闪存AS3：ENTER不会被检测到，但Ctrl + Enter优良工程 [英] Flash AS3: ENTER does not get detected, but CTRL+ENTER works fine

问题描述

在我的重点是输入文本字段中，pressing CTRL + ENTER 的作品，但 ENTER 做不是。

When my focus is inside the input text field, pressing CTRL+ENTER works but ENTER does not.

pressing 输入时，我的重点是任何地方，但在输入文本字段工作得很好。

Pressing Enter when my focus is anywhere BUT the input text field works just fine..

我的目的是检测是否 ENTER 键pressed用户填写后场，但它似乎只对 Ctrl + Enter

My intention is to detect if ENTER key was pressed after the user fills out the field, but it seems to only work for CTRL+ENTER

的ActionScript 3

// works:
stage.addEventListener(KeyboardEvent.KEY_DOWN, enterHandler);

// ignored:
email.addEventListener(KeyboardEvent.KEY_DOWN, enterHandler);

function enterHandler(event:KeyboardEvent):void{
    if(event.keyCode == Keyboard.ENTER ){
        email.text = 'Thanks!';
    }
}

ENTER 结果的字符code 的== 0，而 Ctrl + Enter 是字符code 的== 13

ENTER results in charCode == 0, whereas CTRL+ENTER is charCode == 13

电子邮件使用文本工具创建并设置为可编辑

email was created using the Text tool and set to "Editable"

注意：我测试在Chrome和Firefox运行Flash V10

Note: I am testing in Chrome and Firefox running Flash v10

推荐答案

我假设你正在调试你的日常生活工作（控制>测试影片>在Flash Professional 的）？这里的问题是，键盘快捷键有precedence在键盘事件和回车键是键盘快捷键的控制>播放的在控制的菜单，而你是测试你的电影。

i'm assuming you're debugging your work in ADL (Control > Test Movie > in Flash Professional)? the problem here is that the keyboard shortcuts have precedence over keyboard events and the enter key is the keyboard shortcut for Control > Play in the Control menu while you are testing your movie.

然而，这是可能的，很容易禁用快捷键，同时测试你的电影。当你的影片播放，转到 控制>禁用快捷键的。现在你的键盘事件，回车键将正确执行。

however, it's possible and very easy to disable the keyboard shortcuts while testing your movie. when your movie is playing, goto Control > Disable Keyboard Shortcuts. now your keyboard event for the enter key will execute properly.

哦，你应该使用 event.key code 而不是 event.char code 。

oh, and you should use event.keyCode instead of event.charCode.

好吧，如果你想输入的键盘事件，火灾，当你正在里面输入文本字段，你只需要TextEvent，并将监听器添加到文本字段：

ok, if you want Enter keyboard event to fire when your currently inside an input TextField, you simply have to add TextEvent listener to the TextField:

import flash.events.TextEvent;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;
import flash.text.TextFieldType;

var tf:TextField = new TextField();
tf.border = true;
tf.multiline = true; //Must be set to true for the textField to accept enter key
tf.type = TextFieldType.INPUT;
tf.width = 200;
tf.height = 20;

tf.addEventListener(TextEvent.TEXT_INPUT, keyboardReturnHandler);       

function keyboardReturnHandler(evt:TextEvent):void
    {
    if  (evt.text == "\n")
        {
        evt.preventDefault();
        trace("text field enter");
        }
    }

addChild(tf);
