Question

我遇到的问题似乎只会影响IE和Edge（在IE9-11＆amp; Edge 12-13上测试过）。我用Snap.svg制作一个SVG笔画偏移动画似乎运行正常，但在某些点上，笔画似乎超出界限＆＃34;并消失。它是奇怪的，因为viewBox设置为明显适合该行（它直接从Illustrator导出，带有适合整行的画板）。

您可以在此处查看此操作：http://codepen.io/ndimatteo/full/zqLBVW/

var bodyPathDinner = snake.select('#snake-body-dinner');

var headPath = snake.select('#snake-head');

// Draw Path
var bodyLength = bodyPath.getTotalLength();
var headLength = headPath.getTotalLength();

function snakeAnim() {

  //reset food

    snake.animate({ opacity: 1}, 200);

接下来的两次更改都有reach good result和IE11。

添加到SVG代码版本和样式：

<svg 
    viewBox="0 0 800 400"  
    version="1.1"
    style="
        shape-rendering:auto; 
        text-rendering:auto; 
        image-rendering:auto; 
        fill-rule:evenodd; 
        clip-rule:evenodd"
>

启用IE模拟边缘模式：

<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

但是通过将此字段添加到（codepen.io）/Settings/HTML/Stuff to <head>/头部没有变化，所以我通过F12/Document mode/Edge启用此模式（不要忘记按F5）。

我希望这会对你有所帮助。
