未捕获的错误：NOT_FOUND_ERR：用于appendChild调用的DOM异常8

问题描述

错误发生在最后此代码段的行：

The error occurs on the last line of this snippet:

 var anchor = "<a id=\"hostname\" href=\"" + destination + "\"> "+ imagename + "</a>";
 var specialdiv = document.getElementById("specialdiv");
 console.log("div: " + specialdiv);
 specialdiv.appendChild(anchor);

真的没有其他事情......我验证了 specialdiv 不是null或类似的东西。任何人都可以解释为什么我在该行上收到此错误？

There's really nothing else going on... I verified that specialdiv isn't null or something like that. Can anyone explain why I'm getting this error on that line?

推荐答案

不传递字符串，而是传递元素

don't pass a string, but an element

var link = document.createElement('a');
link.innerHTML = imagename;
link.id = "hostname";
link.href = destination;

var specialdiv = document.getElementById("specialdiv");
specialdiv.appendChild(link);
