Adobe LiveCycle处理重复子窗体

Question

I have repeating subforms with buttons on them. I want to be able to remove buttons that have been added with each addition of a subform. By the searching I've done, the following code should work, but it doesn't. Can someone please set me straight?

var IGdelbut = xfa.resolveNodes("ItemGroup[*].ItemHeader.Delbutton");
for (var i = 0; i < IGdelbut; i++) {
    IGdelbut.presence = "invisible";
}

(I apologize for repeating my earlier question, but I'm hoping I'm giving someone better information to work with.)

Answer 1

Your script has a couple of issues iterating over the result of resolveNodes() call. If i get this right, you are trying to hide all the * DelButton *s on the subforms.

Try the following

var allDeleteButtons = xfa.resolveNodes("ItemGroup[*].ItemHeader.Delbutton");
var len = allDeleteButtons.length;
for (var i = 0; i < len; i++) {
    allDeleteButtons.item(i).presence = "invisible";
}

Assuming you have this script on the parent subform of repeating ItemGroup subforms.
