Uncaught Error: NOT_FOUND_ERR: DOM Exception 8 for appendChild call
提问by user5243421

javascript appendChild doesn't work
The error occurs on the last line of this snippet:
错误发生在此代码段的最后一行：
var anchor = "<a id=\"hostname\" href=\"" + destination + "\"> "+ imagename + "</a>";
var specialdiv = document.getElementById("specialdiv");
console.log("div: " + specialdiv);
specialdiv.appendChild(anchor);
There's really nothing else going on... I verified that specialdivisn't null or something like that. Can anyone explain why I'm getting this error on that line?
真的没有其他事情发生......我确认它specialdiv不是空的或类似的东西。谁能解释为什么我在那条线上收到这个错误？

don't pass a string, but an element
不要传递字符串，而是传递元素
var link = document.createElement('a');
link.innerHTML = imagename;
link.id = "hostname";
link.href = destination;
var specialdiv = document.getElementById("specialdiv");
specialdiv.appendChild(link);

You are getting that error because appendChildtakes DOM elements, not strings. You need to actually create a DOM element before using appendChild.
您收到该错误是因为appendChild需要 DOM 元素，而不是字符串。在使用之前，您需要实际创建一个 DOM 元素appendChild。
var anchor = document.createElement('a');
anchor.id = "hostname";
anchor.href = destination;
anchor.innerHTML = imagename;
var specialdiv = document.getElementById("specialdiv");
specialdiv.appendChild(anchor);
