Question

我已经编码为使菜单按钮仅在xs模式下显示。它出现在每个屏幕尺寸上。而且它不会下降。如下所示，我得到错误代码。我只是一个初学者。我不能为此掩饰。我将不胜感激。

我的代码：

Failed to load resource: the server responded with a status of 404 (Not Found)
script.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)
jquery-1.11.3.min.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)

Answer 1

状态404（未找到）表示您传递了错误的资源URL，或者您没有在正确的位置放置资源，请尝试其他URL。菜单按钮中的错误可能是由于未加载资源引起的。

在最后一个错误中，您显然在传递JavaScript所需的HTML文件。

下拉按钮不起作用也不会消失
