Retrieve value from input text field within a model view controller ( MVC) BSP
Below is the basic code for allowing users to input text onto a html page and retrieve what they have entered using HTMLB and MVC techniques.
Display input field and retrieve value entered
View Layout
------
This is the HTMLB code to display an input field. In this example it uses
ld_fieldid to store and display a value in the field, you will need to create
this within the attributes section of the view.
<htmlb:inputField id = "fieldId"
invalid = "true"
value = "<%=ld_fieldid%>"
required = "true"/>
DO_REQUEST method (within controller class)
-----------------
DATA: data_input TYPE REF TO cl_htmlb_inputfield,
ld_fieldid TYPE string.
data_input ?= cl_htmlb_manager=>get_data(
request = runtime->server->request
name = 'inputfield'
id = 'fieldId' ).
IF data_input IS NOT INITIAL.
ld_fieldid = data_input->value.
ENDIF.
Display dropdown list field and retrieve value entered
Layout
------
The code below is HTMLB.
<htmlb:dropdownListBox id = "myDropdownListDay"
tooltip = "Quick info for myDropdownListBox">
<htmlb:listBoxItem key = "<%=dropday%>" value = "<%=dropday%>"/>
<% data: ld_index type i,
ld_datum type sy-datum.
ld_index = 0.
do.
ld_index = ld_index + 1. %>
<htmlb:listBoxItem key = "<%=ld_index%>"
value = "<%=ld_index%>"/>
<% if ld_index = 31.
exit.
endif.
enddo. %>
</htmlb:dropdownListBox>
DO_REQUEST method (within controller class)
-----------------
DATA: data TYPE REF TO cl_htmlb_dropdownlistbox,
ld_dropyear TYPE string.
data ?= cl_htmlb_manager=>get_data( request = runtime->server->request
name = 'dropdownlistbox'
id = 'mydropdownListDay' ).
IF data IS NOT INITIAL.
ld_dropday = data->selection.
ENDIF.
