这是之前项目的延续，参见此处（选择/突出显示行和更改同一行中突出显示的文本字段的值）。User Scription 非常有用。谢谢！
让这个工作按照我需要的方式工作的下一个业务线是让菜单中的第四个选项可以通过 onClick 编辑，但方式与上面的选项不同，因为它需要不同的选项集。此行的选项仅涉及更改文本，不涉及任何数字。我已经想出了如何通过 onClick 从 stackoverflow 上的另一个线程更改文本，但我现在需要将其集成到我现有的设计中。我已经让 Plunker 继续前进（下面的链接）。正如你所看到的，我可以使用我放在包装器下方的小按钮来更改第四个选项行的文本以进行测试。我需要这个只能在突出显示时进行调整，并且使用现有的 D-pad 左/右箭头 - 与其他行相同。显然，值也需要根据按下的按钮来增加和减少。文本短语从一个地方开始，在另一个地方结束，因此 onClick 事件需要按顺序循环它们。
为了进一步复杂化或添加到项目中，我需要能够让用户向下滚动到“更多↓”选项，然后进入一个全新的选项集/窗口。我想我们会使用类似于 CSS 溢出的东西：属性，但是当将它与所有这些代码结合起来时，我不确定如何实现它。
一如既往，任何帮助表示赞赏！

更新 2013-09-27
我已经更新了我的代码并且接近了，但我被困在这里：http ://plnkr.co/edit/iZOJAx8BmKVMX8zII4kk?p=preview 。我正在和第四排打架。它只是不太正常。当我用键盘调整数字时，我可以获得要更改的值和要显示的正确文本，但它不适用于从 D-pad 更改为值的 onClick。当 D-pad 执行此操作时，文本不会发生任何变化。我认为这与代码中的“keyup”调用有关，但我放在那里的任何东西（onBlur、onFocus 等）似乎都不起作用。
我目前的设置远非优雅，所以任何关于如何清理混乱的建议都将不胜感激。我确信有一种更简单的方法可以完成同样的事情，但这是我使用我所拥有的知识和想到的想法所构想的。完整的代码可以在下面看到。请原谅相关链接，因为这是从我的实际文件中复制的（我现在开始整理界面，所以我对许多元素使用图形）。
