我的页面顶部有一个进度条，我希望该条显示网页加载的进度。当整个页面加载时，我希望栏显示 100%。我很确定我需要列出一个变量 '$(window).load();' 但我不确定在哪里。
我的代码：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>test</title>
<style>
progress {
width: 100%;
height: 5px;
top: 0;
left: 0;
position: absolute;
color: #1990c8;
appearance: none;
-webkit-appearance: none;
-o-appearance: none;
}
progress::-moz-progress-bar {
background: #1990c8;
}
progress::-webkit-progress-value {
background: #1990c8;
}
progress::-webkit-progress-bar {
background: #e1e1e1;
}
</style>
</head>
<body>
<progress id="progressbar" value="0" max="100"></progress>
<span id="status"></span>
<script type="text/javascript" language="javascript">
function progressbaranimation(a) {
var bar = document.getElementById('progressbar');
bar.value = a;
a++;
var sim = setTimeout("progressbaranimation("+a+")");
}
var amount = 0;
progressbaranimation(amount);
</script>
