html - 模态关闭时页面滚动到顶部

Question

我已经实现了一个模式，但我不希望页面在模式关闭时滚动到顶部。它会自动执行此操作。是否有管理我缺少的以下代码的代码？感谢您的帮助!

HTML

<a href="#target-content" id="button">Open A Modal</a>

<div id="target-content">
  <a href="#" class="close"></a>
  <div id="target-inner">
    <h2>Modal Heading</h2>
    <p>Modal Content</p>
  </div>
</div>

CSS

#target-content {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  pointer-events: none;
  opacity: 0;
  -webkit-transition: opacity 200ms;
  transition: opacity 200ms;
}

#target-content:target {
  pointer-events: all;
  opacity: 1;
}

#target-content #target-inner {
  position: absolute;
  display: block;
  padding: 48px;
  line-height: 1.8;
  width: 70%;
  top: 50%;
  left: 50%;
  -webkit-transform: translateX(-50%) translateY(-50%);
  -ms-transform: translateX(-50%) translateY(-50%);
  transform: translateX(-50%) translateY(-50%);
  box-shadow: 0px 12px 24px rgba(0, 0, 0, 0.2);
  background: white;
  color: #34495E;
}

#target-content #target-inner h2 { margin-top: 0; }

#target-content #target-inner code { font-weight: bold; }

#target-content a.close {
  content: "";
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background-color: #34495E;
  opacity: 0.5;
  -webkit-transition: opacity 200ms;
  transition: opacity 200ms;
}

#target-content a.close:hover { opacity: 0.4; }

Answer 1

href 属性中的# 会将您的页面发送到顶部。

<a href="#" class="close"></a> <!-- moves scroll position to top of page -->

一种解决方案是将 # 替换为您希望页面转到或停留的特定 ID。

试试这个:

<a href="#target-content" class="close"></a>
