jQuery click事件在切换侧栏时仅工作一次

Question

I am trying to toggle a sidebar, but it works only once. I think the query code is self explanatory. Though I can write the HTML code if you want.

    $('.side-menu').on('click', function(){
        $('.control-sidebar').addClass('active-sidebar');
        $('.side-menu').on('click', function(){
            $('.control-sidebar').removeClass('active-sidebar');
        });
    });

Answer 1

A clean code solution would look somehow like this:

$('.side-menu').on('click', function(){
    $('.control-sidebar').toggleClass('active-sidebar');
});

Answer 2

I think the logic is not right in your case.

if(!$('.control-sidebar').hasClass('active-sidebar')){...}

This code will run when class "control-sidebar" don't have class "active-sidebar".

at the beginning, the case happens so you can click on .side-menu and add class "active-sidebar" to DOM. this against your first logic.

Moreover, why this happens twice in your code?

$('.side-menu').on('click', function(){...}

Solution: Use toggle class: see this https://jsfiddle.net/BeklievParviz/rwnpk0wm/

Answer 3

$('.side-menu').on('click', function(){
    $('.control-sidebar').toggleClass('active-sidebar');
});
