即使我等待SVG加载，也找不到对象#document元素
即使我等待SVG加载，也找不到对象#document元素

我有一个SVG，我正在尝试点击eventListener，它向下滚动并更改SVG的数据(就像动画)。问题是SVG的.contentDocument返回null，而我不能将它绑定到单击。我不太明白为什么，因为我在等待SVG加载，所以在我看来，它应该是工作的。下面是代码：
document.addEventListener("DOMContentLoaded", function(event) {
var video = document.querySelector("video");
var mySVG = document.querySelector("object");
var svgDoc;
mySVG.addEventListener("load",function() {
svgDoc = mySVG.contentDocument;
svgDoc.addEventListener("click", function() {
mySVG.setAttribute("data", "svg/Robot 2.svg");
video.scrollIntoView({behavior: "smooth"});
});
}, false);

您是否在Chrome上使用file:// URL进行本地测试？如果是的话，试试Firefox吧。Chrome将file:// URL视为不同的域，不允许您通过contentDocument属性访问它们的内容。
在Firefox中，下面的示例对我来说很好。为了清晰起见，我重新命名了你的一些变量。
<!DOCTYPE html>
<html>
<head>
<title>SVG + Object test</title>
<meta charset="UTF-8" />
</head>
<body>
<object
data="kiwi.svg"
type="image/svg+xml"
class="index-modificat"
></object>
<script>
var objectElem = document.querySelector("object");
objectElem.addEventListener("load", function () {
contentDoc = objectElem.contentDocument;
svg = contentDoc.documentElement;
console.log("svg = ",svg);
});
</script>
