我一直在制作这个模板页面，并希望它能够在按下菜单按钮后，在某个屏幕尺寸以下导航栏变得可扩展。我有媒体工作，但jquery不会使菜单滑出。我只是担心目前的功能，以后可以处理美学问题。此外，我使用JQuery，因为我觉得它更容易使用（可能不需要，但我更喜欢它，因为它节省了我的时间）。

您应该将z-index属性添加到菜单按钮。添加一些类，例如：
<button id = "menu" class="menu-btn">Menu</button>
之后添加以下css：
.menu-btn{
position:relative;
z-index: 1;
}
答案 1 :(得分：0)
原因是由于“欢迎”页面标题重叠（位置：绝对;），因此您的“菜单”按钮目前无法点击。首先，您需要将“菜单”按钮设置为顶层以使其可单击。 （make position：absolute; z-index：3）。您的JS功能没有任何问题。
更改您的CSS代码，如下所述。
#menu {
position: absolute;
z-index: 3;
}
@media only screen and (max-width: 940px) {
.head_small {
display: block;
}
}
答案 2 :(得分：0)
我对您的代码进行了一些更改，并创建了JSFiddle。
首先，您需要一个z-index因为“欢迎”覆盖了您的幻灯片按钮。
z-index属性仅在您的元素position属性absolute, fixed or relative animate检查this Page以获取更多信息时才有效：
第二件事是你使用JQuery到.nav_ul_small .slideToggle()，这只会在你第一次点击按钮时触发。所以你没有选择再次关闭菜单。
在这里，我使用了JQuerys .toggle()，您也可以使用<?php
if(isset($_POST['checkbox'])) {
// Set "activation_status" to 1.
} else {
// Set "activation_status" to 0.
}
。
我还制作了更简单的示例，我删除了大部分不必要的内容，以便您更容易理解。
