How to work with date fields

[Wim Stevens]

We upgraded to modern dffs. There is Javascript code that reads a date/time field, adds some hours to it and stores the result in another field.
The old Javascript was not upgraded automatically.

I tried
x = getFieldValue(“InfoSecuritySetDate”);
x.setHours(x.getHours() + maxDelayHours);
setFieldValue(“Due_x0020_Date”, x);

This does not work because x is a String and not a Date object.
Question: how to retrieve the Date object that corresponds to InfoSecuritySetDate ? I have no idea what regional settings are used by the user. I cannot make assumptions about the regional settings of the Sharepoint site

Remark 1: the functions getFieldValue and setFieldValue are not documented in the user guide. I have found the functions via AI. Maybe there are other functions available that could be used.

Thanks

The only missing piece here is to specify the format of the value returned by the getFieldValue call – if you write it like this it gives you a proper date object:

x = getFieldValue("InfoSecuritySetDate", "object");

Excellent. This is what I needed.
Have I missed it in the documentation ?

This is currently not documented but the next version of Modern DFFS will have an autocomplete / info text when you start typing in the Custom JS textarea to show the different options available.
