网页右下角弹出视频广告的JavaScript代码通常涉及到DOM操作、事件监听以及定时器等概念。以下是一个简单的示例代码,用于在网页右下角弹出一个视频广告:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Video Ad Example</title>
<style>
#videoAd {
position: fixed;
right: 10px;
bottom: 10px;
width: 300px;
height: 200px;
z-index: 1000;
}
</style>
</head>
<body>
<div id="videoAd">
<video id="adVideo" controls autoplay muted>
<source src="path_to_your_video.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<button id="closeAd">Close</button>
</div>
<script>
document.addEventListener('DOMContentLoaded', function() {
const adVideo = document.getElementById('adVideo');
const closeAdButton = document.getElementById('closeAd');
// Show the ad after 5 seconds
setTimeout(() => {
document.getElementById('videoAd').style.display = 'block';
}, 5000);
// Close the ad when the close button is clicked
closeAdButton.addEventListener('click', function() {
document.getElementById('videoAd').style.display = 'none';
});
});
</script>
</body>
</html>
通过上述代码和解释,你可以实现一个简单的右下角视频广告,并了解其相关的基础概念和应用场景。
