【问题描述】：

我的页面上有一个svg 元素，并创建了一个定义来包含一个指定阴影效果的过滤器

效果在 Chrome 和 Firefox 上完美运行，但 IE11 无法呈现效果。

<svg class="historicUploadDonuts" width="254.375" height="254.375" filter="url(&quot;#ieDropShadow0&quot;)">
  <defs>
    <filter id="ieDropShadow0" height="130%">
      <feGaussianBlur in="SourceAlpha" stdDeviation="3" result="blur"></feGaussianBlur>
      <feOffset in="blur" result="offsetBlur" dx="3" dy="3"></feOffset>
      <feMerge>
        <feMergeNode></feMergeNode>
        <feMergeNode in="SourceGraphic"></feMergeNode>
      </feMerge>
    </filter>
  </defs>

  </g>
</svg>

我按照这里的示例 - http://xn--dahlstrm-t4a.net/svg/filters/arrow-with-dropshadow.svg - 但无法让效果在 IE11 上运行

有效的示例使用多边形 - 我使用的 svg 没有选择过滤器ieDropShadow0 有什么原因吗？

【解决方案1】：

在最外层的g.slices 元素上设置过滤器。去掉内引号。
