在移动设备中， 当用户触摸 (.menu-btn( 时，将显示 (.menu(，并且 (body( 被锁定以滚动。
但问题是(.menu(也被看了。
即使(正文(看起来滚动，我怎样才能使(.menu(可以滚动？

我知道有身体滚动锁定。 ： https://github.com/willmcpo/body-scroll-lock
不幸的是，我不允许将 webpack 用于此:(
<body>
<header>
<h2> Top area </h2>
<div class="menu-btn">
</div>
<div class="menu">
<h2> Hamburger menu area </h2>
</div>
</header>
<section class="contents">
<h2> Contents area </h2>
</section>
</body>
$('.menu-btn').on('click', function() {
$('.menu').toggleClass('active');
$('body').toggleClass('lock-scroll');
$('html').toggleClass('lock-scroll');
})
body {
width: 100%;
background-color: lavender;
}
body.lock-scroll {
overflow: hidden;
}
html.lock-scroll {
overflow: hidden;
}
header {
width: 100%;
height: 3em;
position: fixed;
top: 0;
background-color: beige;
z-index: 100;
}
.menu-btn {
width: 1em;
height: 1em;
background-color: lightseagreen;
position: fixed;
z-index: 300;
top: 1em;
right: 1em;
}
.menu {
width: 100%;
height: 130vh;
position: fixed;
top: 0;
z-index: 200;
padding-top: 40%;
background-color: rgba(255,255,255, .5);
transform: translateX(100%);
transition: all .5s ease;
}
.menu.active {
transform: translateX(0%);
}
.contents {
width: 100%;
padding-top: 50%;
height: 150vh;
background-color: lightblue;
}
h2 {
text-align: center;
}
添加一个.menu-content元素并将.menu元素的内容放在其中。
并将此样式添加到样式的末尾
.menu {
height: 100%;
overflow: scroll;
}
.menu-content {
height: 130vh;
}
