Difference in submiting form using JS(CLient Side) and ABAP(server side).

[former_member184111]

Hi All,

We are implementing OCI . When i submit the for using below code:

<htmlb:button         id            = "submit"
                            text          = "Transfer To Shopping Cart"
                            tooltip       = "Transfer catalog to shopping cart"
                             o n C l i e n t C l i c k   =   " g o b a c k ( ) ; "   / > 
<scrapt typw="texa/javascaipt">
fu   n c t i o n   g o  b a   c k ( )
{

var r e t _ U R L   =   " < % =   H O O K _ U R L   %> " ; 
d oc u m e n t . f i n a l . a c t i o n   =   r e t _ U R L ;
d o c u m e n t . f i n a l . m e t h o d   =   " P O S T " ;
d o c u m e n t . f i n a l . s u b m i t ( ) ;
}
</script>

the form is sumbited properly whereas if i use :

<htmlb:button         id            = "submit"
                            text          = "Transfer To Shopping Cart"
                            tooltip       = "Transfer catalog to shopping cart"
                            o n C l i c k   =   "transfer "   / > 

in OnInputProcessing:
when 'transfer'.
navigation->goto_page( hook_url ).

i get the error:

BSP Exception: The side exit http://sapupd.xxxxx.com:8002/sap (cz1TSUQlM2FBTk9OJTNhc2FwdXBkX1NSTV8wMiUzYXJUaHBOdE0yYlVsVnQ5NzAtS0wwdmFOUWdnTWo3WHpHY01YS2NITmMtQVRU) / bc/gui/sap/its/bbpsc02 /? OkCode = ~ ~ ADDI & target = _top & caller = ~ ~ Ctlg & SAPSessionCmd = open & ~ sap syscmd = NOCOOKIE & client = ~ ~ 200 & lan is for the page final.htm not defined.

What is the problem in submiting form at server side?

Thanks,

Hi Anubhav,

what should I say, I don't know the parameters either...

But you can use a http logger to monitor the http request that is transferred in your variant submitting the form by JavaScript. Maybe you can find out the missing parameters.

Hi,

Here is a sample code to submit a form content to a page with a round-trip to server (a little adapted to your problem).

Note that l_page is declared as a type STRING page attribute.

Layout:

<%@page language="abap"%>
<%@extension name="htmlb" prefix="htmlb"%>

<% if l_page is initial. %>

... put here your current BSP page layout ...

<% else. %>
<%=l_page%>
<% endif. %>

OnInputProcessing:

CHECK event_id = cl_htmlb_manager=>event_id.

DATA: my_nav TYPE REF TO cl_bsp_navigation,
      t_fields TYPE tihttpnvp,
      l_field  TYPE ihttpnvp.
...
WHEN 'transfert'.
request->get_form_fields( CHANGING fields = t_fields ).

LOOP AT t_fields INTO l_field WHERE name NE 'oninputprocessing' AND name NP '*htmlb*'.
  navigation->set_parameter( name  = l_field-name
                             value = l_field-value ).
ENDLOOP.

navigation->use_auto_submit_form( ).

navigation->encode_parameters( bspr_yes ).

navigation->goto_page( hook_url ).

my_nav ?= navigation.

CALL METHOD my_nav->construct_url
  IMPORTING
    page = l_page.

my_nav->reset( ).
RETURN.
...

Hi All,

I am extremly sorry for so late response.

I tried with the code provided by Tanguy,but with this code the form is not submited at all.

value of l_page is

<h tml><bod y onL oad="Java Script: docume nt.f.submit();"><for m id="f" na e="f" met hod="POST" a ction="h ttp: //sapupd.xxxxx.com:8002/sap(cz1TSUQlM2FBTk9OJTNhc2FwdXBkX1NSTV8wMiUzYW5haXRyamM0ZFdjNjdkQ3YzT1FuQ2tXYmh4MHhiZlVIejVtcC1WR3MtQVRU)/bc/gui /s ap/its/ bbpsc02

Please guide me on this.

Hi Anubhav,

do you want to provide some additional parameters to your ITS-Application?

In case of submitting a html-form by JavaScript , the values of the parameters are added automatically to the request.

In case of using navigation->goto_page( ), you have to add them by

navigation->set_parameter( name='parameter_name' value = parameter_value ).

Maybe that's the problem?

Hi Cornelia,

I can add parameters to the URL as you suggested and in SPRO also parameters can be added to the url....but i dont know what parameters to add so that the page is submited properly using server event.

Thanks,

Hi Anubhav,

in general it is possible to call an external URL by navigation->goto_page( ).

Try with a simple URL like navigation->goto_page( 'http://sap.com' ). If this works, maybe you have a problem with your ITS-Application. The URL you provided seems to be truncated. Did you check wether you can call it standalone directly in your browser?

Best regards,

Hi Cornelia,

The full URL is:

And yes , it works with other URLs .When i try to call this URL directly in browser it shows done but with errors and teh IE remains blank.

Thanks,

Anubhav.

what is the value in the hook_url .?

navigation->goto_page( hook_url ).

ideally it should work. instead of hook_url give the page ex

navigation->goto_page( 'main.htm' ).

[former_member184111]

Hi Vijay,

Value of hook_url is:

http://sapupd.xxxxx.com:8002/sap(cz1TSUQlM2FBTk9OJTNhc2FwdXBkX1NSTV8wMiUzYXJUaHBOdE51YndkY0NjNXlOdlNjNkdXbUNBTWo3VURHdDhXZm9NNzktQVRU)/bc/gui/sap/its/bbpsc02/?~OkCode=ADDI&~Target=_top&~Caller=CTLG&~SAPSessionCmd=open&~sap-syscmd=NOCOOKIE&~client=200&~lan

it is the url of an ITS application,to which this form is submited.

Its working fine with other URLs.

Thanks,

Anubhav.
