我想制作一个 JavaScript(JavaScript 动画)作为我的项目网站的预加载器。
大致如下: http://soulwire.github.io/Plasmatic-Isosurface/
我希望它首先运行，直到下载页面的元素，之后它应该关闭并显示完全加载的页面
这可能吗？
谢谢
这是我想要测试的示例 HTML 代码
<!DOCTYPE html>
<html >
<head>
<meta charset="UTF-8">
<title>Javascript preloader</title>
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<div class="preloader"></div>
<canvas id='canvas'></canvas>
<script src="js/index.js"></script>
<img src="https://wallpaperscraft.com/image/stars_sky_shore_84534_1920x1080.jpg" alt="safe"></img>
</body>
</html>
**编辑道歉代码
<!DOCTYPE html>
<html >
<head>
<meta charset="UTF-8">
<title>Preloader Testing</title>
<style>
.preloader{
position: fixed;
top: 0;
left: 0;
width: 100vw;
height: 100vh;
z-index: 1000;
}
</style>
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<canvas class="preloader" id='canvas'></canvas>
<script src="js/index.js"></script>
<img src="https://wallpaperscraft.com/image/stars_sky_shore_84534_1920x1080.jpg" alt="safe"></img>
</body>
<script>
//after window is loaded completely
window.onload = function(){
//hide the preloader
document.querySelector(".preloader").style.display = "none";
}
</script>
</html>
最佳答案
您可以默认显示预加载器。一旦网页完全加载，您只需将其隐藏即可。这是一个代码示例
<!DOCTYPE html>
<html >
<head>
<meta charset="UTF-8">
<title>Javascript preloader</title>
<link rel="stylesheet" href="css/style.css">
<style>
/*Styling preloader*/
.preloader{
/*
Making the preloader floating over other elements.
The preloader is visible by default.
*/
position: fixed;
top: 0;
left: 0;
width: 100vw;
height: 100vh;
z-index: 1000;
}
</style>
</head>
<body>
<div class="preloader"><span class="preloader-js"></span></div>
<canvas id='canvas'></canvas>
<script src="js/index.js"></script>
<img src="https://wallpaperscraft.com/image/stars_sky_shore_84534_1920x1080.jpg" alt="safe"></img>
</body>
<script>
//after window is loaded completely
window.onload = function(){
//hide the preloader
document.querySelector(".preloader").style.display = "none";
}
</script>
</html>谢谢
