Code on button needs to work throughout all instances

Question

Hello,
I have a subform with an 'ADD' button and a 'HIDE' button.
The 'ADD' button adds an instance of the subform.
The 'HIDE' button unhides a white box which makes the ADD button go invisible. Both buttons travel with the new instance.
When I ADD an instance of the subform and then go to the new page and try to HIDE the new ADD button it does not work.
I assume it is because I am unhiding the whitebox by name and once it is repeated the name changes.
Question: How can I have code within an instanced subform that works regardless of it's name?

Answer 1

I would just use the "parent/child" addressing system.
In the click event of your hide button add:
this.parent.AddressOfTheAddButtonFromTheInstance.presence = "invisible";
May need to add more "parents" (e.g. this.parent.parent.parent) depending on if you have the hide button wrapped in a few subforms.
Hope thsi helps,
Tom
P.S.
What S. Bishiop is saying to use is the addressing of each instance as an individual item, e.g. :
for (var i=0; i < Question2.DeviceForm._Device.count; i++)
Question2.DeviceForm.Device.all.item(i).PositionedWrap.DeviceType.mandatory = mandatorySetting;
This loops through every instance of the repeating form "Device" and sets a field to being mandatorySetting (error or disabled, depending on what I want, in this case).
