Hi try below code

function onChangeDate() {
var dateField = g_form.getValue('your_date_field'); // Replace 'your_date_field' with the actual field name

// Parse the date string to a JavaScript Date object
var dateObject = new Date(dateField);

// Get the month in three-letter abbreviation
var monthAbbreviation = getMonthAbbreviation(dateObject.getMonth());

// Format the date as DD/Mon/YYYY
var formattedDate = dateObject.getDate() + '/' + monthAbbreviation + '/' + dateObject.getFullYear();

// Set the formatted date back to the field
g_form.setValue('your_date_field', formattedDate);
}

function getMonthAbbreviation(monthIndex) {
var monthNames = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
return monthNames[monthIndex];
}
