jquery实现蛇形时间轴

首先，可以使用HTML和CSS来创建蛇形时间轴的基本结构和样式，然后使用jQuery来操纵它。

下面是一个简单的示例代码：

HTML结构：

<div class="timeline">
  <div class="timeline-item">
    <div class="timeline-content">
      <h2>2010</h2>
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
    </div>
  </div>
  <div class="timeline-item">
    <div class="timeline-content">
      <h2>2012</h2>
      <p>Donec ut metus eget ligula blandit commodo.</p>
    </div>
  </div>
  <div class="timeline-item">
    <div class="timeline-content">
      <h2>2015</h2>
      <p>Suspendisse potenti. Nulla facilisi.</p>
    </div>
  </div>
  <div class="timeline-item">
    <div class="timeline-content">
      <h2>2018</h2>
      <p>Phasellus vel semper velit, eget varius ex.</p>
    </div>
  </div>
</div>

CSS样式：

.timeline {
  position: relative;
  margin: 0 auto;
  padding: 0;
  list-style: none;
  max-width: 800px;
}
.timeline:before {
  content: '';
  position: absolute;
  top: 0;
  bottom: 0;
  width: 2px;
  background-color: #ddd;
  left: 50%;
  margin-left: -1px;
}
.timeline-item {
  margin-bottom: 50px;
  position: relative;
}
.timeline-item:before,
.timeline-item:after {
  content: '';
  display: table;
}
.timeline-item:after {
  clear: both;
}
.timeline-item:last-child {
  margin-bottom: 0;
}
.timeline-content {
  position: relative;
  width: 50%;
  padding: 20px;
  background-color: #f7f7f7;
  border-radius: 8px;
}
.timeline-content h2 {
  margin-top: 0;
}
.timeline-content p {
  margin: 0;
}

/* 反转偶数项 */
.timeline-item:nth-child(even) .timeline-content {
  float: right;
}
.timeline-item:nth-child(even) .timeline-content:before {
  right: auto;
  left: -15px;
  border-width: 8px 0 8px 15px;
  border-color: transparent transparent transparent #f7f7f7;
}
.timeline-item:nth-child(even) .timeline-content:after {
  right: auto;
  left: 0px;
  border-width: 7px 0 7px 15px;
  border-color: transparent transparent transparent #ddd;
}

jQuery代码：

$(document).ready(function() {
  var items = $('.timeline-item');
  var heights = [];

  // 获取所有项目的高度
  items.each(function() {
    var height = $(this).outerHeight();
    heights.push(height);
  });

  // 设置所有项目的高度
  items.each(function(i) {
    var height = heights[i];
    $(this).css('height', height);
  });
});

这段代码将获取所有时间轴项目的高度，并将其应用到每个项目上，从而创建一个蛇形时间轴的效果。
