DOM Exception: HIERARCHY_REQUEST_ERR (3) error
提问by PeterLin
The following code works fine in chrome and Firefox, but breaks in IE 9.0.
以下代码在 chrome 和 Firefox 中运行良好，但在 IE 9.0 中会中断。
message.nodeTree.childNodes[1].childNodes[0].childNodes[0].appendChild(pkf_util.createXmlTextNode(text));
message.nodeTree.childNodes[1].childNodes[0].childNodes[0].appendChild(pkf_util.createXmlTextNode(text));
when I try to input something via textarea,it comes with SCRIPT5022:
当我尝试通过 textarea 输入内容时，它带有 SCRIPT5022：
DOM Exception: HIERARCHY_REQUEST_ERR (3) line 481 character 29;
DOM 异常：HIERARCHY_REQUEST_ERR (3) line 481 character 29;
Any ideas why it's not working in IE 9.0?
任何想法为什么它不能在 IE 9.0 中工作？

I know its a long time since the Q was asked but I reached it based on the error message. specifically in my case I was getting the following error: "HIERARCHY_REQUEST_ERR: DOM Exception 3: A Node was inserted somewhere it doesn't belong.".
我知道自问 Q 以来已经很长时间了，但我根据错误消息到达了它。特别是在我的情况下，我收到以下错误：“HIERARCHY_REQUEST_ERR：DOM 异常 3：一个节点被插入到它不属于的地方。”。
I was trying to append a node that I was creating using jquery to some other node in my html document.
It turned out that by mistake I used $('div')instead of $('<div>')for the creating the new (appended) node.
我试图将我使用 jquery 创建的节点附加到我的 html 文档中的其他节点。事实证明，我错误地使用$('div')而不是$('<div>')用于创建新（附加）节点。
I hope this will help someone in the future.
我希望这会在将来对某人有所帮助。

This can be a solution...
这可以是一个解决方案......
var element = document.createElement('iframe');
element.src = url;
document.getElementsByTagName('body')[0].appendChild(element);
Good luck
祝你好运

DOM exception 3means you've tried to insert an element to a place in the DOM where it doesn't belong.
(ref.)
DOM exception 3意味着您已尝试将元素插入 DOM 中不属于它的位置。（参考）
Possible causes:
可能的原因：
- IE9 doesn't consider the XML node created by the library a valid DOM node.
- The node created is a valid DOM node but it's being appended somewhere it doesn't belong (such as anything being appended to a node that's supposed to be a leaf)
- The node created is not actually a new element, but rather a parent of the node being appended to. This would classify as a bug in the library.
- If you try to append a
nullanywhere, you're practically asking for a DOM exception. Perhaps your library fails on IE9?
- IE9 不认为库创建的 XML 节点是有效的 DOM 节点。
- 创建的节点是一个有效的 DOM 节点，但它被附加到它不属于的地方（例如任何被附加到应该是叶子的节点）
- 创建的节点实际上不是一个新元素，而是被附加到的节点的父节点。这将归类为库中的错误。
- 如果您尝试在
null任何地方附加 a ，您实际上是在请求 DOM 异常。也许你的图书馆在 IE9 上失败了？
Google search on pkf_utilreturns ... this question, so we cannot rule out a bug in pkf_util.
谷歌搜索pkf_util返回......这个问题，所以我们不能排除pkf_util.
