How to add pages based on a dropdown value ?

[Anthony31413260hlxw]

I have two template pages that I would like to appear if one of the three options are selected in a dropdown menu on a first permanent page. If option A is selected, I would like the first template page to appear. If B or C is selected, I would like the second template page to appear. What is the javascript code for this ?

Assuming the dropdown values are A, B, and C, select "Commit selected value immediately" in the options tab of the dropdown then enter the following custom validation script:

if(event.value=="A")

{this.getTemplate("Template 1").spawn();}

if (event.value == "B" || event.value=="C")

{this.getTemplate("Template 2").spawn();}

But, let's say I don't want to make it show at the end of the document, but after the third page ?

I got the answer spawn(3, false, false);

this.pageNum=1}

The first "false" is whether you want the fields renamed or not.  If you only want the pages spawned once per selection of the dropdown, I would suggested using check boxes instead that spawn the page if it's checked and remove it if it's unchecked.  This article outlines in detail how to do it, with practice files you can download, and video:

if(event.value=="A")

{this.getTemplate("Template 1").spawn(3, true, false);}

if (event.value == "B" || event.value=="C")

{this.getTemplate("Template 2").spawn(3, true, false);}

Just keep in mind that with this code if the user changes their mind after selecting A and switched to B, the first page that was spawned will still be there, alongside the second page... To prevent that from happening you should check the number of pages in the file when a selection is made, and delete any spawned pages, if they exist.

Do you know why template 1 always appeared after the template that appeared accordingly to the choice in the drop down menu ?

Forget about it, I got the answer. I needed to put the different templates in the same {}

Something like this:

var t1 = this.getTemplate("Template1");
var t2 = this.getTemplate("Template2");
if (event.value == "A")
t1.spawn(this.numPages, false, false);
else if(event.value == "B" || event.value == "C")
t2.spawn(this.numPages, false, false);

You could also add to the script to delete a page, if for example you select A and then change your mind and select B or C.
