Data validaition

[venkatesh tadip]

Hi Team,

I have a requirement that i want to validate start date is greater that end date, then i need to show an alert message and it should validate all time formats like 12 hour and 24 hour. i want to achieve this in on submit client script.

Please let me know your suggestions on this

Thanks in advance.

Hi @venkatesh tadip ,

• Compare Start Date and End Date fields (likely of type Date/Time).

• Ensure all time formats are correctly interpreted.

• Show an alert and prevent submission if the condition fails.

function onSubmit() {
var startDateStr = g_form.getValue('start_date'); // Replace with your actual field name
var endDateStr = g_form.getValue('end_date'); // Replace with your actual field name

if (!startDateStr || !endDateStr) {
return true;   // Allow form submission if either date is not set
}

var startDate = new Date(startDateStr);
var endDate = new Date(endDateStr);

if (startDate > endDate) {
alert('Start Date must be less than or equal to End Date.');
return false;
}

Please mark it as helpful, if the solution is fine.

return true;
}

@venkatesh tadip 

you can use this if both are date/time type fields

function onSubmit(){
	var start = g_form.getValue('start_date');
	var end = g_form.getValue('end_date');
	var startDt = new Date(getDateFromFormat(start, g_user_date_time_format)).getTime();
	var endDt = new Date(getDateFromFormat(end, g_user_date_time_format)).getTime();
	if(endDt < startDt){
		alert('End date should be after Start Date');
		return false;
	}
}

Hello @venkatesh tadip ,

You can do that via a UI Policy. Please see the example below. Just replace the names of your start and end date fields accordingly.

function onCondition() {
	g_form.clearValue('work_end');
	g_form.showErrorBox('work_end', 'End date must be after start date');
}

Regards,

Robert
