一个网页进度条,运行于CSS将进度条美化为渐变色,同进使用JavaScript控制CSS对进度条背景进行适时平铺,演示程序仅演示了进度条的样式,应用到网页还需要继续修改。

<html>
<head>
<title>CSS+JS打造带渐变的进度条</title>
<style>
#load{width:500px;height:25px;border:1px #000 solid;}
#loading{position:absolute;z-index:2;height:23;filter:progid:DXImageTransform.microsoft.gradient(gradienttype=1,startColorStr=white,endColorStr=#39867b);}
#loadtext{position:absolute;z-index:3;width:100%;height:100%;line-height:23px;text-align:center;}
</style>
</head>
<body>
<div id="load"><div id="loading"></div><div id="loadtext">1%</div></div>
<script>
var i=0;
function test(){
	i++;
	document.getElementById("loading").style.width = i + "%";
	document.getElementById("loadtext").innerText = i + "%";
	if(i<100)setTimeout("test()",200);
}
setTimeout("test()",200);
</script>
</body>
</html>
