Question

I am using a combobox for the us states, link. The label is set to the full name of the state, while the value attribute holds the abbreviation. What I want to do is to get the selected item’s value. So I tried combo.selectedItem.value and combo.selectedItem.@value, but neither of them worked. Can someone shed a light on this please?

Answer 1

Here’s a simple example that might be helpful.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
 <mx:ComboBox id="comboBox" dataProvider="{[{label:'California', value:'CA'}, {label:'New York', value:'NY'}]}" />
 <mx:Label text="{comboBox.selectedItem.value}" />
</mx:Application>

Here’s another example. In this one we use XML as dataProvider.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:XML id="xml" xmlns="">
        <states>
            <state label="Alabama" value="AL" country="US" />
            <state label="Alaska" value="AK" country="US" />
            <state label="Arkansas" value="AR" country="US" />
        </states>
    </mx:XML>
    <mx:ComboBox id="comboBox" dataProvider="{xml.state}" labelField="@label" />
    <mx:Label text="{comboBox.selectedItem.@value}" />
</mx:Application>
