Is there any good reason why most rails developers use observe_field when they want trigger specific action when text input box is changed, rather then using onkeydown? I would expect, that in most of the cases using observe_field results much more code generated than just using native hook onkeydown.
大多数rails开发人员在更改文本输入框时想要触发特定操作时使用observe_field，而不是使用onkeydown是否有任何理由？我希望，在大多数情况下，使用observe_field会产生比仅使用本机钩子onkeydown更多的代码。

I think it's just a convenient way rails supplied for the person who doesn't know about javascript, or who doesn't want to write another piece of JavaScript code.
我认为这只是为不了解javascript的人提供的一种方便的方式，或者谁不想编写另一段JavaScript代码。
