如何用语言查找字符按键？ [英] How to find out the character pressed key in languages?

问题描述

我不能在KeyboardEvent中使用charCode或keyCode来找出被压缩的字符，因为即使我更改了键盘布局，charCode和keyCode也不会改变（如果按相同的键）。

I can't use charCode, or keyCode in KeyboardEvent to find out the character pressed, because even if I change the keyboard layout, charCode and keyCode are not change (if press the same key).

所以，如何找到被压制的字符，按照当前的键盘布局？

So, how to find the presssed character, following to the current keyboard layout?

我已经找到这个问题，但是该文件说：

I already found this question, but what the document said:

charCode属性是当前
字符集中该键的数字
值（默认字符
设置为支持ASCII的UTF-8）。

The charCode property is the numeric value of that key in the current character set (the default character set is UTF-8, which supports ASCII).

不正确。

编辑：我使用的是Flex 4。

推荐答案

我找到了解决方案。

我们可以收听TextEvent 。此事件不仅会分发到文本组件，而且还会分派实现UIComponent的所有重点组件。

We can listen for TextEvent. This event not only dispatches to text components, but also all focused components that implement UIComponent.

例如：

package champjss
{
    import flash.events.TextEvent;
    import mx.core.UIComponent;

    public class EditorComponent extends UIComponent
    {
        public function EditorComponent()
        {
            super();

            addEventListener(TextEvent.TEXT_INPUT, handleTextEvent);
            setFocus();
        }

        protected function handleTextEvent(event:TextEvent):void
        {
            // This text the text that user types,
            // following to current keyboard layout ;)

            trace(event.text);
        }
    }
}
