html - 我的 svg 在动画的某个时刻停止

Question

我有一个 SVG 元素(见下文)动画但一段时间后它停止动画。我希望动画继续像这样 jsfiddle .

.path {
    stroke-dasharray: 20;
    animation: dash 10s linear;
}

@keyframes dash {
    to {
        stroke-dashoffset: 1000;
    }
}

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="340px"
     height="333px" viewBox="0 0 340 333" enable-background="new 0 0 340 333"
     xml:space="preserve">
    <path class="path" fill="#fff" stroke="#000" stroke-width="2"
          d="m121.3,34.6c-1.6-1.6-4.2-1.6-5.8,0l-51,51.1-51.1-51.1c-1.6-1.6-4.2-

您只缺少 infinite 关键字。引用the docs了解更多。

.path {
    stroke-dasharray: 20;
    animation: dash 10s linear infinite;
}

@keyframes dash {
    to {
        stroke-dashoffset: 1000;
    }
}
