滑块效果不起作用

Question

我正在尝试在我的滑块上获得漂亮的幻灯片效果（从左到右）。但它不适用于过渡和 jQuery。

我的代码有问题吗？

$(document).ready(function() {
  $('.weiter').click(function() {
    if ($('.eins').hasClass('active')) {
      $('.eins').removeClass('active');
      $('.zwei').addClass('active');
    } else if ($('.zwei').hasClass('active')) {
      $('.zwei').removeClass('active');
      $('.eins').addClass('active');
    }
  });
});

header {
  height: 250px;
  width: 100%;
  display: inline-block;
  margin-bottom: 20px;
}
header section.eins {
  background: url("http://www.petakids.com/wp-content/uploads/2015/07/sheep-and-lambs-in-field.jpg");
}
header section.zwei {
  background: url("https://aos.iacpublishinglabs.com/question/aq/700px-394px/long-sheep-pregnant_1b7dbe4ddad4dd1.jpg?domain=cx.aos.ask.com");
}
header section {
  height: 0;
  visibility: hidden;
  width: 0;
  float: left;
}
header section.active {
  float: left;
  height: 100%;
  width: 100%;
  visibility: visible;
}
.weiter {
  display: block;
  cursor: pointer;
  height: 50px;
  background: red;
  width: 50px;
}

您的代码中缺少滑块动画。我可以使用元素的位置属性添加一个简单的幻灯片过渡。

参考代码：

$(document).ready(function() {
  $('.weiter').click(function() {
    if ($('.eins').hasClass('active')) {
      $('.eins').removeClass('active');
      $('.zwei').addClass('active');
    } else if ($('.zwei').hasClass('active')) {
      $('.zwei').removeClass('active');
      $('.eins').addClass('active');
    }
  });
});

header section.eins {

}

  background: url("https://aos.iacpublishinglabs.com/question/aq/700px-394px/long-sheep-pregnant_1b7dbe4ddad4dd1.jpg?domain=cx.aos.ask.com");
}
header section {

  float: left;
  position: relative;

  transition: all .3s;
}
header section.active {
  float: left;
  position: relative;

  height: 100%;
  width: 100%;

}
.weiter {
  display: block;
  cursor: pointer;
