"
                          design        = "PREVIOUS"
                          onClick       = "page2.htm" />
    </htmlb:form>
  </htmlb:page>
</htmlb:content>

I highly recommend to run this in design2003. You will love that PREVIOUS/NEXT design on the buttons. If this example is not working for you, there are a few other things to be checked. But first try this.

Excellent English!

Hope you hang around!

Hi Milan,

You must not think of differences between the libraries, but more extensions of. Once we had to do new work, we did not want to change the existing HTMLB library, so we created the XHTMLB library. And then, when we did the design2003, we added again the new controls into the PHTMLB library. These are just add-on libraries.

Unfortunately documentation was do only very late for the PHTMLB lib. If I am not mistaken, maybe SP40+. Until then, there is only the BSP example SBSPEXT_PHTMLB, direct questions or some reverse engineering.
