我试图将下面的代码转换为可扩展的版本,我尝试过使用vw和vh,%值等等,我似乎无法获得正确的价值平衡哪个工作。任何帮助表示赞赏。
此codepen也可能有所帮助:http://codepen.io/anon/pen/dPNgvP

您可以使用svg
和JavaScript来简化代码并使其动态化。
此代码的作用是什么?
text
标记中提取百分比值,计算角度并将其存储为动画。theta = 0
设置为计算出的角度。使用这种方法可以做的事情:
44%
代码中的text
即可动态设置百分比。
-%
| --%
| ---%
,包括浮动值。t
变量来更改动画速度。 CodePen上的响应式演示 ---&gt; width
的{{1}}和height
取决于svg
&#39; #container
。
width
&#13;
var dark = document.getElementById('dark'),
t = 5,
percentage = parseInt(document.getElementById('perc').innerHTML.slice(0, -1), 10),
theta = 0,
maxTheta = (180 * percentage) / 50,
radius = document.getElementById('svg').getBBox().width / 2;
dark.setAttribute('transform', 'translate(' + radius + ',' + radius + ')');
var animate = setInterval(function() {
theta += 0.5;
var d = 'M0,0 v' + -radius + 'A' + radius + ',' + radius + ' 1 ' + ((theta > 180) ? 1 : 0) + ',1 ' + Math.sin(theta * Math.PI / 180) * radius + ',' + Math.cos(theta * Math.PI / 180) * -radius + 'z';
dark.setAttribute('d', d);
if (theta > maxTheta) {
clearInterval(animate);
}
}, t);
&#13;
要设置多个百分比响铃,您可以使用<svg id="svg" width="140" height="140" viewBox="0 0 141 141">
<path id="light" d="M70,70 v-70 a70,70 0 0,1 0,140 a70,70 0 1,1 0,-140" fill="#DD1111" />
<path id="dark" d="M70,70 v-70 a70,70 0 0,1 0,0" fill="#710000" />
<path d="M20,70 a50,50 0 0,1 100,0 a50,50 0 0,1 -100,0" fill="white" />
<text id="perc" x="70" y="79" font-size="30px" text-anchor="middle">44%</text>
</svg>
es代替class
s。同样,您无需对JavaScript代码进行任何更改,只需更改id
代码中的百分比即可。

这是一个很好的插件pieProgress.js来执行此操作。这是demo和tutorial how to use this.
希望这能解决您的问题。
