有没有任何其他addEventListener（）方法我可以替换keyup？

with no success. Is there any other addEventListener() method I can replace keyup with?

是的，模糊

如果您要添加keydown < div> 元素上的事件，您可以执行以下操作：

If you would like to add keydown events on a <div> element, you can do the following:

首先， tabindex属性：

First, you need to set the tabindex attribute:

<div id="a-div" tabindex="1" />

然后，
（2）绑定到键：

Then, (2) Bind to keydown:

 $('#mydiv').bind('keydown', function(event) {
    //console.log(event.keyCode);
 });

如果你希望你的div从一开始就是专注：

If you would like your div to be "focused" from the start:

$(function() {
   $('#mydiv').focus();
});
