Hi,
Please find my code below.
I am calculating the date in Oninitilization event.
call function 'CONVERT_DATE_TO_INTERNAL'
  exporting
    date_external            = w_pd
  importing
    date_internal            = w_pdate
  exceptions
    date_external_is_invalid = 1
    others                   = 2.
lw_p = w_pdate .
call function 'DAY_IN_WEEK'
  exporting
    datum = lw_p
  importing
    wotnr = lw_day.
if lw_day eq 5.
  lw_day = 0.
elseif lw_day eq 6.
  lw_day = 1.
elseif lw_day eq 7.
  lw_day = 2.
else.
  lw_day = lw_day + 2.
endif.
lw_date = lw_p - lw_day.
lw_to = lw_date + 5.
In the layout i am passing the Variable to Javascript..
Script Begin...
var data1 = this.value;
var date = data1.split("/");
var month = date[0];
var day = date[1];
var year = date[2];
var a = year+""+month+""+day;
var dd = data1;
var fri = <%= lw_date.%>
var thu = <%= lw_to.%>
var lw_from_date = '<%= w_from_date.%>'
var lw_to_date = '<%= w_to_date.%>'
Script end...
This javascirpt will always trigger when an Button event is triggered..as per you submit button.this will work every time the page get refreshed.
Hope this is clear let me know if you have any concerns.
Thanks
