Document Level Scripts for Template Calculations - Best Practices?

[eshrimps]

I have a page with calculations that may need to be spawned multiple times. I'm trying to sort out the most efficient approach to modifying the fields in the template.

Example: There are about 40+ fields that use the following calculation which I wrote as a document level function:

BasalArea

function BasalArea()

{

// Find field name suffix for current line

var fld = this.getField(event.target.name)

var sf = event.target.name.split(".").pop();

// Establish variables

var r = Math.PI

var diam = "F2a.DBH." + sf;

// Perform calculation

event.value = (r * Math.pow(this.getField(diam).value,2))/40000

}

I also created the following document level script to aquire the field name prefix on spawned pages:

PreFix

function PreFix()

{

// Extract prefix for fields on spawned page 

var cPreFix

var aFieldName = event.target.name.split(".");

if(aFieldName.length > 2)

// First 2 elements of name array make up the prefix;

    (cPreFix = aFieldName[0] + "." + aFieldName[1] + ".");

else cPreFix = "";

return cPreFix

}

The template itself is a copy of the original page which is hidden and I have renamed the fields slightly on the template so that they are not linked (maybe that was unnecessary since they will be again renamed when the template spawns, but I was having trouble working on the document with identical field names).

So I will create a modified calculation script for the template (using the modified field names) called

function tptBasalArea() 

So here are my questions:

1) Can a document level function reference another document level function? Can tptBasalArea() reference PreFix() or should the script for PreFix() be built into tptBasalArea()?

2) Is there a better place for a script that is only used by that template, like a page level script?

3) Have I created unnecessary inefficiencies that will slow everything down?

1) Yes, it can.

2) At the page level you can only assign code to the page's Open and Close events, but I wouldn't use those for this purpose. The rest of the scripts are either at the App, Document or Field/Bookmark/Link levels. For your purposes I think keeping it at the doc-level is the best option.

3) It seems fine to me.
