Question

我想创建一个下拉菜单（对于移动设备：媒体查询已经在运行）但我想将菜单按钮（CSS）的:hover效果更改为jquery .onclick()功能。

我知道我的代码离工作不远，但我无法修复错误。

任何人都可以给我一个提示？

HTML

<ul class="navigation">
     <img src="img/menu.png" alt="mobile" width="50" height="50" id="mobile"/>
     <li class="n1"><a href="#">Home</a></li>
     <li class="n2"><a href="#">Portfolio</a></li>
     <li class="n3"><a href="#">Services</a></li>
     <li class="n4"><a href="#">About</a></li>
     <li class="n5"><a href="#">Contacts</a></li>
</ul>

CSS

#mobile:hover{background-color: rgba(255, 255, 255, 0.15);}

a{text-decoration: none;color: white; padding: 10px 50px; font-weight: bold}

a:hover { color: #777; font-weight: bold;}

JQUERY / JS

$(".navigation").addClass("js");
$(".navigation").addClass("js").before('<img src="img/menu.png" alt="mobile" width="50" height="50" id="mobile"/>');

$("#mobile").click(function(){
    $(".navigation").toggle();
});

Answer 1

而不是伪选择器.navigation:hover在css中使用.navigation.open之类的新类，然后使用.toggleClass()切换click()处理程序中的菜单可见性

jQuery(function ($) {
    //$(".navigation").addClass("js");
    //$(".navigation").addClass("js").before('<img src="img/menu.png" alt="mobile" width="50" height="50" id="mobile"/>');

    $("#mobile").click(function () {
        $(".navigation").toggleClass('open');
    });
})

注意：在你的小提琴中，你忘了添加jQuery库
