toLocaleDateString is not working in server side script

[aikotoba]

Hi
We need to convert a date to Japanese calendar.
On the client side, dt.toLocaleDateString('ja-JP-u-ca-japanese',{era: 'long'}) works and converts the date to the Japanese calendar without any problem, but
However, the business rule does not work well.
Doesn't it work on the server side?
Please help.

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading)
        return;

    if (newValue == "") {
        g_form.clearValue("end_date_japanese");
        return;
    }
	;
	var dt = new Date(newValue);
	var japaneseDate = dt.toLocaleDateString('ja-JP-u-ca-japanese',{era: 'long'})
	g_form.setValue("end_date_japanese",japaneseDate);
}

Hi @aikotoba ,

You will need to use this script instead of toLocaleDateString to get the same functionality as per your requirement, just change the code as per your req:

Mark my answer correct & Helpful, if Applicable.

Can you add the script you use? The current script you added is a client side script. if you are using this in a business rule it will not work.

I wrote the following, but the invalid date will be set value.

var date = current.date_field;
var dt = new Date(date);

var japaneseDate = dt.toLocaleDateString('ja-JP-u-ca-japanese',{era: 'long'});
current.japanese_date = japaneseDate;

what kind of field is "current.japanese_date"? Are you sure the variable japaneseDate has the correct value? and correct value type expected by the current.japanese_date field
