Question

我正在尝试为花朵SVG图像设置动画，使其看起来像花朵正在绘制，如this文章中所述。我已将当前代码包含在JSFiddle here中。

我似乎无法访问每个路径元素，我不太清楚为什么。我使用了文章中提供的Javascript代码，我下载/包含了我在网上找到的SVG花的svg HTML。当我运行代码时，Firefox，Safari和Chrome中的控制台会记录0，告诉我没有带有标记名称路径的元素。我不确定为什么会这样;任何人都可以解释为什么/我应该解决什么？

以下是javascript代码：

var paths = document.getElementsByTagName('path');
console.log(paths.length);
for (var i = 0; i < paths.length; i++) {
    var path = paths[i];
    var length = path.getTotalLength();
    // Clear any previous transition
    path.style.transition = path.style.WebkitTransition =
      'none';
    // Set up the starting positions
    path.style.strokeDasharray = length + ' ' + length;
    path.style.strokeDashoffset = length;
    // Trigger a layout so styles are calculated & the browser
    // picks up the starting position before animating
    path.getBoundingClientRect();
    // Define our transition
    path.style.transition = path.style.WebkitTransition =
      'stroke-dashoffset 2s ease-in-out';
    // Go!
    path.style.strokeDashoffset = '0';
}

以下是我的一些HTML代码：

Answer 1

解决了这个问题。因为我的Javascript代码是在我的HTML代码之前加载的，所以它注册了0个路径。我把脚本标签放在和之间，并且它起作用了。
