我想知道是否有人可以阐明我的代码？它似乎可以正常工作而没有任何错误，但某些按钮不起作用。（即进入投资菜单，然后输入“查看投资组合”、“投资”和“确定”按钮将不起作用。）

这是整个代码。

尽管提供“所有代码”很有用，但在这种情况下，您混淆了您正在处理的核心问题。在其中任何地方都找不到“查看投资组合”或“投资”字样，并且对于所有其他按钮注册，需要逐行阅读以查看您是否输入了按钮。

此外，由于这些界面元素似乎不是动态创建的（而是使用 Flash IDE，因此存在于看不见的库中），我们无法判断正确的变量名称应该是什么。

简明扼要。提供尽可能少的代码来重现问题。

简化。每当您看到重复的代码模式时，这可能意味着您可以使用函数或循环来减少。

所有这些按钮都在为“(MouseEvent.CLICK, menu)”注册或取消注册。例如，您可以使用循环更快地完成此操作...

var buttons:Array = [
    bg.ok,
    bg.menubtn,
    bg.Balinq,
    bg.Transinq,
    bg.Fintrxns,
    bg.invest,
    bg.others,
    bg.passchange
]

for (var btn in buttons) {
    btn.addEventListener(MouseEvent.CLICK, menu);
}

现在，当您需要对所有这些按钮进行操作时，您只需查看一个位置。

单击按钮时，您正在测试对象的名称并取消注册它。您可以避免此测试并简单地取消注册目标。因此，而不是这个：

if (m.target.name == "menubtn") {
    bg.menubtn.removeEventListener(MouseEvent.CLICK, menu);
}

做就是了：

m.target.removeEventListener(MouseEvent.CLICK, menu);

另一种简化代码的方法是使用switch 运算符。像这样的方法...

if (m.target.name == "viewport") {
    // do a
}
if (m.target.name == "viewhist") {
    // do b
}
if (m.target.name == "subscribe") {
    // do c
}

可以变成...

switch (m.target.name) {
    case "viewport": // do a
        break;
    case "viewhist": // do b
        break;
    case "subscribe": // do c
        break;
}

当您知道您总是比较以测试相同的变量时，这很方便。

最后，可重用代码意味着轻量级代码易于维护，减少繁重的工作，并使文档更具可读性。有了你在这里所做的，我相当有信心你可以把它从 650 行代码减少到大约 50 行代码。
