单击链接时如何显示div

标签： javascript jquery html css

我有一个类yes的链接，我想在点击链接时显示带有类名div的{​​{1}}。我编写了下面的代码，但它不起作用，点击时不显示任何内容。这是我的片段：

(box)
$('.yes').on('click', function(e){  e.preventDefault();  $(this).siblings('.box').toggleClass('active');})
.box {
  display: none;
  line-height: 100px;
  background: #ccc;
  border: 1px solid #444;
  text-align: center;
  -webkit-transform: scale(0);
          transform: scale(0);
  opacity: 0;
  -webkit-transition: opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
  transition: opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
  transition: transform .3s ease-in-out, opacity .3s ease-in-out;
  transition: transform .3s ease-in-out, opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
}
.box.active {
  display: block;
  -webkit-transform: scale(1);
          transform: scale(1);
  opacity: 1;
}

.box.active.good {
  -webkit-animation: anim .3s ease-in-out;
          animation: anim .3s ease-in-out;
}

@-webkit-keyframes anim {
  0% {
    display: none;
    opacity: 0;
  }
  1% {
    display: block;
    opacity: 0;
    -webkit-transform: scale(0);
            transform: scale(0);
  }
  100% {
    opacity: 1;
    -webkit-transform: scale(1);
            transform: scale(1);
  }
}

@keyframes anim {

如果您只有一个方框，为什么不直接使用班级选择器$('.box')。

$('.box').toggleClass('active');

如果您在每个ul之后有多个.box，请使用.parents() 

$(this).parents('ul').next().toggleClass('active');

＆＃13;
＆＃13; 
$('.yes').on('click', function(e){  
  e.preventDefault(); 
  $('.box').toggleClass('active');
  //$(this).parents('ul').next().toggleClass('active');
})
＆＃13; 
.box {
  display: none;
  line-height: 100px;
  background: #ccc;
  border: 1px solid #444;
  text-align: center;
  -webkit-transform: scale(0);
          transform: scale(0);
  opacity: 0;
  -webkit-transition: opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
  transition: opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
  transition: transform .3s ease-in-out, opacity .3s ease-in-out;
  transition: transform .3s ease-in-out, opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
}
.box.active {
  display: block;
  -webkit-transform: scale(1);
          transform: scale(1);
  opacity: 1;
}

.box.active.good {
  -webkit-animation: anim .3s ease-in-out;
          animation: anim .3s ease-in-out;
}

@-webkit-keyframes anim {
  0% {
    display: none;
    opacity: 0;
  }
  1% {
    display: block;
    opacity: 0;
    -webkit-transform: scale(0);
            transform: scale(0);
  }
  100% {
    opacity: 1;
    -webkit-transform: scale(1);
            transform: scale(1);
  }

它不是你的锚标记的直接兄弟。它是＆＃34; ul＆＃34;

的兄弟姐妹

＆＃13;

$('.yes').on('click', function(e){  e.preventDefault();  $(this).parents("ul").siblings('.box').toggleClass('active');})

答案 2 :(得分：0)

这是因为你的<a href="#tab-1" class="yes">元素没有兄弟姐妹。 $(this).siblings没有返回任何内容。

要解决此问题，您可以使用此替代javascript：

$('.yes').on('click', function(event) {
  event.preventDefault();
  $(this).parents("ul").siblings('.box').toggleClass('active');
});

展开演示代码段：

＆＃13;
＆＃13; 
$('.yes').on('click', function(event) {
  event.preventDefault();
  $(this).parents("ul").siblings('.box').toggleClass('active');
});
＆＃13; 
.box {
  display: none;
  line-height: 100px;
  background: #ccc;
  border: 1px solid #444;
  text-align: center;
  -webkit-transform: scale(0);
          transform: scale(0);
  opacity: 0;
  -webkit-transition: opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
  transition: opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
  transition: transform .3s ease-in-out, opacity .3s ease-in-out;
  transition: transform .3s ease-in-out, opacity .3s ease-in-out, -webkit-transform .3s ease-in-out;
}
.box.active {
  display: block;
  -webkit-transform: scale(1);
          transform: scale(1);
  opacity: 1;
}

.box.active.good {
  -webkit-animation: anim .3s ease-in-out;
          animation: anim .3s ease-in-out;
}

@-webkit-keyframes anim {
  0% {
    display: none;
    opacity: 0;
  }
  1% {
    display: block;
    opacity: 0;
    -webkit-transform: scale(0);
            transform: scale(0);
  }
  100% {
    opacity: 1;
    -webkit-transform: scale(1);
            transform: scale(1);
  }
}

@keyframes anim {
  0% {
    display: none;
    opacity: 0;
  }
  1% {
    display: block;
    opacity: 0;
    -webkit-transform: scale(0);
            transform: scale(0);
  }
  100% {
    opacity: 1;
    -webkit-transform: scale(1);
            transform: scale(1);

</body>
</html>
＆＃13;
＆＃13;
＆＃13;

但基本上，你的锚标签和你的盒子不是兄弟姐妹，这可以通过缩进显示：

<ul>
  <li><a href="#tab-1" class="yes">Show Box</a></li>
</ul>
<div class="box good" style="width:200px; height:200px;border:1px solid red;"></div>

兄弟姐妹需要处于同一水平。也许这个图表可以帮助你更好地理解兄弟姐妹是什么：

试试这个：

$('.yes').on('click', function(e){  
e.preventDefault(); 
$(this).parents("ul").siblings('.box').toggleClass('active');
return false;
})

return false表示链接不起作用，但onclick中的代码可以正常工作。

答案 4 :(得分：0)

这是因为在你的HTML中，课程是“是”＆＃39;没有兄弟姐妹。

使用此功能直接显示＆＃39;框＆＃39;类

$('.yes').on('click', function(e){  
   e.preventDefault(); 
   $('.box').toggleClass('active');
 });

你走错了路。请像
