Need help spawning template

[MidEvil2023]

Have Acrobat Pro.  Brand new to Javascript and Page Templates though.  Helping someone who wants a button that can create an additional "page2" from the form.  Below is the code I am using that I found elsewhere. 

this.spawnPageFromTemplate ({
cTemplate: this.getNthTemplate(0),
bRename: false,
});
this.pageNum = this.numPages-1;
this.zoom=100;

Problems:  It creates a clone of Page2, including any text that has already been entered. Don't really want that. And if I start typing on either page, it just duplicates it across both pages (typin HELLO on page 2 also makes it appear on page 3).  Can't have that.

Use true for the rename parameter.

Thank you!    Looks like I have to do something about the page numbering in the corner as well. I will do some poking around here to see what I can find on that.

Also, is there a way to enforce a maximum amount of pages in a file?  To prevent someone from clicking this 30 times. Not a big deal, but I was asked.

" is there a way to enforce a maximum amount of pages in a file? "

You should add a condition:

if (this.numPage == 1) {
this.spawnPageFromTemplate ({cTemplate: this.getNthTemplate(0), bRename: false});
this.pageNum = this.numPages-1;
this.zoom=100;
}

You should not use the spawnPageFromTemplate method. It was replaced by the spawn method of the Template object.

[MidEvil2023]

Can you elaborate or link me to an example?

[try67]

For example:

this.templates[0].spawn({nPage: 0, bRename: false, bOverlay: false});

See the documentation for more details.

Update.  Is it possible to have page numbering that automagically changes when new pages are added?   (via the previous javas script or another method)  

[try67]

Yes, if you add it using fields, which can be updated dynamically.

" Is it possible to have page numbering that automagically changes when new pages are added?"

Yes.

Use this calculation script in a text field for static pages (where the page number is a number):

event.value = (event.target.page + 1);

Use this calculation script in a text field for templates, and spawned, pages (where the spawned page number is the last number in an array):

var aNumPag = event.target.page;
event.value = ((aNumPag[aNumPag.length-1]) + 1);
