当年啥都不懂,写个比较Date的函数,用了最蠢的办法:
- /**
- * 时间验证函数
- * */
- protected function checkingDate( firstDate:String, secDate:String):Boolean
- {
- if(int(firstDate.substr(0,4))>int(secDate.substr(0,4)))
- {
- AlertUtil.AlertShow("日期范围有误,请确保结束日期在开始日期之后","错误提示",Alert.OK, this,null,3);
- return false;
- }
- else if(int(firstDate.substr(5,2))>int(secDate.substr(5,2)))
- {
- AlertUtil.AlertShow("日期范围有误,请确保结束日期在开始日期之后","错误提示",Alert.OK, this,null,3);
- return false;
- }
- else if(int(firstDate.substr(8,2))>int(secDate.substr(8,2)))
- {
- AlertUtil.AlertShow("日期范围有误,请确保结束日期在开始日期之后","错误提示",Alert.OK, this,null,3);
- return false;
- }
- return true;;
-
- }
后面突然发现有现成的封装好的函数调用可以用来实现,而且用户友好性更强

网上看到了一些比较Date的方法,摘过来,貌似比我的简单~~学习~没验证过
1. ObjectUtil.dateCompare(date1,date2)
2. ObjectUtil.dateCompare(date1,date2) 返回值为int类型
date1 > date2 1
date1 = date2 0
date1 < date2 -1
3. 自定义方法
/* 比较两个日期大小 */
public static function compare(date1:Date, date2:Date):int {
if (Number(date1) < Number(date2)) {
return -1
}
if (Number(date1) == Number(date2)) {
return 0;
}
return 1;
}
