进度条没有动画或出现

Question

我是 Bootstrap 的新手。我下载了两个与简历相关的主题。一个主题有进度条，另一个主题。所以我从这里复制了代码并粘贴到另一个索引文件中。进度条出现，但它是空的并且没有动画。请帮助我，我被卡住了。我也复制并粘贴了 CSS 代码。 以下是我复制并粘贴到其他主题的代码：

动画（线的增长，至少在引导程序 3 中，是这样工作的：

$(function() {
  $('.progress-bar').each(function() { // loops through all bars
    var percent_fill = $(this).attr('aria-valuenow') + '%'; // grabs the % from your html aria-valuenow attribute.               
    $(this).animate({ width: percent_fill }, { duration: 2000 }); //animates. Here is where you could pass additional easing function if desired with the help of jquery ui
  });
});

现在我们缩小了 Bootstrap 3 的范围，您需要遍历进度条并为每个进度条分配值，而不是我硬编码的 80%。你需要 jQuery，如果上面的代码有效，你就有了。如果你想使用花哨的缓动/动画功能，你可能也需要 jQuery UI。但你现在不知道。

我已经修改了上面的截图来处理你的例子。
