Flex4学习笔记（二）－－语法相关

1.数组的使用

	<fx:Script>
		<![CDATA[
			import mx.events.FlexEvent;

			protected function application1_initializeHandler(event:FlexEvent):void
			{
				var array2:Array = new Array("1","22","333","4444");
				var array3:Array = ["pp","qq"];
				
				text1.text = array1[2];
				text2.text = array2[3];
				text3.text = array3[1];
			}

		]]>
	</fx:Script>
	<fx:Declarations>
		<fx:Array id="array1">
			<fx:String>aa</fx:String>
			<fx:String>bb</fx:String>
			<fx:String>cc</fx:String>
		</fx:Array>
	</fx:Declarations>
	<s:TextInput id="text1" x="111" y="146"/>
	<s:TextInput id="text2" x="111" y="192"/>
	<s:TextInput id="text3" x="111" y="237"/>

 

2.定义方法中使用可变参数

	<fx:Script>
		<![CDATA[
			protected function func1(...arg):void
			{
				for each(var str:String in arg)
				{
					text1.text += str + " ,";
				}
			}

			protected function button1_clickHandler(event:MouseEvent):void
			{
				func1("aa","bb","cc","dd");
			}

		]]>
	</fx:Script>

	<s:Button x="539" y="132" label="按钮" click="button1_clickHandler(event)"/>
	<s:TextInput id="text1" x="35" y="132" width="489"/>
