Set field value to yyyymm of date field in form

[Paul Heffner]

Hi! I want to set a rule that sets a field value based off a date field. I want the field value to be yyyymm (202105) based off the date a user enters.

I see you can do somwthing like {Timestamp[yyyy]} but that doesnt work for an internal field name

Hi,
There is unfortunately no such formatting option built in, but you can do it with some custom js.

Add this to your Custom JS:

function setCustomDateStr(){
    var d = spjs.utility.getDateFieldAsDateObject("YOUR_DATE_FIELD");
    var dStr = d.getFullYear() + String(d.getMonth() + 1).padStart(2,"0");
    setFieldValue("YOUR_TEXT_FIELD", dStr);
}

Now set up a rule to trigger on change on your date field, and in the field “Run these functions / evaluate these rules” add the function name setCustomDateStr.

Change YOUR_DATE_FIELD and YOUR_TEXT_FIELD to match your fields.

I am getting the error the objext doesnt support padStart

[Alexander Bautz]

I forgot padStart isn’t available in IE – try it like this instead:

function setCustomDateStr(){
    var d = spjs.utility.getDateFieldAsDateObject("YOUR_DATE_FIELD");
    var month = d.getMonth() + 1;
    if(month < 10){
        month = "0" + month;
    }
    var dStr = d.getFullYear() + month;
    setFieldValue("YOUR_TEXT_FIELD", dStr);
}

I’m trying to use this but, it is giving me an error. Here’s the code I’m using:

function setCustomDateStr(){
var d = spjs.utility.getDateFieldAsDateObject(“DateServicesProvided”);
var dStr = d.getFullYear() + String(d.getMonth() + 1).padStart(2,”0″);
setFieldValue(“YearMonth”, dStr);
}

When the date changes, I get an error that says the “TypeError: d.getFullYear is not a function”. If I click OK, the function works and the correct number is filled in. But how do I get rid of that error?

[Alexander Bautz]

Try adding an alert (or console.log) to see what the value for d is.

It might be that you need a little timeout to let the picker “finish” – try it like this:

function setCustomDateStr(){
    setTimeout(function(){
        var d = spjs.utility.getDateFieldAsDateObject("DateServicesProvided");
        var dStr = d.getFullYear() + String(d.getMonth() + 1).padStart(2,"0");
        setFieldValue("YearMonth", dStr);
    },100);
}
