Deleting multiple spawned pages - Adobe Pro DC

Question

Hi everyone.

I have created an application form (pages 1-3) which the applicant fills out. I have a hidden button which spawns a permit (pages 4-7) - all four pages appear together. Re-clicking the button deletes pages 4-7, but it deletes one page at a time i.e. requires four clicks. Is there a way to delete pages 4-7 with one click? Using Adobe Acrobat DC, Windows 10.

Here is the script I'm using:

// This script is activated by "Mouse-Up" on a hidden button

// Get a reference to the template

var t1 = getTemplate("Pg4");
var t2 = getTemplate ("Pg5");
var t3 = getTemplate ("Pg6");
var t4 = getTemplate ("Pg7");
var spwndel = this.numPages;
// Create a new page, but only if there's currently only three pages in this document;

if (numPages == 3)
{

t1.spawn({nPage: numPages, bRename: true, bOverlay: false});
t2.spawn({nPage: numPages, bRename: true, bOverlay: false});
t3.spawn({nPage: numPages, bRename: true, bOverlay: false});
t4.spawn({nPage: numPages, bRename: true, bOverlay: false});
// this piece works - it adds the correct pages
} else
{

// this piece deletes pagespages 4, 5, 6 and 7 , but have to click 4 times

if(numPages>3)
{
deletePages(3);
deletePages(4);
deletePages(5);
deletePages(6);

}

Any help gratefully received!

The action you are seeing is a bit odd. If you follow the logic, this code is expected to fail, just not in the way you have described. For example, when page 3 is deleted the document is shortened by one page, so there is no page 6. However, there is a page 4, so I would expect two pages to be deleted before the failure.

Have you looked in the console window to see what errors are reported, because there are errors.

Here is a "dressed" (i.e. neater) version of your code.

if (this.numPages == 3)
{
    this.getTemplate("Pg4").spawn(this.numPages,false, false);
    this.getTemplate("Pg5").spawn(this.numPages,false, false);
    this.getTemplate("Pg6").spawn(this.numPages,false, false);
    this.getTemplate("Pg7").spawn(this.numPages,false, false);
} else if(numPages>3)
{
    this.deletePages(3,6);
}

Note that the renaming argument is false. There is no need to rename fields if the template will only ever be spawned once.

Try this:

this.deletePages(3,6);

You are also missing an explicit document object reference from the document function calls. It is a good practice to include "this". 🙂 pun intended.

Here's the reference entry for the deletePages function
