uncaught error NOT_FOUND_ERR DOM Exception 8
提问by
So I am deleting all the contents under a particular div and adding a message content. However, javascript throw the following error after the finish:
所以我删除了特定 div 下的所有内容并添加了消息内容。但是，javascript 在完成后抛出以下错误：
Uncaught Error: NOT_FOUND_ERR: DOM Exception 8
Here is the code where it is executed
这是它执行的代码
new Ajax.Request("profileThis.php",
{
method:'post',
parameters:{title:title, review:review, userId:userId, category:category, categoryId:categoryId},
onSuccess:function(ajax)
{
alert(ajax.responseText); // this is just for debugging purposes
var message=ajax.responseText;
var divMessage=document.createElement("div");
divMessage.style.color="rgb:(105,105,105)";
divMessage.innerHTML=message;
while($("reviewSheet").hasChildNodes)
{
$("reviewSheet").removeChild($("reviewSheet").lastChild);
}
$("reviewSheet").adopt(divMessage);
},
onFailure:ajaxFailure,
onException:ajaxFailure
});
People commented that the problem was with how I assigned divMessageto reviewSheet. I tried both adoptand appendChildbut none works.
A little help would be appreciated.
人们评论说，问题在于我如何分配divMessage给reviewSheet. 我两个都试过了adopt，appendChild但都没有效果。一点帮助将不胜感激。

Is the problem that you are calling the method hasChildNodes() on a jQuery object? I'm not sure what $("reviewSheet") is supposed to be, but wrapping a string in $() makes it a jQuery object which I don't believe will work with regular javascript methods. If "reviewSheet" is the id of an element you could do something like
问题是您在 jQuery 对象上调用方法 hasChildNodes() 吗？我不确定 $("reviewSheet") 应该是什么，但是在 $() 中包装一个字符串使它成为一个 jQuery 对象，我认为它不能与常规的 javascript 方法一起使用。如果“reviewSheet”是元素的 id，您可以执行以下操作
node = document.getElementById('reviewSheet');
then you could go into your while loop.
然后你可以进入你的while循环。
while (node.hasChildNodes()) {
//the rest of your code here
}
Oh also you need to put the parenthesis after hasChildNodes() to return a boolean value.
哦，您还需要将括号放在 hasChildNodes() 之后以返回布尔值。
