最近需要写一个进度条的效果，网上找了一些，但都不能完美的实现需求。
于是就自己改造了一个，效果如下图：
因为动态图太大，我上传到 GitHub 了，就不在博客上再上传了。
百分比跟随进度条移动，百分比数字也随之变化。
进度条动画效果可选，颜色可根据自己的需求修改。
代码如下：
html：
JS：需要引jQuery
var a = 0,
timer = setInterval(function () {
a++ //10-11秒 a+=10=>1-2秒
$(".progress-value").html(a + "%");
$(".progress-bar").width(a + "%");
if (a == 80) {
clearInterval(timer);//清除定时器
$(".progress-bar").removeClass("active");
location.href = "#";//跳转链接
}
}, 100);
CSS：.progress {
height: 20px;
background-color: #f5f5f5;
-webkit-box-shadow: inset 0 1px 2px rgba(0, 0, 0, .1);
box-shadow: inset 0 1px 2px rgba(0, 0, 0, .1);
overflow: visible;
border-radius: 20px;
margin: 80px 20px;
}
.progress .progress-bar {

}
