Adobe Acrobat

Greetings:

BACKGROUND INFO: I am creating a Travel Application / Reimbursement form in which I need to make the reimbursement column of fields "hidden" (application phase) or "visible" (reimbursement phase). I am using many scripts like the one below to reference each field (labelled a,b,c,...aa,bb,cc...) placed under the click event of a button (I tried using a drop-down box to select "Travel Application" or "Reimbursement Request" but the results were not consistent).

if(xfa.resolveNode("#subform.EstimateofExpenses.Table2.Row1[1].b").presence=="hidden")then
xfa.resolveNode("#subform.EstimateofExpenses.Table2.Row1[1].b").presence="visible"
elseif(xfa.resolveNode("#subform.EstimateofExpenses.Table2.Row1[1].b").presence=="visible")then
xfa.resolveNode("#subform.EstimateofExpenses.Table2.Row1[1].b").presence="hidden"
endif

PROBLEM: One of my fields is set with the ability to have multiple instances. The show/hide scripts work on all fields except for the instances. I do not know how to reference the other instances in script...

If anyone could give some pointers on this, it would be much appreciated. Thanks!

You will need a for loop to address all instances of an object.
Here an example in FormCalc.

1: Count the current instances of your repeatable object.

var nRow = Table2.Row1.instanceManager.count

2: Initiate the loop

for (i = 0 upto nRow -1  do)
Table2.Row1[i].b.presence = "hidden"
endfor

If you use FormCalc it's generally not necceassary to use the resolveNode method because FormCalc can address objects much easier than JavaScript!
The benefit is a much slimmer script syntax.
