javascript - 我试图创建一个折叠侧边栏，但是一旦我在导航栏下方创建另一个部分，它就会不可见

问题描述

我现在面临的主要问题是当我尝试点击汉堡菜单时侧边栏消失了。我找不到代码有什么问题。

<body>

    <nav class="navbar">
    <div class="leftNav">

这是侧边栏


            <div class="sideBar" id="sideBar">

下面是切换按钮


                <div class="toggleBtn" onclick="togglesideBar(this)">
                    <div class="lines"></div>
                    <div class="lines"></div>
                    <div class="lines"></div>
                </div>
                <ul id="navList">
                    <li id="item-1"><a href=""> Home</a></li>

                    <li id="item-3"><a href="">Services</a></li>
                    <li id="item-4"><a href="">Blog</a></li>
                    <li id="item-5"><a href="">Contact</a></li>
                </ul>
            </div>
            <div class="logo">
                <img src="logo1.png" alt="">
            </div>
        </div>
        <div class="rightNav">
            <input type="text" name="searchBox" id="searchBox" placeholder="Enter your search">
            <button id="search">Search</button>
        </div>
    </nav>

当我创建这个部分时，侧边栏消失了，我无法点击侧边栏中的任何按钮


    <section class="firstSection">
        <div class="mainBox">
            <h1> <span id="typed"></span> </h1>
            <p>Lorem ipsum dolor, sit amet consectetur adipisicing elit. Totam est aut molestiae minima aliquid voluptates amet iste? Optio suscipit quod, dolor provident dolore unde impedit possimus, sit aut dolorem quos?</p>
            <div class="buttons">
                <button class="sec-Btn">Browse Blog</button>
                <button class="sec-Btn">Browse Services</button>
                <button class="sec-Btn">Contact</button>
            </div>
        </div>
    </section>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/typed.js/2.0.9/typed.min.js" async defer></script>
    <script src="index.js"></script>
</body>

</html>

<-----CSS CODE---->
* {
    margin: 0;
    padding: 0;
    font-family: 'Ubuntu', sans-serif;
}

我创建了一个汉堡菜单来折叠并打开一个侧边栏

/* creating a hamburger */

.lines {
    width: 20px;
    height: 3px;
    background-color: white;
    margin: 3px;
}

.toggleBtn {
    position: relative;
    left: 235px;
    top: 30px;
    cursor: pointer;
}

我设置到 SideBar 的所有属性


.sideBar {
    position: absolute;
    top: 0px;
    left: -200px;
    width: 200px;
    height: 100%;
    background: black;
    transition: all 300ms linear;
}

当我单击汉堡包打开侧边栏时，活动的类用于侧边栏我已经用 javascript 切换了它

#sideBar.active {
    left: 0px;
}

#navList li {
    list-style: none;
    padding: 10px 4px;
    border-bottom: 1px solid grey;
}

#navList li a {
    text-decoration: none;
    color: white;
    font-size: 17px;
}

#navList li a:hover {
    color: orange;
    transition: all 0.5s;
    /* border: 1px solid orange;
    padding: 2px 4px; */
}

.navbar {
    display: flex;
    align-items: center;
    background: black;
    /* border: 2px solid blue; */
}

.leftNav {
    width: 60%;
    /* border: 2px solid black; */
}

.rightNav {
    width: 40%;
    /* border: 2px solid black; */
}

.logo {
    /* border: 2px solid blueviolet; */
    width: 40%;
    display: flex;
    justify-content: center;
    margin: 5px 60%;
}

.logo img {
    width: 45%;
    margin-top: 5px;
}

.rightNav {
    text-align: right;
    padding: 0px 20px;
}

#searchBox {
    font-size: 20px;
    border-radius: 8px;
    border: 2px solid gray;
    padding: 4px 2px;
}

#search {
    font-size: 18px;
    border: 2px solid gray;
    border-radius: 8px;
    padding: 5px 5px;
    background: transparent;
    color: white;
}

#search:hover {
    box-shadow: 2px 2px 4px white;
}

该部分的代码在这里。这是我在创建导航栏和侧边栏后创建的唯一部分


/* Section-1 */

.firstSection {
    /* background: url('last.jpg')center center no-repeat; */
    /* background: white; */
    height: 80vh;
    display: flex;
}

.firstSection ::before {
    content: "";
    background: url('last.jpg')center center no-repeat;
    background-size: cover;
    opacity: 0.9;
    position: relative;
}

.mainBox {
    /* border: 2px solid black; */
    max-width: 70%;
    margin: auto;
}

.mainBox h1 {
    font-size: 30px;
    font-size: 34px;
    text-align: center;
    color: white;
}

.mainBox p {
    font-size: 19px;
    text-align: center;
    color: white;
}

.buttons {
    max-width: 49%;
    /* border: 2px solid yred; */
    /* border: 2px solid red; */
    margin: auto;
    margin-top: auto;
    margin-top: 10px;
}

.sec-Btn {
    padding: 10px 15px;
    border: 2px solid white;
    border-radius: 8px;
    font-size: 16px;
    color: white;
    background-color: transparent;
    font-weight: bold;
    margin: 0px 3px;
}

.sec-Btn:hover {
    box-shadow: 2px 2px 4px white;
    transition: all 0.5s;
}

<---JAVASCRIPT CODE--->

这是切换侧栏类的代码

function togglesideBar(ref) {
    document.getElementById('sideBar').classList.toggle('active');
}

此代码用于我的部分中的动画标题。我使用了一个 javascript Typed.js 库

window.onload = function() {
    console.log("loaded")
    var typed = new Typed('#typed', {
        strings: ["Welcome to Sanan.com", "Learn Web Development", "Learn App development", "Learn Facebook Ads", "and other awesome programming concepts with me :)"],
        backSpeed: 15,
        smartBackspace: true,
        backDelay: 1200,
        startDelay: 1000,
        typeSpeed: 25,
        loop: true,
    });
}
