我一直试图创建一个与此示例不太相似的圆环图:https://jsfiddle.net/4azpfk3r/
HTML:
<div class="item html">
<h2>HTML</h2>
<svg width="160" height="160" xmlns="http://www.w3.org/2000/svg">
<g>
<title>Layer 1</title>
<circle id="circle" class="circle_animation" r="69.85699" cy="81" cx="81" stroke-width="8" stroke="#6fdb6f" fill="none"/>
</g>
</svg>
</div>
<div class="item css">
<h2>CSS</h2>
<svg width="160" height="160" xmlns="http://www.w3.org/2000/svg">

<title>Layer 1</title>
<circle id="circle" class="circle_animation" r="69.85699" cy="81" cx="81" stroke-width="8" stroke="#69aff4" fill="none"/>
</g>
</svg>
</div>
CSS
.item {
position: relative;
float: left;
}
.item h2 {
text-align:center;
position: absolute;
line-height: 125px;
width: 100%;
}
svg {
transform: rotate(-90deg);
}
.circle_animation {
stroke-dasharray: 440;
stroke-dashoffset: 440;
}
.html .circle_animation {
-webkit-animation: html 1s ease-out forwards;
animation: html 1s ease-out forwards;
}
.css .circle_animation {
-webkit-animation: css 1s ease-out forwards;
animation: css 1s ease-out forwards;
}
@-webkit-keyframes html {
to {
stroke-dashoffset: 80;
}
}
@keyframes html {
to {
stroke-dashoffset: 80;
}
}
@-webkit-keyframes css {
to {
stroke-dashoffset: 160;
}
}
@keyframes css {
to {
stroke-dashoffset: 160;
}
}
但是,在上面的例子和我的修改版本中,我都无法在IE 11和Edge中运行它们。我相当肯定这是由于中风 - dashoffset上的动画,但我不确定是否有任何解决方法。
注意:我已经尝试添加以下一行,因为一些类似的问题已经提出,但这并没有改变行为
<meta http-equiv="X-UA-Compatible" content="IE=edge">
答案 0 :(得分:0)
IE11不支持SVG元素的CSS动画。因此,如果要支持非Edge IE,则需要使用不同的方法。
然而,自构建10240以来,Edge一直支持SVG元素的CSS动画。
您的动画不在Edge上工作的原因是因为Edge坚持要求您包含具有CSS值的单位。其他浏览器对SVG值更宽容。
因此,要修复此问题,请将px
添加到所有的dasharray和dashoffset值。
.circle_animation {
stroke-dasharray: 440px;
stroke-dashoffset: 440px;
}
@keyframes html {
to {
stroke-dashoffset: 80px;
}

.item {
position: relative;
float: left;
}
.item h2 {
text-align:center;
position: absolute;
line-height: 125px;
width: 100%;
}
svg {
transform: rotate(-90deg);
}
.circle_animation {
stroke-dasharray: 440px;
stroke-dashoffset: 440px;
}
.html .circle_animation {
