1、问题背景

     遇到这样一个问题：有四个Tab选项卡。依据不同的參数隐藏和显示选项卡

2、实现实例

（1）隐藏“春季”

protected function springClickHandler(event:MouseEvent):void{	tabs.getTabAt(0).visible = false;	tabs.getTabAt(0).includeInLayout = false;	tabs.getTabAt(1).visible = true;	tabs.getTabAt(1).includeInLayout = true;	tabs.getTabAt(2).visible = true;	tabs.getTabAt(2).includeInLayout = true;	tabs.getTabAt(3).visible = true;	tabs.getTabAt(3).includeInLayout = true;	tabs.selectedIndex = 1;}

（2）隐藏“夏季”

protected function summerClickHandler(event:MouseEvent):void{	tabs.getTabAt(0).visible = true;	tabs.getTabAt(0).includeInLayout = true;	tabs.getTabAt(1).visible = false;	tabs.getTabAt(1).includeInLayout = false;	tabs.getTabAt(2).visible = true;	tabs.getTabAt(2).includeInLayout = true;	tabs.getTabAt(3).visible = true;	tabs.getTabAt(3).includeInLayout = true;	tabs.selectedIndex = 0;}

（3）隐藏“秋季”

protected function autumnClickHandler(event:MouseEvent):void{	tabs.getTabAt(0).visible = true;	tabs.getTabAt(0).includeInLayout = true;	tabs.getTabAt(1).visible = true;	tabs.getTabAt(1).includeInLayout = true;	tabs.getTabAt(2).visible = false;	tabs.getTabAt(2).includeInLayout = false;	tabs.getTabAt(3).visible = true;	tabs.getTabAt(3).includeInLayout = true;	tabs.selectedIndex = 0;}

（4）隐藏“冬季”

protected function winterClickHandler(event:MouseEvent):void{	tabs.getTabAt(0).visible = true;	tabs.getTabAt(0).includeInLayout = true;	tabs.getTabAt(1).visible = true;	tabs.getTabAt(1).includeInLayout = true;	tabs.getTabAt(2).visible = true;	tabs.getTabAt(2).includeInLayout = true;	tabs.getTabAt(3).visible = false;	tabs.getTabAt(3).includeInLayout = false;	tabs.selectedIndex = 0;}

（5）显示“四季”

protected function fourClickHandler(event:MouseEvent):void{	tabs.getTabAt(0).visible = true;	tabs.getTabAt(0).includeInLayout = true;	tabs.getTabAt(1).visible = true;	tabs.getTabAt(1).includeInLayout = true;	tabs.getTabAt(2).visible = true;	tabs.getTabAt(2).includeInLayout = true;	tabs.getTabAt(3).visible = true;	tabs.getTabAt(3).includeInLayout = true;	tabs.selectedIndex = 0;}

3、实例结果

（1）初始化

（2）点击“春季”button

（3）点击“夏季”button

（4）点击“秋季”button

（5）点击“冬季”button

（6）点击“四季”button
