How to make end date auto populate to a year after based on start date?

Nur1 · ‎05-18-2022

Hi Community,

For example, when I select 19-May-2022 in start date, the end date should auto populate to 19-May-2023.

How can I achieve this ? Kindly, please help.

Start and End Date is using Date type. not Date/Time.

Script Include:

var StartEndDate = Class.create();
CIMBStartEndDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    calculateDate: function() {

        var date = this.getParameter('sysparm_date');
        var year = 1;
        var gdt = new GlideDate(date);
        gdt.addYearsUTC(year);
        return gdt.getNowDate();
    },

    type: 'StartEndDate'
});

Client Script:

OnChange Start Date

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
	var ga = new GlideAjax('StartEndDate');
    ga.addParam('sysparm_name', "calculateDate");
    ga.addParam('sysparm_date', g_form.getDisplayValue('start_date')); // give here date variable name
    ga.getXMLAnswer(function(answer){
        if(answer != ''){
            g_form.setDisplayValue('end_date', answer); // give proper variable name here
        }
    });

   //Type appropriate comment here, and begin script below
   
}

I've tried this code but it's not working.

try this

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

	if(oldValue != newValue){
		var dateMS = getDateFromFormat(newValue, g_user_date_format);
		dateMS += 365 * 24 * 60 * 60 * 1000; // 365 days means 1 year
		var newDT = new Date();
		newDT.setTime(dateMS);
		g_form.setValue('end_date', formatDate(newDT, g_user_date_format));
	}
	//Type appropriate comment here, and begin script below

}

Hi @Nur

There were a few rectifications in your scripts. Please check the updated scripts below:

Client Script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
	var ga = new GlideAjax('StartEndDate');
    ga.addParam('sysparm_name', "calculateDate");
    ga.addParam('sysparm_date', newValue); // give here date variable name
    ga.getXMLAnswer(function(answer){
        if(answer != ''){
			//alert(answer);
            g_form.setValue('u_end_date', answer); // give proper variable name here
        }
    });

   //Type appropriate comment here, and begin script below
   
}

Client Script Screenshot:

Script Include:

var StartEndDate = Class.create();
StartEndDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    calculateDate: function() {

        var date = this.getParameter('sysparm_date') + ' 00:00:00';
		gs.info('[DEBUG] Date recieved: ' + date);
        var year = 1;
        var gdt = new GlideDateTime(date);
        gdt.addYearsUTC(year);
		gs.info('[DEBUG] Returning Date: ' + gdt);
        return gdt.getDate();
    },

    type: 'StartEndDate'
});
