How to restrict start date to be selected as past date.

[VIKAS MISHRA]

I have created below mentioned onchange client script, this is working that  i am not able to select the past date but along with past date its not even allowing me to select the today's date also and giving me the same error. please suggest

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }

  var date1 = new Date(g_form.getValue('start_date'));
var date2 = new Date();
if(date1 <date2){
alert("Add future day");
g_form.clearValue('start_date');
}
   
}

Hello @VIKAS MISHRA ,

Please use the below OnChange Client script,

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

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

        return;

    }

    var currentDate = new Date();

    var currentDateStr = formatDate(currentDate, g_user_date_format);

    var currentDate = getDateFromFormat(currentDateStr, g_user_date_format);

    var startDate = getDateFromFormat(newValue, g_user_date_format);

    if (startDate < currentDate) {

g_form.ClearValue('start_date')

        g_form.showErrorBox('start_date',getMessage("Start date should be today or future date."));

return;

    }

}

Thank you

Hello @VIKAS MISHRA ,

Please use this script if you are using a Date (no time) field:

var startDate = getDateFromFormat(
		g_form.getValue('start_date'), g_user_date_format),
	today = new Date().setHours(0, 0, 0, 0);

if (startDate < today) {
	g_form.clearValue('start_date');
	g_form.showErrorBox('start_date', 'Start date cannot be in the past');
}

Use this if you are using a Date/Time field:

var startDate = getDateFromFormat(
		g_form.getValue('start_date'), g_user_date_time_format),
	now = new Date().getTime();

if (startDate < now) {
	g_form.clearValue('start_date');
	g_form.showErrorBox('start_date', 'Start date cannot be in the past');
}

Or create a UI Policy and UI Policy Action as shown below:

Hi @VIKAS MISHRA 

Not sure what the exact case is here, but did you try using a UI Policy to restrict the user from selecting a past date? UI Policies are low-code and easy to configure.
