Populate a dropdown list with function

[Former Community Member]

I've just recently started using LiveCycle Designer (7.0) and learning JavaScript. I am learning a lot perusing this forum but picking things up piecemeal. I can't figure this out.



I have multiple subform instances with the same objects. One of those objects is a drop-down list. When the form is loaded, I want to assign the same list items to each drop-down on each subform using a function. For instance, this function is the script object Enrollment.SelectedPayers.#variables[0].#script[0]:



function fillList(myList)

{ myList.clearItems()

myList.addItems("Name1","ID1")

myList.addItems("Name2","ID2")

myList.addItems("Name3","ID3")

}



I want to fill Enrollment.SelectedPayers.Payer[*].PayName by calling this function.



Questions:

Where should I call the function so the lists will be filled when the document loads?

How do I call the function so it updates the drop-down? Using direct reference or variable?



This, of course, is a very simplified version of what I'm actually doing. I would appreciate any examples you can provide. I do know how to iterate through the Payer subforms.

Hi,



I assume,
PayName is a subform within all the
Payer subforms. (?)

Then... the following code-fragment should work, if put in the initialize-event of your form.






var arrPayers = xfa.resolveNodes("Enrollment.SelectedPayers.Payer[*]");

for(i in arrPayers)

    myScriptingObj.fillList(i.PayName);





Notice, that you must replace
myScriptingObj with the name of the scripting object, where
fillList(obj) is located in.

Thanks, but this doesn't work either. The dropdowns aren't populated. What am I missing? Here's what I have:



Enrollment::initialize

var arrPayers = xfa.resolveNodes("Enrollment.SelectedPayers.Payer[*]");

for(i in arrPayers)

Enrollment.#variables[0].MyFunctions.fillList(i.PayName);



Enrollment.#variables[0].MyFunctions

function fillList(oPayer)

{ oPayer.clearItems()

oPayer.addItem("ACORDIA","45")

oPayer.addItem("BLUE CROSS","1") }



PayName is the dropdown list within each Payer subform.

Well, I've made some progress. I'm learning how to use the JavaScript debugger. My first problem was in the way I called the function. I'm still learning the naming conventions and hierarchy. So now the code is:



for(i in arrPayers)

MyFunctions.fillList(i.PayName);



Now the error is in the function - TypeError: oPayer has no properties. So why isn't it recognizing oPayer as the dropdown list object it should be?
