带有javascript / jquery的菜单滑块

问题描述 投票:0回答:1

我正在尝试为一家餐厅制作菜单滑块,其中包含两个可点击的菜单,午餐菜单和晚餐菜单。我不希望菜单在新窗口中打开,只需一个干净的点击即可打开所需的菜单。

这是我到目前为止的代码,我知道它需要很多工作,我是javascript / jQuery世界的新手。纯javascript会很酷,但任何jQuery都可以工作。

如果有人可以帮助我,请解释需要修复的内容,以便我能够理解这一点,我会非常感激。谢谢You. On codepen

let lunchContainer = document.querySelectorAll('div.lunchmenu');
        dinnerContainer = document.querySelectorAll('div.dinnermenu');

function reset() {
    for(let i = 0; i < lunchContainer.length; i++) {
        lunchContainer[i].style.display = 'none'; 
        dinnerContainer[i].style.display = 'none'; 
    }
};

$('.lunch').click(function(event) {
    reset();
    $('.lunchmenu').addClass('active');
    lunchContainer.style.display = 'block';
});

$('.dinner').click(function() {
    reset();
    $('.lunchmenu').removeClass('active');
});

$('.dinner').click(function(event) {
    reset();
    $('.dinnermenu').addClass('active');
    // dinnerContainer.style.display = 'block';
});

$('.lunch').click(function() {
    reset();
    $('.dinnermenu').removeClass('active');
    // dinnerContainer.style.display = 'block';
});

注意我删除了多少代码!如果您要使用“活动”类来完成该工作,则无需设置显示,也无需定义按钮上两次单击的行为。

此外,如果每个菜单都有一个容器,则不需要遍历其中的所有项目以将其显示设置为none,将父容器设置为none就足够了。

希望有所帮助!

let lunchContainer = document.querySelectorAll('.lunchmenu'), // notice ',' instead of ';'
    dinnerContainer = document.querySelectorAll('.dinnermenu');
        
        
$('.lunch').click(function(event) {
    $('.dinnermenu').removeClass('active');
    $('.lunchmenu').addClass('active');
            
});
        
$('.dinner').click(function() {
    $('.lunchmenu').removeClass('active');
    $('.dinnermenu').addClass('active');
});
        

   
.lunchmenu, .dinnermenu {
  display:none;
}

.active {
  display:block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<button class="lunch">lunch</button>

<button class="dinner">dinner</button>

<div class="lunchmenu">
    <h5>lunch menu yayyy</h5>
    <p>item lunch 1</p>
    <p>item lunch 2</p>
</div>
<div class="dinnermenu">
    <h5>Dinner menu yayyy</h5>
    <p>itemdinner 1</p>
    <p>item dinner 2</p>
</div>
