Flex4 DateChooser控件之SCroll事件来设定年月

首先要设定当前年和月：

//日历设置变量,当前日历控件中的年和月
public var currentMonth:Number;
public var currentYear:Number;

.........................................
.........................................

	this.currentYear=new Date().getFullYear();
	this.currentMonth=new Date().getMonth()+1;
	//因为月份从0开始计数，所以要加上1。
	
	trace("****:\t"+currentMonth+"/"+currentYear+"******");
	
           

然后在DateChooser控件中申明

<mx:DateChooser         id="dateChooser" x="139" y="83" borderColor="green"
			scroll="changeMonth(event)" />
           

然后在changeMonth(event)事件中实现其事件，细节如下所示：

private function changeMonth(event:DateChooserEvent):void{
	
	trace(event.detail);
//  mx.controls.Alert.show("hello world!!!");
  
  //获取选中的月份
//  mx.controls.Alert.show("当前的月份:\t"+dateChooser.selectedDate.getMonth().toString());
	
	//有四种情况
	//nextMonth   &&  previousMonth
	//nextYear      &&  previousYear
	
	
var currentValue:String = new String(event.detail);
   if(currentValue == "nextMonth"){
	    if(currentMonth >= 1 && currentMonth < 12) 
		this.currentMonth += 1;
		else{
			this.currentMonth = 1;
			currentYear+=1;
		}
	}
	else if(currentValue=="previousMonth"){
		if(currentMonth > 1) 
			this.currentMonth -= 1;
		else{
			this.currentMonth = 12;
			currentYear -= 1;
		}
		}
		
	else if(currentValue == "nextYear"){
		if(currentYear == 2100)
		return;
		currentYear += 1;
			
	}
	else if(currentValue=="previousYear"){
		if(currentYear == 1900)
			return;
			currentYear -= 1;
		
	}
   
   //根据选中的年月来进行重新加载数据至DataGrid控件中
   getAllCalenderService=new HTTPService();
   getAllCalenderService.url="http://192.168.17.66:8080/Smarter/calendarSetting!getMonthSettings.action?year="+currentYear+"&month="+currentMonth;
   getAllCalenderService.method="post";
   getAllCalenderService.addEventListener(ResultEvent.RESULT,getAllCalenderFunc);
   
   getAllCalenderService.send();
   //重新向服务器后台取数据
}
