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.
