据我所知，没有真正的理由说这段代码不起作用。我有一个HTML文件和一个外部.js文件。这是我在html中使用的语句来加载.js文件：
<script type="text/javascript" src="family.js"></script>
文件的名称是正确的，它位于同一目录中。我将在下面发布html页面的完整代码，以防万一有其他内容。
我有什么遗失的吗？ .js文件应该是一个滑动菜单，但它根本就没有加载。我在.js文件中插入了一个警告，该警告应该在它工作时提醒我，尽管它没有出现。

问题不是MIME类型，而是在JS脚本中（如果它是'http://orca.st.usm.edu/~tbonnet2/440/p5/family.js'中的那个）
缺少右括号，请查看closeMenu（）：
function closeMenu() {
/* get the current menu id */
var ID = this.id + "List"
/* determine active menu */
activeMenu = document.getElementById(ID);
if (activeMenu) { // <------ THIS CONDITIONAL BLOCK ISN'T CLOSED!
activeMenu.style.display = "none";
activeMenu = null;
/* run the moveItemLeft function by setting a time interval */
timeID = setInterval("moveItemLeft()", 1);
}

例如，如果有关于加载该js文件的错误（并发布），请检查Firefox的控制台。 也许，文件已加载，但它包含的错误无法让您看到警报

我遇到的问题与问题的作者描述相同。
但是，在我的情况下，没有从磁盘重新读取js文件。 最初，当我开始测试HTML结构时，我的js文件是空的。 后来当我向js文件添加代码时，即使在“刷新”浏览器之后，已经打开的浏览器窗口也没有重新读取js文件。
js文件在那里，它位于同一目录中，但文件的内容是在浏览器中缓存的内存。我在Google调试器的某处看到了一条消息，但我无法再次找到该消息。消息说明HTML文件是磁盘缓存的，而js文件是内存缓存的。
当我点击浏览器的刷新按钮时，HTML文件被刷新，但是js文件没有刷新，并且在添加js内容之前从页面的初始运行开始在“sources”选项卡中显示为空。
要修复，我关闭浏览器窗口，打开一个新的浏览器窗口，一切都开始正常工作。新窗口从磁盘重新读取js脚本。

如果您没有上述答案中的任何错误，并且正在使用网络托管服务...。 1.登录到控制面板，然后检查文件是否确实存在。
我遇到了同样的问题，当我进行更改甚至更改了文件名时，我都使用ftp（winSCP）上传文件，我遇到了同样的问题，但是当我进入控制面板（文件管理器）时，我通过winSCP所做的更改没有得到体现，然后我通过控制面板上传了所有内容，一切开始正常运行。
