海兰我试图prevent用户在AS3 textarea的成分进入任何形式的换行符。

Hy I'm trying to prevent the user to enter any form of line breaks in a as3 textarea component.

我试图用这样的textarea的限制参数：

I tried using the restrict param of the textarea like this:

foo.restrict = "^/\r\n//\n/"

但我没有任何成功。

but i don't have any success.

希望有人能帮助我走出了正确的方式来做到这一点。

Hope anybody can help me out on the correct way to do this.

在此先感谢 米兰

我不认为你可以做到这一点。解决方法是在更改事件空字符串替换墨盒的回报。

I don't think you can do that. The workaround is replacing cartridge return with empty string in the CHANGE event.

import flash.events.*;

foo.addEventListener(Event.CHANGE, test_change);

function test_change(e:Event)
{
    foo.text = foo.text.replace("\r", "");
}
