据我所知，没有真正的理由认为这段代码不起作用。我有一个 HTML 文件和一个外部 .js 文件。这是我在 html 内部使用的语句来加载 .js 文件:
<script type="text/javascript" src="family.js"></script>
文件名正确，且在同一目录下。我将在下面发布 html 页面的完整代码，以防出现其他问题。
有什么我想念的吗？ .js 文件应该制作一个滑动菜单，但它根本没有加载。我在 .js 文件中插入了一个警报，它应该在它工作时提醒我，尽管它没有显示。

最佳答案
问题不在于 MIME 类型，而在于 JS 脚本(如果它位于 'http://orca.st.usm.edu/~tbonnet2/440/p5/family.js')
缺少右括号，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);
}
