Button to show/ hide page templates

  • October 6, 2023

I have a check box button on page 1.  The following code works to show/hide page 2 .  Click the button, show page 2.  Unclick the button, hide page 2.

 

However, it gives me a "bad parameter" despite working.  Any ideas?

 

if(event.target.value!="Off")
{this.getTemplate("2" ).hidden=false;}
else
{this.getTemplate("2" ).hidden=true;}

    It has two pages.  First page is always visible.  2nd page is what the button will show/hide.  Button is on page 1.

    How do I set target page number?

     


    Ok the target page isn't set. That is the source of the error.   Page numbers in the Acrobat JavaScript model are zero based. Page #1 is 0, and Page #2 is 1;

     

    Use this code:

    if(event.target.value!="Off")
{this.getTemplate("2" ).spawn(1, false, false);}
else
{this.deletePages(1);}

    Is the Template named "2"?  If not I don't see how the code could work. Also, unhiding a template always places the page at the end of the document. You can't specify the page where it will appear. 

     

    Also, hiding and showing a template will not work in Reader. The correct way to use a template is to "spawn" it. 

    This thread provides a checkbox spawn solution:

    I tried the code from the thread you provided and nothing happened

    if(event.target.value!="Off")
{this.getTemplate("2" ).spawn(nTargetPageNumber, false, false);}
else
{this.deletePages(nTargetPageNumber);}

    Hi Sir,

     

    When I click the checkbox, page 2 is deleted.  When I unclick it, nothing happens.  There is no way to bring back page 2.  So this code doesn't appear to work still.

    Also, this bad parameter error prevents me from saving this document.
