如何在元素隐藏时禁用accesskey？

Answer 1

我认为没有办法禁用accesskey，您只需根据需要add / remove

if(!$('div').is(":visible"))
{
   $('div').removeAttr('accesskey');
}
else
{
   $('div').attr('accesskey', '1');
}

if(!$('div').is(":visible"))
{
  $('div').removeAttr('accesskey');
}
else
{
  $('div').attr('accesskey', '1');
}
    

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div hidden accesskey="1">
    Some things...
</div>

<p>
  Focus on me and then 
  </br>
  <b>press [Alt + 1] please!</b>
</p>

Answer 2

您可以检查div事件中的hidden是否为click：

$('div').click(function(event) {

  if (!$(this).is(':hidden')) {
    alert("Shortcut worked although element was hidden!");
  } else {
    event.preventDefault();
  }

});
