Drop downs in LiveCycle Designer

Question

I have two drop downs.  The first drop down has 5 items, the second has 20.  When the user selects a item in the first drop down I only want the second drop down to show 4 of the items.  How do I write a script for that?  Thank you!

Answer 1

I would like to know if it is an item in the first dropdown list corresponding to 4 items of the second.
If yes,you can use array.
1. In the first "exit" event
var alistName = new Array("A","B","C","D");
var alistValue = new Array("1","2","3","4");
var blistName = new Array("AA","BB","CC","DD");
var blistValue = new Array("11","22","33","44");
if(this.rawValue == "A")
for(var i=0;i<alistName.length;i++)
var name = alistName[i];
var value = alistValue[i];
DropDownList2.addItem(name,value);
if(this.rawValue == "B")
for(var j=0;j<blistName.length;j++)
var bname = blistName[j];
var bvalue = blistValue[j];
DropDownList2.addItem(bname,bvalue);
2. In the first "change" event
if(xfa.event.newText !=this.rawValue){ DropDownList2.rawValue = null; }
