Script Include Date Validation

[Kamva]

Hi Developers,

I have a script include to validate dates (start date and end date) on a catalog item. The end date should be bigger than (or the date after) the start date, however, if my end date is on month after my start date (eg 13-06-2023) but the date is smaller than the date of my start date (eg 29-05-2023). The script deems the end date smaller than my start date. Please check the scripts and the attachments below and help me fix the problem.

Script Include:

var EndDate = Class.create();
EndDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	
	endDate: function(){
		//GETTING DATES FROM THE UI
		var endDate = this.getParameter('sysparm_end_date');
		var startDate = this.getParameter('sysparm_start_date');
		
		//GETTING TODAYS DATE
		var _gdt = new GlideDateTime();
		var gdt = _gdt.getByFormat('dd-MM-yyyy');
		
		if (endDate == startDate){
			return 'Delegate should be created at least for 1 day';
		}else if (endDate < startDate){
			return 'End date should be after the start date selected';
		}
		
		gdt.addDaysUTC(30); //Highest possible date
		if(endDate < gdt){
			return 'Delegate can be created for 30 days at max';
		}
		return 'valid';
	},
	
    type: 'EndDate'
});

Catalog Client Script:

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

   //Type appropriate comment here, and begin script below	
	var gaStartDate = new GlideAjax('StartDate');
	gaStartDate.addParam('sysparm_name', 'startDate');
	gaStartDate.addParam('sysparm_start_date', g_form.getValue('starts'));
	gaStartDate.getXML(startDateParse);
	
	function startDateParse(response){
		var ans = response.responseXML.documentElement.getAttribute('answer');
		if (ans != 'valid'){
			g_form.addErrorMessage(ans);
			g_form.clearValue('starts');
		}
	}
}

@Kamva 

so if start date is 29th May then end date should be after it

I didn't get the extra validation

[Kamva]

@Ankur Bawiskar it should be any date after 29 of May

@Kamva 

simply use this in onChange client script of end date

something like this and enhance it furter

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

	if(g_form.getValue('starts') != '' && newValue){
		var start = new Date(g_form.getValue('starts')).getTime();
		var end = new Date(newValue).getTime();
		if(end < start){
			var message = 'Please give valid start and end dates';
			g_form.showErrorBox('ends', message);
		}

	}
}

Hello @Kamva ,

In the Catalog Client Script, I don't see any parameter for end date. GlideAjax has only Start date parameter passed.

   //Type appropriate comment here, and begin script below

var gaStartDate = new GlideAjax('StartDate');

gaStartDate.addParam('sysparm_name', 'startDate');

gaStartDate.addParam('sysparm_start_date', g_form.getValue('starts'));

//Parameter is missing for End Date

gaStartDate.getXML(startDateParse);
