HI
 
I have a drop-down list displaying for instance Apple, Orange, Banana. But I don't want to have the text value displayed when selected but the item value
 
Value | Text
1 Apple
2 Orange
3 Banana
  
And you pick Apple I would like to get 1 displayed or as return value.
 
Any idea with JavaScript?

Hi,

To get value of dropdown or listbox, it will depends on in which event your script is going to be written.

If you're tring to get the value in dropdown field's own event like change, you'll need to refer to xfa.event.newText for new text changed by user and use it to get the value by using boundItem method.

var myDDNewValue = this.boundItem(xfa.event.newText);
When you need to get the value of dropdown in other field's event, then you'll only need to refer to rawValue of the dropdown object.

var myDDValue = DropDownList.rawValue

Hi,

OK, this is what I used to test last week.

dropdown - change
xfa.host.messageBox ("this.boundItem(xfa.event.newText) : " + this.boundItem(xfa.event.newText) + "\n" +"xfa.event.newText : " + xfa.event.newText);
place it in change event of the dropdown, and if it doesn't work, then I guess I have to leave this topic to somebody else.


button - click
xfa.host.messageBox("DropDownList1.rawValue : " + DropDownList1.rawValue + "\n" +"DropDownList1.getDisplayItem(DropDownList1.selectedIndex) : " + DropDownList1.getDisplayItem(DropDownList1.selectedIndex));
