How do I populate a date depending on what is selected in a drop down?

[hpdouet84]

I have 1 field titled "Today" that populates the current date.  Then I have a drop-down field titled "Release Date" with the following selections: 14 Days, 180 Days, and Permanent.  I am trying to change the "Release Date" field into a calculated date using the "Today" field depending on what is selected in the drop-down list.  Example: If the "Today" field reads 01/18/2016 and the user selects "14 Days" from the drop-down list as the "Release Date" then I want the text to show as "02/01/2016", which is 14 days from today's date, instead of showing as "14 Days". What script should I use?

If you want the date calculated, you will need to perform the calculation using custom JavaScript for the calculation.

Have you looked for scripts about adding # days to a given date?

The Acrobat JavaScript API Reference Manual has examples of date calculations. Use Date Objects

I would rather use JavaScript's getDate and setDate options for manipulating days.

I'm new to this and have been reading so many discussions and verbiage on this that I am confusing myself more than anything.  This is the current custom calculation script I have:

(function () {

    // Get date from field
    var v = getField("Today").value;

    if (v) {

        // Convert string to date
        var d = util.scand('mm/dd/yyyy', v);

        // Add 14 days
        d.setDate(d.getDate() + 14);
        // Set value of this field to the new date
        event.value = util.printd("mm/dd/yyyy", d);

    } else {

        // Blank field if no date entered
        event.value = "";
    }
})();(function () {

    // Get date from field
    var v = getField("Today").value;

    if (v) {

        // Convert string to date
        var d = util.scand('mm/dd/yyyy', v);

        // Add 180 days
        d.setDate(d.getDate() + 180);
        // Set value of this field to the new date
        event.value = util.printd("mm/dd/yyyy", d);

    } else {

        // Blank field if no date entered
        event.value = "";
    }
})();

The issue I'm having is no matter which option is selected from the drop-down list, it still populates the date as Today + 180 days.

I see nothing that checks the dropdown selection for the number of days to use in the calculation.

Well then I guess I need to research scripts more on how to make that happen because this is Greek to me.  Thanks for your help.

Document level Scripts:

// common functions for processing PDF forms;

// get a field object with error processing;
function GetField(cName) {
// return field object or null if not found;
var oField = this.getField(cName);
if(oField == null) {
app.alert("Error accessing field named " + cName, 0,1);
}
return oField;
} // end GetField function;

// scan date string with a given format to a date object;
function Scand(cFormat, cValue) {
var oDate = util.scand(cFormat, cValue);
if(oDate == null) {
app.alert("Error converting date string " + cValue + " with a format of " + cFormat, 0, 1);
}
return oDate;
} // end Scand function;

// Add current date to form field;
function Now(cFormat, cName) {
var bSuccess = false;
var oField = GetField(cName);

// get the number of days to add'
var oAdjustDays = GetField("ReleaseDate");
// default value for field;
event.value = oAdjustDays.value;
// could add some code for a value of " ";
// add days if AdjustDays value is a number;
if(oAdjustDays.value != " " && isNaN(oAdjustDays.value) == false) {
// convert Today to date object;
var oBaseDate = Scand("mm/dd/yyyy", oToday.value);
// adjsut for selected nuber of days;
oBaseDate.setDate(oBaseDate.getDate() + oAdjustDays.value);
// populate date value;
event.value = util.printd("mm/dd/yyyy", oBaseDate);
}
// end custom calculation script;

Ok, so the customer doesn't want their users to have to select "14 Days" or "180 Days" from the drop-down list.  They want the dates (Today's date + 14 days and Today's date + 180 days) to populate as selections in the drop-down list, along with the option of "Permanent".  My head is spinning. Example: Today's Date: 01/19/2016; Release Date: (3 options to select from) 02/02/2016 (which is today's date + 14 days), 07/17/2016 (which is today's date + 180 days), Permanent.
