将css：悬停效果更改为jquery.onclick（）

Question

I want to create a dropdown menu (for mobile: media queries are already working) but I want to change the :hover effect of my menu button (CSS) to jquery .onclick() function.

I know my code isn't far away of working but I am not beeing able to fix what's wrong.

Anyone could give me a tip?

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>

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

Instead of the pseudo selector .navigation:hover use a new class like .navigation.open in css, then use .toggleClass() to toggle the menu visibility in the click() handler

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');
    });
})

Note: In your fiddle, you forgot to add jQuery library
