我在检测文本框上的输入键事件时遇到问题。我似乎不能使用这个

$("#serial").keyup(function(e) {
    if(e.which == 13) {
...
   }
});

但是如果我使用它，可以检测到 keyup 事件

$(document).keyup(function(e) {
    if(e.which == 13) {
...
   }
});

这有点尴尬，因为无论光标位置如何，如果按下输入键都会触发事件。希望有人会在这方面有一个指针。谢谢：D

我认为在网站上包含这些插件对我来说是公平的：

事情是..我不知道是否有任何这些可以解除 keyup 事件的绑定
