我有一个 CSS 下拉菜单似乎工作正常,除了一件事,即每次单击子菜单内的任何链接时折叠下拉菜单项。因此,当用户单击子菜单中的链接时,他们可以使用 JQuery 查看我在同一页面中的内容。
我已经看到有关如何折叠下拉菜单 onClick 的不同问题,但它们似乎对我的情况没有帮助。
这是我的示例 html 和 CSS,我希望有人可以帮助我纠正这个问题。最初我不得不努力将内容加载到
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link rel="stylesheet" type="text/css" href="css_dropdown.css" />

<title>CSS Dropdown menu with load content in DIV element</title>

</ul></li>
</ul>
<div class="container">
<!-- This is an empty container for loading linked content allowing to stay on the same page as the dropdown list -->
</div>
<!--This script needs to be loaded last for the browser to accept to make it work.-->
<script type="text/javascript">
$(".section").on("click", "a", function(e){
e.preventDefault();
$(".container").load( $(this).prop("href") );
// Stop regular handling of "click" in IE (and some others)
return false;
});
</script>
</body>
</html>
