Adobe JavaScript- Check a box if the date entered is older than 365 days

Question

I am trying to create either a Validation Script or a Javascript Action in Adobe.

I need to check a box called CheckBox2 is the Date entered in DORMANT is greater than 1 year old from Today's date.

So if Date entered is 06/02/2021 then the box would be checked.

I have googled so many things and not found an answer that works.
Any help would be great.

Thank you

Answer 1

// Get the value of the DORMANT field
var dormantDateStr = this.getField("DORMANT").value;

// Parse the date entered in the DORMANT field
var dormantDate = util.scand("mm/dd/yyyy", dormantDateStr); 
//ensure the date format here matches the date in your field DORMANT

// Get today's date
var today = new Date();

// Calculate the date one year ago from today
var oneYearAgo = new Date();
oneYearAgo.setFullYear(today.getFullYear() - 1); 


// Check if the dormant date is more than one year ago
if (dormantDate < oneYearAgo) {
    // Check the CheckBox2
    this.getField("CheckBox2").checkThisBox(0, true);
} else {
    // Uncheck the CheckBox2 if the condition is not met
    this.getField("CheckBox2").checkThisBox(0, false);
}

getFullYear

Also, you could add this as a JS script in Adobe instead of a validation script, can be triggered when DORMANT is filled and loses focus etc. Adobe Acrobat > Tools > JavaScript > Document JavaScripts > Add
