populate a drop down list from another drop down list

[jess_us]

I have 2 dropboxes. Dropbox 1 is a list of names. Dropbox 2 is a list of numbers, each number corresponds to a name in dropbox 1

Dropbox1 - Names

     - Bill

     - John

     - Roberta

Dropbox2 - numbers

     - 0000 (Bill's number)

     - 1111 (Roberta's number)

     - 2222 (John's number)

Is it possible to select a name in Dropbox 1 and have the corresponding number for each name show in dropbox 2?

Thank you in advance for any help and input!

Simple.

Two combos, one has names, one has numbers

In the change event (javascript) for DropDownList1 put:

if ($.boundItem(xfa.event.newText) == "Bill") {
  this.resolveNode("DropDownList2").rawValue = "0000";
}

else if ($.boundItem(xfa.event.newText) == "John") {
  this.resolveNode("DropDownList2").rawValue = "1111";
}

else if ($.boundItem(xfa.event.newText) == "Roberta") {
  this.resolveNode("DropDownList2").rawValue = "2222";
}

NOTE: Unless you make your second combo readonly, you will be able to select a different number regardless of what is selected in the first.

Nice; I'm going to bookmark this one.

I'm guessing the Case statement would be helpful here too.

Sure thing, a switch can be used too.

You could alternatively use this javascript in DropDownList1's change event:

switch($.boundItem(xfa.event.newText))

{

case "Bill":

this.resolveNode("DropDownList2").rawValue = "0000";

break;

case "John":

this.resolveNode("DropDownList2").rawValue = "1111";

break;

case "Roberta":

this.resolveNode("DropDownList2").rawValue = "2222";

break;

default:

break;

}
