"上拉查看图文详情"是一种常见的用户界面交互模式,通常用于移动应用或网页中。用户在浏览列表内容时,通过向上滑动屏幕来加载更多详细信息或进入下一篇文章/商品详情页。
以下是一个简单的JavaScript示例,展示如何实现上拉查看图文详情的功能:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>上拉查看图文详情</title>
<style>
.item {
height: 200px;
border: 1px solid #ccc;
margin: 10px;
display: flex;
align-items: center;
justify-content: center;
font-size: 20px;
}
.detail {
display: none;
padding: 20px;
background-color: #f9f9f9;
}
</style>
</head>
<body>
<div id="container">
<div class="item" data-target="detail1">Item 1</div>
<div class="item" data-target="detail2">Item 2</div>
<div class="item" data-target="detail3">Item 3</div>
<!-- 更多项 -->
</div>
<div id="detail1" class="detail">
<h2>Detail for Item 1</h2>
<p>This is the detailed information for Item 1.</p>
</div>
<div id="detail2" class="detail">
<h2>Detail for Item 2</h2>
<p>This is the detailed information for Item 2.</p>
</div>
<div id="detail3" class="detail">
<h2>Detail for Item 3</h2>
<p>This is the detailed information for Item 3.</p>
</div>
<script>
document.addEventListener('DOMContentLoaded', function() {
const items = document.querySelectorAll('.item');
items.forEach(item => {
item.addEventListener('click', function() {
const target = this.getAttribute('data-target');
const detail = document.getElementById(target);
detail.style.display = detail.style.display === 'block' ? 'none' : 'block';
});
});
});
</script>
</body>
</html>
