Client script to validate start/end date fields

[nmcl]

We have 'end date validation' on our change request form, so that the end date has to be after the start date (logical).

I've copied this script over to a catalog client script but it's not working in the same way, it simply prompts regardless of the date entered.   Any ideas?

--- script ---

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

  if (isLoading || newValue == '') {

  return;

  }

  var end = g_form.getValue("loan_required_to");

  var start = g_form.getValue("loan_required_from");

  // skip if start or end is blank

  if (start == "" || end == "") {

  return

  }

  // get user's date time display format

  var format = g_user_date_time_format;

  var isEndBeforeStart = compareDates(start, format, end, format);

  // 1 (true) if start is greater than end

  // 0 if end is greater than start of if they are the same

  // -1 if either of the dates is in an invalid format

  if (isEndBeforeStart) {

  alert("End must be after start");

  }

}

Hi Nat,

I had done something similar,

Here is how i did it, hope it helps

var msg;

var dateFormat=g_user_date_time_format;

var task_start = g_form.getValue('start_date');

var task_end = g_form.getValue('end_date');

var flag=compareDates(task_start , dateFormat , task_end   , dateFormat);

if( flag== 1)

  {

  msg = 'Start date cannot be more that End date. ';

  alert(msg);

}

i have this as a starrt date validation routine

There is one for end date too

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

       if (isLoading || newValue == '') {

               return;

       }



       g_form.hideFieldMsg('start_date');

       var dtEndForm = g_form.getValue('end_date');

       var dtEnd = getDateFromFormat(dtEndForm,g_user_date_time_format);



       if (dtEndForm != '') {

               var dtStartForm = g_form.getValue('start_date');

               var dtStart = getDateFromFormat(dtStartForm,g_user_date_time_format);

               if (dtEnd < dtStart) {

                       g_form.showFieldMsg('start_date', 'Planned start date cannot be after end date', 'error');

               }

       }
