Question

我正在制作一个画布外推送菜单，一切正常，有些方面我似乎无法弄明白。

如何禁用滚动内容包装器。
如何仅滚动画布菜单。现在它滚动网站本身的高度。

这是一个代码笔，向您展示我遇到的问题。

HTML

    <div id="menu">
    <h1>This is the push over menu</h1>
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Accusamus alias id accusantium, consequatur, repellendus iure impedit consectetur aspernatur quas quo. Doloremque, facere autem ex tempora dicta consequuntur, possimus minima natus.</p>

  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Sint quis voluptatibus, nesciunt debitis ea ullam consectetur illo cum odit nobis explicabo cumque, vitae quia dolores, fugit maxime ad nisi earum.</p>

  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Repellendus voluptatibus dignissimos possimus, voluptatem ducimus illum voluptate deleniti et culpa autem laboriosam, pariatur voluptates enim facilis, animi nesciunt dolor expedita repellat.</p>
</div>

<div id="burger-icon">
    <h2>burger menu</h2>
</div>

<div id="content-wrapper">
  <h1>Main Content</h1>
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Voluptatum ullam, alias dignissimos dolore, a ratione dicta ipsam delectus facilis quod voluptates autem beatae sed impedit eligendi, consequuntur necessitatibus modi nemo?</p>
</div>

CSS

    #menu{
  position: absolute;
  left: -100%;
  background-color:red;
  width: 100%;
  min-height: 100%;
  z-index: 1000;
  padding-top: 50px;
}

#burger-icon {
  position:fixed;
  top: 10px;
  left: 10px;
  color: yellow;
  cursor: pointer;
  z-index: 2000;
}

#content-wrapper {
  padding-top: 40px;
  background-color: #000;
  color: #fff;
  min-height: 200vh;
}

JS

    var isOpen = false;

// sets the about off screen number
var aboutOffPosition = $("#menu").css("left");

//console.log($("#about").css("left"));

function openMenu() {
    // console.log("burger clicked");

    if(isOpen === false)
    {

        // slide over the about section
        TweenMax.to($("#menu"),".75", {left:0, ease: Power1.easeIn});

        // move over the content
        TweenMax.to($("#content-wrapper"),1, {x:500, ease: Power1.easeIn});

        isOpen = true;
    }
    else{

        // slide back the about section
        TweenMax.to($("#menu"),".75", {left:aboutOffPosition, ease: Power1.easeIn});

        // move back the content
        TweenMax.to($("#content-wrapper"),".5", {x:0, ease: Power1.easeIn});

        isOpen = false;
    }
}

// burger icon
$('#burger-icon').click(openMenu);

谢谢！

据我所知，你想要在菜单打开时禁用内容包装器的滚动，同时应该为菜单启用滚动。

你只需要从＃content-wrapper中删除min-height并将overflow设置为hidden来隐藏滚动。

#content-wrapper {
 padding-top: 40px;
 background-color: #000;
 color: #fff;
 overflow:hidden;
}
#menu{
  position: absolute;
  left: -100%;
  background-color:red;
  width: 100%;
  height: auto;
  z-index: 1000;
  padding-top: 50px;
}

我能够通过在内容周围添加容器（.app）并将此css应用于项目来解决此问题。

List<String> comboxTable = new List<string>();  
comboxTable = comboxTable.Where(m => !string.IsNullOrEmpty(m)).ToList();

我更新了codepen以反映这些更改。
