comboBoxInstance.selectedItem
Property; the value of the selected item in the drop-down list.
If the combo box is editable, selectedItem returns undefined if the user enters any text in the text box. The property only has a value if you select an item from the drop-down list or set the value using ActionScript. If the combo box is static, the value of selectedItem is always valid; it returns undefined if there are no items in the list.
With a ComboBox component instance my_cb, the following example shows the values for the selectedItem data and label properties:
// Add Items to List.
my_cb.addItem({data:1, label:"First Item"});
my_cb.addItem({data:2, label:"Second Item"});
my_cb.addItem({data:3, label:"Third Item"});
my_cb.addItem({data:4, label:"Fourth Item"});
var cbListener:Object = new Object();
cbListener.change = function(evt_obj:Object) {
var item_obj:Object = my_cb.selectedItem;
var i:String;
for (i in item_obj) {
trace(i + ":\t" + item_obj[i]);
}
trace("");
};
my_cb.addEventListener("change", cbListener);
ComboBox.dataProvider, ComboBox.selectedIndex
