I have two fields effective and end date , the end date should be defaulted to one year upon selecting the effective date in client script in servicenow

Hi @HARSHA GOWDA R 

Have a look here, change the fields and try your hands

Something like this should work in a server side code, like BR

var gdt = new GlideDateTime(current.<effictive date field>);
current.end_date = gdt.addDays(365);;

Hi @HARSHA GOWDA R 

Create a Script Include

 and client script as below

Client Script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (!isLoading) {
        var effectiveDateField = 'effective_date';
        var endDateField = 'end_date';

        // Get the values of the effective date field
        var effectiveDate = g_form.getValue(effectiveDateField);

        // Check if the effective date is not empty
        if (effectiveDate) {
            // Call the server-side script to calculate one year later
            var ga = new GlideAjax('DateUtils');
            ga.addParam('sysparm_name', 'calculateOneYearLater');
            ga.addParam('sysparm_start_date', effectiveDate);
            ga.getXML(answerCallback);
        } else {
            g_form.setValue(endDateField, '');
        }
    }
}

function answerCallback(response) {
    if (response && response.responseText) {
        var endDate = response.responseText;
        var endDateField = 'end_date';

        // Set the calculated end date in the end date field
        g_form.setValue(endDateField, endDate);
    }
}

Script Include

var DateUtils = Class.create();
DateUtils.prototype = {
    initialize: function() {},

    // Function to calculate one year later from the given date
    calculateOneYearLater: function(startDate) {
        var gdtStartDate = new GlideDateTime(startDate);
        gdtStartDate.addYears(1);
        return gdtStartDate.getDisplayValue();
    },

    type: 'DateUtils'
};

 Please Mark it correct if your issue is resolved.

Thank You,

Sure, you can achieve this by using a client script in ServiceNow. Here's a sample code:

javascript
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//Get the effective date
var effectiveDate = g_form.getValue('effective_date');
if(effectiveDate != ''){
//Create a date object
var date = new GlideDateTime(effectiveDate);
//Add one year to the date
date.addYears(1);
//Set the end date
g_form.setValue('end_date', date.getDisplayValue());
}
}

Here are the steps to implement this:

1. Navigate to "Client Scripts" in ServiceNow.
2. Click on "New" to create a new client script.
3. Fill in the necessary fields:
- Name: Give a name to your client script.
- Table: Select the table where your fields are located.
- Type: Select "onChange".
- Field name: Select your "effective_date" field.
4. Paste the above code in the "Script" field.
5. Click on "Submit" to save your client script.
