list_node.innerHtml('');
innerHTML is a property, not a function; innerHTML是属性，而不是函数； and innerHtml doesn't exist, unless something you're using is defining it. 并且innerHtml不存在，除非您正在使用的东西对其进行定义。 Most browsers' javascript console would have alerted you to this. 大多数浏览器的JavaScript控制台都会提醒您这一点。
Normally, script execution stops when an uncaught exception occurs. 通常，当发生未捕获的异常时，脚本执行会停止。 So the script stopped there. 因此脚本停止在那里。

“ innerHTML”不是功能。
list_node.innerHTML = '';

As discussed by other's, you need to change the line where you set the inner HTML to 正如其他人所讨论的，您需要更改将内部HTML设置为的行。
`list_node.innerHTML = '';`
Noting that it is an attribute, not a function, and that case matters. 注意它是一个属性，而不是一个函数，这种情况很重要。
Also, you may want to add the following to your CSS to get all of the images to fill the height of the carousel automatically. 另外，您可能希望将以下内容添加到CSS中，以获取所有图像以自动填充轮播的高度。
#carousel img { height: 100%; }
