推荐答案

MSDN：insertAdjacentHTML方法 [ ^ ]：文档中的备注部分说：

MSDN: insertAdjacentHTML method[^]: Remarks section in the document says:

You cannot insert text while the document is loading. Wait for the onload event to fire before attempting to call this method.

When using the insertAdjacentHTML method to insert script, you must include the DEFER attribute in the script element.

很可能你的文档没有完全加载。如果你正在使用jQuery，有一个非常方便的方法 document.ready（） [ ^ ]只会在您的文档后调用已经完全装满了。您可以将代码放在此方法中。如果您不确定，请在调用此代码之前确保您的文档已完全加载。



希望有所帮助！

Quite possibly your document has not completely loaded. If you are using jQuery there is a very handy method document.ready()[^] which will be called only after your document has completely loaded. You can put your code inside this method. If you are not sure, make sure your document has completely loaded before this code is called.

Hope that helps!
