无法选择 SVG 图片中的路径

Not able to select paths in SVG picture

本文关键字：路径 选择 SVG      更新时间：2023-09-26

我正在尝试对花朵SVG图像进行动画处理，使其看起来像花朵正在绘制自己，如本文所述。我已经在这里将我当前的代码包含在JSFiddle中。

我似乎无法访问每个路径元素，我也不太确定为什么。我使用了文章中提供的Javascript代码，并下载/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 中的控制台记录 0，告诉我没有带有标签名称路径的元素。我不确定这是为什么;谁能解释为什么/我应该修复什么？

这是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';
}

这是我的一些HTML代码：

解决了

这个问题。因为我的 Javascript 代码在我的 HTML 代码之前加载，所以它注册了 0 个路径。我将脚本标签放在 和 之间，它起作用了。
