Dynamic actions in tabular forms

Question

Hi,
i have 4 columns in tabular forms.
emp_code emp_name emp_position emp_status
whenever a user enter the emp_code
the emp_name,emp_position and emp_status should be automatically displayed.
i try to use dynamic actions to populate the emp_name , emp_position, emp_status.
but i cannot identify which columns / item to use since its a tabular forms.
can anyone help ?
thanks

Answer 1

here's what you can do for your situation
<li>Create an AJAX Callback process(PLSQL type) in your page that is similar to
DECLARE
  lc_result XMLTYPE;
BEGIN
   SELECT XMLELEMENT("COL"
                                 ,XMLELEMENT("COL1", wwv_flow.g_x01)
                                 ,XMLELEMENT("COL2", LPAD(wwv_flow.g_x01,10,'0'))
                                 ,XMLELEMENT("COL3", RPAD(wwv_flow.g_x01,10,'#'))
                                 ,XMLELEMENT("COL4", 'blah blah')
                               ) RESULT
  INTO lc_result
  FROM DUAL;
    OWA_UTIL.MIME_HEADER('text/xml', false);
    htp.p('Cache-Control: no-cache');
    htp.p('Pragma: no-cache');
    OWA_UTIL.HTTP_HEADER_CLOSE();
    htp.p(lc_result.getstringval());
END;This returns an XML with the rows data. I have just used some simple processing of the input data in this case, but you can modify it for your need
<li>Then have a Dynamic Action that is triggered on change of the f01 input field
//value of triggered item
val = $(this.triggeringElement).val();
//Call Ajax Callback process
var a = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=FETCH_ROW',$v('pFlowStepId'));
a.addParam('x01',val);
X = a.get('XML');
//Obtain data from returned XML
col2 = $(X).find('COL2').text() ;
col3 = $(X).find('COL3').text() ;
col4 = $(X).find('COL4').text() ;
//Set items
this_row = $(this.triggeringElement).parents('tr:first');
this_row.find('input[name=f02]').val(col2);
this_row.find('input[name=f03]').val(col3);
this_row.find('input[name=f04]').val(col4);This sends the f01 field(triggering source) to the PLSQL that returns the data in XML format for 3 other columns and sets those columns.
Hope that answers your question.
