第一次在这里发帖。我使用一个循环来创建3个按钮，但我的问题是分配的按钮操作到每个按钮。我的按钮侦听/动作code仅适用于创建的最后一个按钮：（

我想由我给他们（$ navButton.name =按钮+ I），但扔了一个未定义的错误为Button1的名称为目标的按钮。

任何帮助将是AP preciated，我是一个AS3小白：（

 函数createNav（）{

    对于（VAR我：数量= 0; I＆LT; myXMLArray.length;我++）
    {
    $ navButton =新NavButton（）;
    $ navButton.name =按钮+我;
    $ navButton.x = I *（SIZE +间隔）;
    $ navButton.y = 179;
    的addChild（$ navButton）;
    跟踪（$ navButton.name =+ $ navButton.name）;
    跟踪（按钮1 =+按钮1）;

        //试图给3个按钮的简单变换/点击动作：

    $ navButton.buttonMode = $ navButton.buttonMode = TRUE;
    $ navButton.addEventListener（侦听MouseEvent.MOUSE_UP，navAction）;
    $ navButton.addEventListener（MouseEvent.ROLL_OVER，函数（）{$ navButton.nextFrame（）;}）;
    $ navButton.addEventListener（MouseEvent.ROLL_OUT，函数（）{$ navButton prevFrame（）;}）;


        //以为我可以控制通过调用$ navButton.name
    //button1.addEventListener(MouseEvent.MOUSE_UP，navAction）;
    //button1.addEventListener(MouseEvent.ROLL_OVER，函数（）{button1.nextFrame（）;}）;
    //button1.addEventListener(MouseEvent.ROLL_OUT，函数（）{按钮1 prevFrame（）;}）;


    / * VAR traceText：文本字段=新的TextField（）;
    traceText.defaultTextFormat = A12;
    traceText.x = I *（SIZE +间隔）;
    traceText.y = 181;
    traceText.width = 116;
    traceText.height = 20;
    traceText.text = myXMLArray [I] .ID;
    的addChild（traceText）; * /
    }

}

功能navAction（）
{

    跟踪（点击）;
}
 

解决方案

我想补充的按钮到一个数组广告获得这样：

在循环外部：

  VAR按钮：数组= []
 

在循环：

  buttons.push（navButton）
按钮[1] .addEventListener（侦听MouseEvent.MOUSE_UP，navAction）;
 

本应在循环外做，如果你想自定义的功能添加到一个按钮。命名对象不给你一个对象，在实例的名称。要访问它，你有以上，你可能需要使用：

  VAR按钮1：NavButton
 

这将允许您访问，你所做的一切。使用name属性，你可以使用的东西，如：

 如果（navButton.name ==按钮1）
    navButton.addEventListener（Event.BLAHBLAH，DoStuff）;
 

我强烈建议不要使用匿名函数作为事件监听器。而是使用命名函数和事件的目标属性：

 函数handleButtonClick（事件：MouseEvent）方法：无效
{
    VAR按钮：NavButton将event.target =为NavButton;
    如果（按钮）
        button.nextFrame（）
}
 

虽然它可能（可能会）的匿名函数的功能，这将是这么容易得多，如果你使用的命名函数进行调试。

顺便说一句，使用$您的增值经销商一般在AS3不好的形式。 这里的Flex SDK的标准，这是极好的约定所有的AS3编程。

first time posting here. I'm using a loop to create 3 buttons, but my problem is assigning the button actions to each button. My button listener/action code only works on the last button created :(

I tried to target buttons by the name that I gave them ($navButton.name = "button" + i) but that threw up an undefined error for button1.

Any help would be appreciated, I'm an AS3 noob :"(

function createNav(){

    for (var i:Number = 0; i < myXMLArray.length; i++)
    {
    	$navButton = new NavButton();
    	$navButton.name = "button" +i;
    	$navButton.x = i * (SIZE + SPACING);
    	$navButton.y = 179;
    	addChild($navButton);
    	trace("$navButton.name = "+$navButton.name);
    	trace("button 1 = "+button1);

        //trying to give the 3 buttons a simple rollover/click action:

    	$navButton.buttonMode = $navButton.buttonMode = true;
    	$navButton.addEventListener(MouseEvent.MOUSE_UP, navAction);
    	$navButton.addEventListener(MouseEvent.ROLL_OVER, function() {$navButton.nextFrame();});
    	$navButton.addEventListener(MouseEvent.ROLL_OUT, function() {$navButton.prevFrame();});


        //thought I could control via calling the $navButton.name
    	//button1.addEventListener(MouseEvent.MOUSE_UP, navAction);
    	//button1.addEventListener(MouseEvent.ROLL_OVER, function() {button1.nextFrame();});
    	//button1.addEventListener(MouseEvent.ROLL_OUT, function() {button1.prevFrame();});


    	/*var traceText:TextField = new TextField();
    	traceText.defaultTextFormat = a12;
    	traceText.x = i * (SIZE + SPACING);
    	traceText.y = 181;
    	traceText.width = 116;
    	traceText.height = 20;
    	traceText.text = myXMLArray[i].id;
    	addChild(traceText);*/
    }

}

function navAction()
{

    trace("click");
}

I would add the buttons to an array ad access as such:

outside of the loop:

var buttons:Array = []

in the loop:

buttons.push(navButton)
buttons[1].addEventListener(MouseEvent.MOUSE_UP, navAction);

This should be done outside of the loop if you are trying to add custom functionality to a single button. Naming the object doesn't give you an object with the instance name. To access it as you have above, you'd need to use:

var button1:NavButton

which would allow you to access as you have done. Using the name property you could use something such as:

if(navButton.name == "button1")
    navButton.addEventListener(Event.BLAHBLAH, DoStuff);

I strongly recommend against using anonymous functions as your event listeners. Instead use named functions and the target property of the event:

function handleButtonClick(event:MouseEvent):void
{
    var button:NavButton = event.target as NavButton;
    if(button)
        button.nextFrame()
}

While it might (probably will) function with the anonymous functions, it will be so much easier to debug if you use named functions.

As an aside, using the $ for your vars is generally bad form in AS3. Here's the Flex SDK Standards, which are excellent conventions for all AS3 programming.
