var beg_:String = REG_DATE_BEGIN.text;

var end_:String = REG_DATE_END.text;

var beg:Date=new Date(beg_.substr(0,4), (parseInt(beg_.substr(4,2))-1), beg_.substr(6,2));

var end:Date=new Date(end_.substr(0,4), (parseInt(end_.substr(4,2))-1), end_.substr(6,2));

if(end.getTime()<beg.getTime()){

Alert.show( "[结束时间]必须大于[开始时间],请重新选择" );

return;

}

if((end.getTime()-beg.getTime())> (1000*60*60*24*30)){

Alert.show( "查询时间间隔不能超过1个月" );

return;

}

实际运用

var o:Object=getValues(); //拿到值

var beg:String=o.CNT_DATE_B;

var end:String=o.CNT_DATE_E;

var beg_dt:Date = DateField.stringToDate(beg, "YYYYMMDD");

var end_dt:Date = DateField.stringToDate(end, "YYYYMMDD");

var disTime:Number = Number(end_dt.getTime() - beg_dt.getTime());

var yoy_begin:String=o.YOY_DATE_E;

var beg_yoy_begin:Date = DateField.stringToDate(yoy_begin, "YYYYMMDD");

YOY_DATE_B.selectedDate = new Date(beg_yoy_begin.getFullYear(), beg_yoy_begin.getMonth(), Number((beg_yoy_begin.getDate() - disTime/(1000*60*60*24))));
