Question

使用箭头浏览actionscript swf的最佳方法是什么？

Answer 1

设置tabIndex的{​​{1}}属性。这应该允许您在表单中进行制表。

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

至于enter，您必须侦听keyUp事件，如果检测到回车键，则移至下一个字段。

TextInput

修改

对于Flash CS5，此代码应该有效：

//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();
    }
}

重要：首先将组件从“用户界面”组拖到舞台上并将其删除。这应该将库中所有必需的组件准备好供您使用

更改

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);
    }
}

在您的代码中：

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;
}
