Jquery parents 不工作

Question

我有一个关于 jquery parents 的问题。

我从 codepen.io

创建了这个 DEMO

在这个演示中你可以看到有一棵树 link 显示 div, 显示 div2 和 显示 div3。如果你点击 Show div 然后 jquery 代码将打开 .popup 和 .openingdiv 但其他 link 不工作相同的代码。有人可以帮我吗？

$(document).ready(function() {
$('.click').click(function (e) {
    e.preventDefault();
   $('.popup').animate({'opacity':'.50'}, 300, 'linear');
   $('.popup').css('display', 'block');
   $(this).parent().next('.openingdiv').toggleClass('height');
     $(this).toggleClass('zindex');

  $('.closediv a').click(function(e){
    e.preventDefault();
    $('.popup').animate({'opacity':'.50'}, 500, 'linear');
   $('.popup').css('display', 'none');
    $(this).closest('.openingdiv').removeClass('height');
  });
})
  $('.click2').click(function (e) {
    e.preventDefault();
   $('.popup').animate({'opacity':'.50'}, 300, 'linear');
   $('.popup').css('display', 'block');
   $(this).parent().next('.openingdiv2').toggleClass('height');
     $(this).toggleClass('zindex');

  $('.closediv2 a').click(function(e){
    e.preventDefault();
    $('.popup').animate({'opacity':'.50'}, 500, 'linear');
   $('.popup').css('display', 'none');
    $(this).closest('.openingdiv2').removeClass('height');
  });
})

});

HTML

<div class="container">
  <div class="click"><a href="#">Show Div</a></div>
  <div class="click2"><a href="#">Show Div2</a></div>
  <div class="click3"><a href="#">Show Div3</a></div>
</div>
<div class="openingdiv">
  <div class="closediv"><a href="#">close</a></div>
</div>
<div class="openingdiv2">
  <div class="closediv2"><a href="#">close2</a></div>
</div>
<div class="openingdiv3">
  <div class="closediv3"><a href="#">close3</a></div>
</div>

<div class="popup"></div>

Answer 1

因为你用过

$('.popup').css('display', 'block');

您可以使用 'none' 来激活其他链接或完全以另一种方式编写吗？

Answer 2

请在此处检查这支笔。它使用 .on() 绑定事件

  <div class="container">
    <div class="click button" data-opener="1"><a href="#">Show Div</a></div>

    <div class="click3 button" data-opener="3"><a href="#">Show Div3</a></div>
  </div>
  <div class="openingdiv1 opener">
    <div class="closediv closer"><a href="#">close</a></div>
  </div>
  <div class="openingdiv2 opener">
    <div class="closediv closer"><a href="#">close2</a></div>
