How do I get the current date to show in the document and also print?

Question

Hello! This is lengthy but I wanted to try to include all relevant information. I already appreciate that you're here and I hope you can help.

I'm on Windows 7 using Acrobat Pro DC.

I've been Googling all day and trying different things and I can't seem to figure it out.

I want the form to show the current date when the file is opened.

And I also want the current date to print exactly how you see it in the file.

I need to know where to put the JS code (and to verify the one I'm using is correct).

My method:

Open the document

Tools

Prepare form

Place a text box with Text inside

Click All Properties

Now here is where my findings branch off...

1) One method tells me to click on Format then choose Date from the dropdown, then I choose my style, mmmm d, yyyy

I don't know what to do from there.

2) Another method tells me to click on Format then choose Calculate, choose Custom Calculation Script, Edit, then paste JavaScript code.

I've found variations of this code, but this is the one I used:

var myfield=getField("Text");

var date = new Date();

date=util.printd("mmmm d, yyyy", date);

a) And another suggestion was to goto Tools, JavaScript, Document JavaScripts, Add start, use:

this.getField("Today").value = util.printd("mm/dd/yyyy", new Date());

I don't know which method is more "correct" or if I'm even using the correct JS is the correct places.

I want to specify that I want the current date to show on the page when the document is opened. Currently, I cannot see the date on the page.

Any guidance would be greatly appreciated!!

If you want today's date to appear on a form or in a PDF when it is opened the easiest way is to use a form field and a script to populate the form when the PDF is opened. The form field needs to be set to "Read Only" unless you want the user to override the value of the field. To have the field display and print one sets the filed's display property to "Display". If you are using a script to populate the field I would let the script set the format for the displayed field so this field works similar to date fields that have user entry.

As for using the "Custom Calculation JavaScript", do not use it. This will only work if you have at least one other field with a calculation. This is needed to trigger the recalculation of the form. Also using this approach will cause the auto fill date field to recalculate each time any calculation on the form is triggered. This is a waste of time and could under some circumstances cause the field's value to change.

I prefer to use the document level script since this script only runs when the form opened and not a second time.

There are some possible situations that you do not discuss. What happens if the form is reset or saved, closed, and reopened?

Resetting the form will clear the field and not repopulate it.

For the save, close and reopen the date field will change.

So I would use a script that includes use of the default value of the form to hold the date value when the form was first opened and is tested to see if there is no value before updating the value of the field and setting the default value of the field. In this manner the date field will only populate if the field has not be populated and will restore the date the form was first opened if the form was reset. Also it is possible to edit the form and then remove the default value from the field before saving the updated form for distribution to others and have the date field properly update.

var 0Date = this.getField("Today");

if(oDate.defraultValue == "")

{

oDate.defaultValue = util.printd("mmmm d, yyyy", new Date());

oDate.value = oDate.defaultValue;

}

I would just add that line after gkaiseril's script:this.dirty = false;So, an user that just opens the document and close it will not be prompted to save.

I want the form to show the current date when the file is opened.

And I also want the current date to print exactly how you see it in the file.
