防止在单击和关闭覆盖菜单 css 时滚动正文

Question

目前我有一个通过单击启动的覆盖 CSS 菜单。但是它后面的页面仍然是可滚动的。我确信这是一个简单的修复，但我是 css/js 的新手，任何帮助都会很棒！

目前我有一个 js 切换功能，当点击 .icon（汉堡图标）时，.mobilenav（覆盖菜单）会在页面上淡出。

启用此切换功能后，我可以添加哪种功能来防止正文滚动？

我可以在下面轻松添加到此功能吗？

    $(document).ready(function () {
    $(".icon, .link").click(function () {
        $(".mobilenav").fadeToggle(700);
        $(".top-menu").toggleClass("top-animate");
        $(".mid-menu").toggleClass("mid-animate");
        $(".bottom-menu").toggleClass("bottom-animate");
    });
});

Answer 1

我猜你正在寻找这样的东西：

document.body.style.overflow="hidden"

为了能够再次滚动，请使用

document.body.style.overflow="scroll"

例子：

document.body.onclick=function(){
  this.style.overflow="hidden"
}

Click anywhere to disable scrolling<hr>

此外，当您使用 jQuery 时，类似这样的方法也可以：

$('body').css('overflow', 'hidden'); // disables scrolling
$('body').css('overflow', 'scroll'); // enables scrolling

    $(document).ready(function () {

        $(".icon, .link").click(function (event) {
            event.preventDefault();
            $('body').toggleClass('overflow');
            $(".mobilenav").fadeToggle(700);
            $(".top-menu").toggleClass("top-animate");
            $(".mid-menu").toggleClass("mid-animate");
            $(".bottom-menu").toggleClass("bottom-animate");
        });
    });

   Add the below piece of code into css file

  .overflow
  {
     overflow:hidden;
  }
