我对AS3很新,所以这是我的问题。
我有两个文本输入框p1和p2。我想做一个条件测试,看看p1是否有焦点。如果没有,则p2必须具有焦点。这是我试图开始工作的一些代码。
if ((Selection.getFocus()) == (p1totalScore.text)){
p1Score();
} p2Score();
感谢您的帮助。

如果没有FocusManager,您可以测试舞台返回焦点的位置:
(如果在艺术板上有textInput1和textInput2)
import flash.events.MouseEvent;
import fl.controls.TextInput;
var textInput1:TextInput;
var textInput2:TextInput;
stage.addEventListener(MouseEvent.CLICK, mouseClickHandler);
function mouseClickHandler(event:MouseEvent):void
{
if(stage.focus == textInput1.textField)
trace("text field 1 has focus.");
else if(stage.focus == textInput2.textField)
trace("Text field 2 has focus.");
}
我认为比您尝试更好的方法是为焦点更改添加事件处理程序:
import fl.controls.TextInput;
import fl.managers.FocusManager;
import flash.events.FocusEvent;
var textInput1:TextInput;
var textInput2:TextInput;
var focusManager:FocusManager = new FocusManager(this);
textInput1.addEventListener(FocusEvent.FOCUS_IN, textInput1FocusHandler);
textInput2.addEventListener(FocusEvent.FOCUS_IN, textInput2FocusHandler);
function textInput1FocusHandler(event:FocusEvent):void
{
trace("textInput1 has focus.");
}
function textInput2FocusHandler(event:FocusEvent):void
{
trace("textInput2 has focus.");
}

我刚刚更改了函数以返回具有焦点的控件的名称,而不是其示例返回的实例名称。
private function focusChange(e:FocusEvent):void {
var ti_now:InteractiveObject;
ti_now = fm.getFocus();
trace("Focus now: ", ti_now.name);
}
