日期字段范围 - Flex
我有两个日期字段。有没有一种方法可以将第二个日期字段的日期设置为指定范围（比如说三天......？我尝试这样做但没有成功......不知道将日期转换回字符串并且格式化它..这是代码
<mx:DateField disabledRanges="{[{rangeEnd: new Date(2011,05,31)}]}" id="dfield1" change="leaveDate()" parseFunction="null" width="100" x="156" y="130"/>
<mx:DateField disabledRanges="{[{rangeEnd: new Date(2011,05,31)}]}" id="dfield2" parseFunction="null" width="100" x="426" y="130"/>
private function leaveDate():void {
//var dateLeave:Date = dfield1.selectedDate;
var myTime:Date =dfield1.selectedDate;
dateAdd("date", 3, myTime);
//car formatter1:Datef
commentField.text+=myTime+"\n"
//dfield2.selectedDate = returnDate
}
public static function dateAdd(datepart:String = "", number:Number = 0, date:Date = null):Date
{
if (date == null) {
date = new Date();
}
var returnDate:Date = new Date(date.time);;
switch (datepart.toLowerCase()) {
case "fullyear":
case "month":
case "date":
case "hours":
case "minutes":
case "seconds":
case "milliseconds":
returnDate[datepart] += number;
break;
default:
/* Unknown date part, do nothing. */
break;
}
return returnDate;
}
如果有人可以提供帮助，我将非常感激
