svg里面的SVG动画:使用元素。适用于Firefox,而不适用于Chrome

我正在使用svg:use元素在一个包含许多节点的大型D3.js树中嵌入一个动画SVG微调器。

一个节点如下所示:

<g class="node clickable" data-path="1" data-depth="0" transform="">
  <text class="title" x="0" y=".36em" style="fill-opacity: 1;" text-anchor="begin">Model</text>
  <text class="subtitle" x="0" y="2em" style="fill-opacity: 1;" text-anchor="begin">
  <use href="static/spinner.svg#spinner" transform="translate(54.75,-9) rotate(0 7,9)">
</g>

我使用JQuery在需要时在树中的许多g.node元素之一中插入微调器。

微调器的SVG源如下:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

        <line x1="66.018" y1="94.007" x2="59.064" y2="74.901" opacity="0.2">

        <line x1="9.442" y1="73.417" x2="27.052" y2="63.25" opacity="0.2">
      <animate attributeType="CSS" attributeName="opacity" from="1" to="0.1" dur="1.2s" repeatCount="indefinite" begin="0.8s" />
    </line>    
    <line x1="3.879" y1="41.868" x2="23.904" y2="45.399" opacity="0.2">
      <animate attributeType="CSS" attributeName="opacity" from="1" to="0.1" dur="1.2s" repeatCount="indefinite" begin="0.9333s" />
    </line>    
    <line x1="19.897" y1="14.124" x2="32.966" y2="29.7" opacity="0.2">
      <animate attributeType="CSS" attributeName="opacity" from="1" to="0.1" dur="1.2s" repeatCount="indefinite" begin="1.0666s" />
    </line>
  </g>
</svg>

这适用于Firefox,但不适用于Chrome或Safari。在Chrome和Safari中,只显示动画的第一个“框架”,但是微调器不是动画。

有谁知道如何解决这个问题?

谢谢!

答案 0 :(得分:2)

显然,Chrome不会(自动)在嵌入式外部SVG文件中播放动画,但我发现当use元素引用的SVG未从外部文件加载而是从文档中的某个位置加载时

临时解决方案如下:
