flex中为控件添加监听器并计算

1、添加监听器：

public function moduleCreationComplete():void

            {

                this.D601_29a.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_28);

                this.D601_30a.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_28);

                this.D601_31a.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_28);

                this.D601_29b.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_28);

                this.D601_30b.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_28);

                this.D601_31b.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_28);

                this.D601_36.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_35);

                this.D601_37.addEventListener(FlexEvent.SELECTION_CHANGE,setD601_35);

                this.D601_65.addEventListener(FlexEvent.CHANGING,setD601_07);

                this.D601_65.addEventListener(FlexEvent.ENTER,setD601_07);

            }

2、写计算函数：

public function setD601_28(event:Event):void

            {//计算小时分钟

                var firsta:Number = Number(this.D601_29a.text);

                var firstb:Number = Number(this.D601_29b.text);

                var seconda:Number = Number(this.D601_30a.text);

                var secondb:Number = Number(this.D601_30b.text);

                var thirda:Number = Number(this.D601_31a.text);

                var thirdb:Number = Number(this.D601_31b.text);

                this.D601_28a.text = (Math.floor(((firsta + seconda + thirda)*60 +firstb + secondb + thirdb) / 60)).toString();

                this.D601_28b.text = (((firsta + seconda + thirda)*60 +firstb + secondb + thirdb) % 60).toString();

            }

            public function setD601_35(event:Event):void

            {

                var chanshi:Number = Number(this.D601_36.text);

                var chanhou:Number = Number(this.D601_37.text);

                this.D601_35.text = (chanshi + chanhou).toString();

            }

            public function setD601_07(event:Event):void

            {//根据身份证号计算年龄
                var cardId:String = this.D601_65.text;

                if(cardId.length >= 16)

                {

                    var year:Number = Number(this.D601_65.text.substr(6,4));

                    var month:Number = Number(this.D601_65.text.substr(10,2));

                    var day:Number = Number(this.D601_65.text.substr(12,2));

                    var date:Date = new Date();

                    var nowMonth = date.month + 1;

                    var age = date.fullYear - year;

                    if(month > nowMonth || month == nowMonth && day >= date.date)

                    {

                        age++;

                    }

                    this.D601_07.text=age;

                }

            }
