我想显示多个循环进度条，但我无法在同一页面上显示多个循环进度条。
您可以在codepen示例中看到，我尝试添加多个div标签以显示多个进度条，但只显示一个。
我猜我可能需要为不同的div标签设置不同的值？任何帮助表示赞赏。
以下是codepen：http://codepen.io/Goatsy/pen/ZYbzyX

每个div都需要自己的ID。事实上，每个ID都必须是唯一的，才能使页面正常运行。 #progress选择器最多只能获取一个元素。
在这种情况下，无论如何我都会使用一个类而不是一个ID：
<div class="progress" data-dimension="150" data-color="#eee" data-text="HTML / HTML5" data-fontsize="14" data-percent="95" data-fgcolor="#d35225" data-bgcolor="#eee" data-width="15" data-bordersize="5" data-animationstep="2"></div>
<br/>
<div class="progress" data-dimension="150" data-color="#eee" data-text="HTML / HTML5" data-fontsize="14" data-percent="85" data-fgcolor="#d35225" data-bgcolor="#eee" data-width="15" data-bordersize="5" data-animationstep="2"></div>
<br/>
并初始化：
$(function() {
$('.progress').circliful();
});

您不能在一个页面上拥有多个ID。
但你可以有多个班级。
<强> JS：
改
$('#progress')至$('.progress')
<强> HTML：
将id="progress"更改为class="progress"
