How to prevent a user from selecting a date in the past for date/time variably type??

[gnunez]

Hello all,

We have a couple of catalog items that use the date variable type and we want to restrict the user's from selecting a date in the past. Is this possible?

Also, we have Start Date and End Date on one our catalog items, does anyone know if its possible to restrict the end date to show dates past the selected start date?

Any suggestions are greatly appreciated!

Thanks,

Grace

For Portal only;

Add onChange client script on start date and add onChange client script on end date

Start

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue == '')
		return;
	
	// Date format
	var dateFormat = g_user_date_format.toUpperCase();
	
	// Make sure start date is valid
	if (!(new moment(newValue, dateFormat).isValid())) {
		alert('The date entered is not a valid fromat, please use the date selector or enter using the format: ' + dateFormat);
		g_form.setValue('start_date', '');
	}
	else {
		// Check that start is not in the past
		if (moment().diff(newValue, 'days') > 0) {
			alert('The start date must be on or after today.');
			g_form.setValue('start_date', '');
		}
	}
}

End

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

	// Date format
	var dateFormat = g_user_date_format.toUpperCase();

	// Make sure end date is valid
	if (!(new moment(newValue, dateFormat).isValid())) {
		alert('The date entered is not a valid fromat, please use the date selector or enter using the format: ' + dateFormat);
		g_form.setValue('start_date', '');
		g_form.setValue('end_date', '');
	}
	else {
		// Variables used
		var startStr = g_form.getValue('start_date');
		var startDate = new moment(startStr);

		// Check that end is not in the past
		 if (startDate.diff(g_form.getValue('end_date'), 'days') >= 0) {
			// The end date cannot be the same or less than the start date
			alert('The end date must occur after the start date.');
			g_form.setValue('end_date', '');
		}
	}
}

Thanks Mike this is helpful, but when testing I was still able to select dates in the past without getting an error message.

The only difference I noticed was when submitting both fields were highlighted with a red border

Hi,

Kindly use this code:

Suppose the  variable/field name is 'current_date' on the catalog item/form

---'OnChange' Client Script 

--field name : current_date

-Script :
function onChange(control, oldValue, newValue, isLoading)
{
if(isLoading)

{

 return;

}

//start the validation

if(newValue != '')

{
var ga = new GlideAjax('ConfirmDate');
ga.addParam('sysparm_name', 'chkCurrDate');
ga.addParam('sysparm_date',g_form.getValue('current_date'));
ga.getXML(NewParse);
}
function NewParse(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
if(answer == 'false'){
alert("Date selected is a past entry.");
g_form.setValue('current_date', ''); // Setting the variable as empty
}}}

----Script include  :-

---Name : ConfirmDate
--Client callable : true
-Script :

var ConfirmDate= Class.create();
ConfirmDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {
chkCurrDate : function() {

var start = this.getParameter('sysparm_date');
var currDay = gs.now();
if(start < currDay){
return false;
}
else
{ return true; } } });

Munender
