Can I get a button to disappear when I click it?

[Former Community Member]

Really kind of a newb when it comes to some of this stuff. Any help would be appreciated.

[Thom_Parker]

Yes you can. The visibility of form elements is controlled by the "presence" attribute.



xfa.form.form1.Pg1.myButton1.presence = "visible";

xfa.form.form1.Pg1.myButton1.presence = "invisible";

Cool, but what do you do with that or where do you put it?

[Thom_Parker]

Ahhh, you are not familiar with JavaScript. To do this you are going to have to learn just a bit.



In Designer

1. select the button you want to disappear.

2. On the Script Editor window select "Click" (If the editor is not visible Look under the "Window" menu)

3. Add this line of code to the "Click" event.



this.presence = "invisible";



"this" refers to the current form element. Which because the code is inside the button click event, refers to the button.

Thank you Thank you Thank you. I never even knew that editor was there! That answers about a billion and a half of the questions/problems I have been having with this and other things. Thank you very much! Next time you're in Omaha I'm getting you a pizza.

How is this performed in old Acrobat7?

[Thom_Parker]

What do mean by "old Acrobat 7"? Do you mean an AcroForm PDF. i.e., a PDF using the standard old form fields that you add in Acrobat?



For this you use the old "display" Field Property.



this.getField("myField").display = display.hidden;



or



this.getField("myField").display = display.visible;

Yes, that's exactly what I meant Thom. Thanks for clearing that up. AND thanks for the tip! :) You've already done more than enough, but could you tell me where this would go?

[Thom_Parker]

There are lots of JavaScript locations in a PDF. Where you put it depends on how you want to use it. For example, if you wanted to make a field hidden/visible by clicking on a button you'd put this script in the Buttons "MouseUp" Action.
