Question

使用箭头浏览动作脚本 swf 的最佳方式是什么？

Answer 1

设置 TextInput 的 tabIndex 属性。这应该允许您通过选项卡浏览表单。

不建议覆盖箭头键的默认功能，因为它们用于移动 textInput 中的文本插入点

至于 Enter，您必须监听 keyUp 事件，如果检测到 Enter 键，则移动到下一个字段。

//add this eventlistener for each textbox (through a loop or manually)
t.addEventListener(KeyboardEvent.KEY_UP, k);

//The event handler
protected function k(e:KeyboardEvent):void {
    if(e.keyCode==Keyboard.ENTER) {
         focusManager.getNextFocusManagerComponent().setFocus();
    }
}

编辑

对于Flash CS5，此代码应该有效：

import flash.events.KeyboardEvent;
import fl.managers.FocusManager; 
import flash.display.InteractiveObject; 
import fl.managers.IFocusManagerComponent;
import fl.managers.IFocusManager;

t1.addEventListener(KeyboardEvent.KEY_UP, k);
t1.tabIndex=1;
t2.tabIndex=2;

var fm:FocusManager=new FocusManager(this);

t1.tabEnabled=true;
t2.tabEnabled=true;

function k(e:KeyboardEvent):void {
    if(e.keyCode==Keyboard.ENTER) {
         var fx:InteractiveObject = fm.getNextFocusManagerComponent();
         fm.setFocus(fx);
    }
}

重要：首先将一个组件从“用户界面”组拖到舞台上并将其删除。这应该将库中的所有必需组件准备好供您使用

将

for(var i:int=0; i < textbox.length; i++) {
        //textbox[i].buttonMode = true;
        //box[i].addEventListener(MouseEvent.CLICK, myclick_ftn);
        //box[i].addEventListener(FocusEvent.FOCUS_IN,textInputHandler);
        //box[i].addEventListener(FocusEvent.FOCUS_OUT,textInputHandlerOut);
        textbox[i].restrict = "0-9";
        textbox[i].addEventListener(KeyboardEvent.KEY_UP, k);
        textbox[i].tabIndex=i;
        //t2.tabIndex=2;

        //textbox[i].tabEnabled=true;

                var fm:FocusManager=new FocusManager(this);


        function k(e:KeyboardEvent):void {
            if(e.keyCode==Keyboard.ENTER) {
                var fx:InteractiveObject = fm.getNextFocusManagerComponent();
                fm.setFocus(fx);
    }
}
        //t2.tabEnabled=true;
}

代码更改为：

var fm:FocusManager=new FocusManager(this);


function k(e:KeyboardEvent):void {
    if(e.keyCode==Keyboard.ENTER) {
        var fx:InteractiveObject = fm.getNextFocusManagerComponent();
        fm.setFocus(fx);
    }
}

for(var i:int=0; i < textbox.length; i++) {
        //textbox[i].buttonMode = true;
        //box[i].addEventListener(MouseEvent.CLICK, myclick_ftn);
        //box[i].addEventListener(FocusEvent.FOCUS_IN,textInputHandler);
        //box[i].addEventListener(FocusEvent.FOCUS_OUT,textInputHandlerOut);
        textbox[i].restrict = "0-9";
        textbox[i].addEventListener(KeyboardEvent.KEY_UP, k);
        textbox[i].tabIndex=i;
        //t2.tabIndex=2;

        //textbox[i].tabEnabled=true; 

}
