如何制作动画多色进度条？

Question

如果我问的不是很清楚，我很抱歉。我正在尝试构建一个在页面加载时动画的多色进度条。我找到了与我正在寻找的示例类似的示例，但是 javascript/jquery 给我带来了问题。我不擅长那个领域。

示例 1：https://codepen.io/tamak/pen/hzEer

该链接显示了我希望栏如何在页面出现时逐渐扩展并以特定百分比停止。

jQuery(document).ready(function(){
  jQuery('.skillbar').each(function(){
    jQuery(this).find('.skillbar-bar').animate({
      width:jQuery(this).attr('data-percent')
    },6000);
  });
});

示例 2：http://www.cssflow.com/snippets/animated-progress-bar/demo

非常接近我所追求的，但我希望进度条在没有按钮的情况下运行。颜色本身，从红色到绿色，是我想要实现的目标。

提前致谢！我知道这可能要求很多，但我希望有人愿意尝试一下。

Answer 1

也许这会有所帮助：Bootstrap progress bar with gradient color showing proportionally on active width

至于移动进度条，你到底想让它怎么改变？您不需要按钮来执行此操作，但需要发生一些事情。你能更详细地解释一下那篇文章吗？

您可以根据百分比设置具有时间间隔的按钮的点击事件。

$(document).ready(function(){
	var CurrentProgress =  '75%';
	setTimeout(function(){
  	$(".label").each(function() {
    	if($(this).html()==CurrentProgress){
      	$(this).click();
      }
    })
  },1000)
})

.container {
  margin: 80px auto;
  width: 640px;
  text-align: center;
}
.container .progress {
  margin: 0 auto;
  width: 400px;
}

.progress {
  padding: 4px;
  background: rgba(0, 0, 0, 0.25);
  border-radius: 6px;
  -webkit-box-shadow: inset 0 1px 2px rgba(0, 0, 0, 0.25), 0 1px rgba(255, 255, 255, 0.08);
  box-shadow: inset 0 1px 2px rgba(0, 0, 0, 0.25), 0 1px rgba(255, 255, 255, 0.08);

}
.progress-bar:before, .progress-bar:after {

  background-image: -o-linear-gradient(top, rgba(255, 255, 255, 0.3), rgba(255, 255, 255, 0.05));
  background-image: linear-gradient(to bottom, rgba(255, 255, 255, 0.3), rgba(255, 255, 255, 0.05));
