单击按钮时隐藏和显示

Question

我有这样的代码 (HTML/CSS/JS):

$('.subnav__right li a').click(function(e){
     e.preventDefault();

     var $this = $(this).parent().find('.subnav__hover');
     $('.subnav__hover').not($this).hide();
     
     $this.toggle();
     
 });

 $(document).mouseup(function (e)
 {
     var container = $('.subnav__hover');

     if (!container.is(e.target) && container.has(e.target).length === 0)
     {
         container.hide();
     }
 });

.subnav__hover{
  display: none;
 }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="subnav__right">
  <ul>
    <li class="subnav__notif">
      <a href="#" class="np-ico-notification">Link 1</a>
      <div class="subnav__hover"> CONTENT 1</div>
    </li>
    <li class="subnav__caremail">
      <a href="#" class="np-ico-caremail">Link 2</a>
      <div class="subnav__hover"> CONTENT 2</div>
    </li>
    <li class="subnav__profile">
      <a href="#">Link 3</a>
      <div class="subnav__hover"> CONTENT 3</div>
    </li>
  </ul>
</div>

问题是切换功能（当我单击 .subnav__right li a 时）不起作用。但是点击外面可以隐藏.subnav__hover.

知道如何使切换起作用吗？

Answer 1

我觉得点击功能应该是：

$('.subnav__right ul li a').click(function(e){
    e.preventDefault();

    var $this = $(this).parent().find('.subnav__hover');
    $('.subnav__hover').not($this).hide();

    $this.toggle();
});

Answer 2

将它绑定到回调或使用它。

var that = this;
$('.subnav__right li a').click(function(e){
    e.preventDefault();

    var $this = $(that).parent().find('.subnav__hover');
    $('.subnav__hover').not($this).hide();

    $this.toggle();

});

Answer 3

也许删除 not ! 运算符可以解决您的问题（我猜），因此您的 JS 代码的第二部分将是：

$(document).mouseup(function (e)
{
    var container = $('.subnav__hover');

    if (container.is(e.target) && container.has(e.target).length === 0)
    {
        container.hide();
    }
});

Answer 4

使用这个：

$(document).mouseup(function (e)
{
     var container = $('.subnav__hover:visible');
        var clickedObj = $(e.target).next('.subnav__hover');
     if (!container.is(clickedObj) && container.has(e.target).length === 0)
     {
         container.hide();
     }
});

我做了一些小改动，比如更改文档事件并添加 e.stopPropagation()。请检查。

$('.subnav__right li a').click(function(e){
     e.preventDefault();
e.stopPropagation();
     var $this = $(this).parent().find('.subnav__hover');
     $('.subnav__hover').not($this).hide();
     
     $this.toggle();
     
 });

 $(document).click(function (e)
 {
     var container = $('.subnav__hover');

     if (!container.is(e.target) && container.has(e.target).length === 0)
     {
         container.hide();
     }
 });

.subnav__hover{
  display: none;
 }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="subnav__right">
  <ul>
    <li class="subnav__notif">
      <a href="#" class="np-ico-notification">Link 1</a>
      <div class="subnav__hover"> CONTENT 1</div>
    </li>
    <li class="subnav__caremail">
      <a href="#" class="np-ico-caremail">Link 2</a>
      <div class="subnav__hover"> CONTENT 2</div>
    </li>
    <li class="subnav__profile">
      <a href="#">Link 3</a>
      <div class="subnav__hover"> CONTENT 3</div>
    </li>
  </ul>
</div>
