说明:FlexAboutButton.mxml中汇总了button的click事件的写法
第一种click事件触发，调用一个方法[写在Script中的方法]
click="submitButtonClickHandler(event)"
第二种click事件触发，调用的方法写在按钮的内部
<mx:Button id="btnshow" label="淅沥的小雨不停的下">
<mx:click>
<![CDATA[
import mx.controls.Alert;
Alert.show("下雨吧~~~",4);
]]>
</mx:click>
</mx:Button>
第三种click事件触发
click="lblword.text='你好么'"
第四种click事件，是在页面加载完成以后触发的事件中注册的方法
