Generate HTMLB Code

[former_member184313]

Hi Folks

I have a strange question: How do I generate HTMLB Code?

<htmlb:textView text   = "<%= model->get_include( ) %>"
                        encode = "true" />

The Model Methode is implemented like this:

 
method GET_INCLUDE .
r_incl = '<%@ include file = "sel_sessio.htm" %>'.
endmethod.

This doesn't work, because the output of model->get_include( ) is not encoded as HTMLB. How can I do this?

Thanks for your help

Regards

Daniel

hi

can you elaborate your question, wether you want it to act as link or what.

Hi,

you cannot encode anything in HTMLB, but you could encode text in HTML format. There are some helpful methods for this in CL_HTTP_UTILITY (escape_html etc.).

But you don't have to encode the return values of your method I think. The htmlb:textView can handle any HTML Tag. You could for example write

<htmlb:textView text   = "<b>some bold text</b>" /> 

and the HTML inside the text attribute would be recognized and rendered as HTML.

hi,

Sorry, my question wasn't clear. Well, no link. I'd like to dynamically attach includes to a view. The function get_include( ) would be inside a Loop. There will be about 50 includes, that's why I cant use sub-controllers.

Unfortunately, this doesn't work, but is exactly what I need to do:

<%
loop at model->itab into ls_itab.
%>
<%@ include file = "<%= ls_itab-include_name %>" %>
<%
endloop.
%>

Thanks for your help.

Cheers

Daniel

Thanks for your Reply Daniel.

Is there a possible way to do the include with html?

Thanks

You could do something like this (not yet testet):

METHOD get_include.
  FIELD-SYMBOLS <source> LIKE LINE OF lt_typesource.
  DATA: lo_page    TYPE REF TO cl_o2_api_pages,
        ls_pagekey TYPE O2PAGKEY,
        lt_source  TYPE o2pageline_table.
  ls_pagekey-applname = 'ZAPPL'.
  ls_pagekey-pagekey  = 'a.htm'.
  CREATE OBJECT lo_page EXPORTING p_pagekey    = ls_pagekey
                                  p_create_new = ' '.
  CALL METHOD lo_page->reload( ).
  CALL METHOD lo_page->get_page( IMPORTING p_content = lt_source ).
  LOOP AT lt_source ASSIGNING <source>.
    CONCATENATE p_return <source>-line INTO p_return.
  ENDLOOP.

ENDMETHOD.

But this only works with pure html code in include.

Really, why not use sub-controllers. Your includes will be expanded in line, creating a very large class method. This single class method could very likely exceed the ABAP runtime limits.

<a href="/people/brian.mckellar/blog/2005/04/25/bsp-programming-gen-branchoffset-limit-reached Programming: GEN BRANCHOFFSET LIMIT REACHED</a>

If I had to do this, I would create 50 Views, but only one Controller. You can create your call to your controller with:

<% loop at model->itab assigning <wa_itab>. %>
 <bsp:call url="my_controller.do" comp_id = "view">
  <bsp:parameter name="view" value="<%= <wa_itab>-view_name %>"/>
 </bsp:call>
<% endloop. %>

Then in your single controller, you can call the proper view dynamically.
