JavaScript 表格内信息向上滚动是一种常见的网页动画效果,用于展示表格中的数据,尤其是在数据量较大且用户希望在不滚动整个页面的情况下查看所有数据时非常有用。
setInterval
)不断改变表格内容的垂直位置,从而实现滚动效果。position: relative
或 position: absolute
来控制元素的移动。以下是一个简单的单行向上滚动的示例:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Table Scroll Example</title>
<style>
#scrollTable {
width: 100%;
overflow: hidden;
position: relative;
}
#scrollContent {
position: absolute;
white-space: nowrap;
}
</style>
</head>
<body>
<div id="scrollTable">
<div id="scrollContent">
<span>Row 1: Data 1</span><br>
<span>Row 2: Data 2</span><br>
<span>Row 3: Data 3</span><br>
<!-- Add more rows as needed -->
</div>
</div>
<script>
const content = document.getElementById('scrollContent');
let scrollPosition = 0;
const scrollSpeed = 1; // Adjust speed as needed
function scrollTable() {
scrollPosition -= scrollSpeed;
content.style.top = scrollPosition + 'px';
// Reset position when content reaches the end
if (-scrollPosition >= content.clientHeight) {
scrollPosition = document.getElementById('scrollTable').clientHeight;
}
}
setInterval(scrollTable, 50); // Adjust interval as needed
</script>
</body>
</html>
requestAnimationFrame
替代 setInterval
。通过以上方法,可以有效地实现和控制表格内容的向上滚动效果。
