如何基于as3flash中的其他combobox动态更改combobox值

您应该为combobox1分配一个事件处理程序,如:

    var myXML:XML= <tree>
                       <branch name='1'><node name='1'/><node name='2'/><node name='3'/></branch>
                       <branch name='2' ><node name='1'/><node name='2'/><node name='3'/></branch>
                       <branch name='3'><node name='1'/><node name='2'/><node name='3'/></branch>
                   </tree> // or something like this



    combobox1.addEventListener(Event.CHANGE,changeListener); 


    function changeListener(e:Event):void
    {
         populateCombobox2(myXML.branch.(@name == e.currentTarget.selectedItem.@name));
    }

    function populateCombobox2(combo2Data:XML):void
    {
        combobox2.dataSource = combo2Data;
        combobox2.displayName = "@name"; // I don't remember if this is correct, and I can't 
                                         //check it now, but this is the logic.... if its not 
                                         //correct tell me, and when I get home I can tell you 
                                         //the correct way
    }
