Flash as中ComboBox类的应用

Flash as中ComboBox类的应用

下面是Flash as中ComboBox类应用的相关实例

一名为my_cb的comboBox组件中，分别包含有beijing,shanghai,tianjin, chongqin四个label
另外有一my_btn的按纽

当在列表中选择beijing后，点击my_btn将跳转到标签名为"beijing"的那一帧
当在列表中选择shanghai后，点击my_btn将跳转到标签名为"shanghai"的那一帧
当在列表中选择tianjin或chongqin后，点击my_btn将跳转到标签名为"TC"的那一帧

代码如下：
stop();

    var my_city:Array = new Array(
   {label:"beijing",data:"beijing"},
   {label:"shanghai", data:"shanghai"},
   {label:"tianjin", data:"tianjin"},
   {label:"chongqing", data:"chongqing"});

       var my_Listener:Object = new Object();
       my_Listener.change = function(eventobj:Object):Void  {
       city = eventobj.target.selectedItem.label;
       };
       //添加监听
       my_cb.addEventListener("change", my_Listener);
       my_cb.dataProvider = my_city;
      
      
       error1 = "notTooGood";
       error2 = "notGood";
      
      
       function citycheck() {
       if (my_cb.selectedItem.label =="shanghai") {
              gotoAndPlay("shanghai")
              }
       if (my_cb.selectedItem.label =="tianjin") {
              gotoAndPlay("tianjin")
       } else {
              city = error2;
       }
       };

my_btn.onRelease = function() {
citycheck();
};
