Question

我试图在我的flash文件中创建一个对象，仅在屏幕上显示某个对象时才响应键盘。但是，使用我当前的代码（如下），如果按住某个键，它将允许您完成整个程序。我想让它在每次物体进入屏幕时重新按下键。（程序在as2中）。谢谢！

您可以使用简单的select distinct ug.* from table_x x join usergroups ug on x.userId = ug.userId where x.ip_address in ( select x.ip_address from table_x x join usergroups ug on x.userId = ug.userId group by ip_address having count(distinct groupId) > 1)语句来验证您的对象是否存在：
