Flex之旅：第一部分：flex必备基础知识积累(4)---ArrayCollection, Array赋值写法

ArrayCollection:

标签赋值写法：

比如有一个自定的类：Persion.as:

package vo
{
	[Bindable]
	public class Persion
	{
		public var id:String;
		public var age:int;
		public var name:String;
		
		public function Persion()
		{
			toString();
		}
		
		public function toString():String{
			return "{id:"+id+" age:"+age+" name:"+name+"}";
		}
	}
}

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
			   xmlns:s="library://ns.adobe.com/flex/spark"
			   xmlns:mx="library://ns.adobe.com/flex/mx"
			   minWidth="955" minHeight="600"
			   creationComplete="application1_creationCompleteHandler(event)" xmlns:vo="vo.*">
	<fx:Script>
		<![CDATA[
			import mx.events.FlexEvent;
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				trace(ac1); //Flex,Flash,Flash Media Server,Flash Lite,AIR
				trace(ac2); //{id:null age:1 name:1},{id:null age:2 name:2},{id:null age:3 name:3}
			}
			
		]]>
	</fx:Script>
	
	
	<fx:Declarations>
		<s:ArrayCollection id="ac1">
			<fx:String>Flex</fx:String>
			<fx:String>Flash</fx:String>
			<fx:String>Flash Media Server</fx:String>
			<fx:String>Flash Lite</fx:String>
			<fx:String>AIR</fx:String>
		</s:ArrayCollection>
		
		<s:ArrayCollection id="ac2">
			<vo:Persion age="1" name="1"></vo:Persion>
			<vo:Persion age="2" name="2"></vo:Persion>
			<vo:Persion age="3" name="3"></vo:Persion>
		</s:ArrayCollection>
		
		
		
		
	</fx:Declarations>
	
</s:Application>

直接赋值写法：

	// 自定义Object
	private var items:ArrayCollection=new ArrayCollection([
		{label:'Live',value1:'N',refCodeA:'LIVE'},{label:'Trading Hierarchy',refCodeA:'Trad'},{label:'Production Demo',value1:'Y',refCodeA:'PROD'},{label:'PAT Demo',refCodeA:'PAT'},{label:'Derivative Clearance Demo',refCodeA:'DCT'},{label:'Client On-Boarding Tool',refCodeA:'CONB'}
	]);
			
	// String类型		
	public var yesOrNoList:ArrayCollection = new ArrayCollection(['Y','N']);

Array:

标签赋值写法：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
			   xmlns:s="library://ns.adobe.com/flex/spark"

			   minWidth="955" minHeight="600"
			   creationComplete="application1_creationCompleteHandler(event)">
	<fx:Script>
		<![CDATA[
			import mx.events.FlexEvent;
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				trace(array1);<span style="white-space:pre">	</span>// Flex,AIR
				trace(array2);<span style="white-space:pre">	</span>// Flex0,Flash0,Flex1,Flash1,Flex2,Flash2,Java2
			}
			
		]]>
	</fx:Script>
	
	
	<fx:Declarations>
		<fx:Array id="array1">
			<fx:String>Flex</fx:String>
			<fx:String>Flash</fx:String>
			<fx:String>Flash Media Server</fx:String>
			<fx:String>Flash Lite</fx:String>
			<fx:String>AIR</fx:String>
		</fx:Array>
		
		<fx:Array id="array2" >
			<fx:Array>
				<fx:String>Flex0</fx:String>
				<fx:String>Flash0</fx:String>
			</fx:Array>
			<fx:Array>
				<fx:String>Flex1</fx:String>
				<fx:String>Flash1</fx:String>
			</fx:Array>
			<fx:Array>
				<fx:String>Flex2</fx:String>
				<fx:String>Flash2</fx:String>
				<fx:String>Java2</fx:String>
			</fx:Array>
		</fx:Array>
		
	</fx:Declarations>
	
</s:Application>

直接赋值写法：

var myArray:Array = ["one","two","three"]; 
var arr:Array = new Array("red","blue","white","black","green","yellow");


private var items:Array = [
	{label:'Live',refCodeA:'CONB'}
];

Object(如果自己懒得去写自定义Object):

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
			   xmlns:s="library://ns.adobe.com/flex/spark"
			   xmlns:mx="library://ns.adobe.com/flex/mx"
			   minWidth="955" minHeight="600"
			   creationComplete="application1_creationCompleteHandler(event)" xmlns:vo="vo.*">
	<fx:Script>
		<![CDATA[
			import mx.events.FlexEvent;
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				// 先定义，后赋值的写法（注意，这里支持嵌套）
				var o2:Object = new Object();
				o2["column1"] = "c1";
				o2["column2"] = "c2";
				o2["column3"] = "c3"; 
				o2.position = {department:"Accounting",salary:50000,title:"Junior Accountant"};
				
				// 直接赋值写法（注意，这里支持嵌套）
				var person:Object = {
					name:"John Smith",age:22,position:{department:"Accounting",title:"Junior Accountant"},id:303
				};
				
				trace(o1);
				trace(o2);
				trace(person);
			}
			
		]]>
	</fx:Script>
	
	
	<fx:Declarations>
		<!-- 标签定义写法 /-->
		<fx:Object id="o1" field1="1" field2="2" field3 = "3" />
	</fx:Declarations>
