CSS

  overflow-y: hidden
}

Javascript
``let body = document.querySelector('body');
if(condition)  {
 //disable scroll on the entire body
 body?.classList.add("disable-scroll");
} 
else {
 //to remove the class attrib
 body?.removeAttribute("class");
 //or to remove the disable-scroll class only
 body?.classList.remove("dissble-scroll");
}

这比长代码好多了。容易理解

这个答案提出了一个解决方案，用于删除overflow: hidden时发生的“bump”。由于编辑被拒绝，下面是:

要删除overflow: hidden应用时发生的“凹凸”，您可以计算滚动条的宽度并用margin代替它。下面是body元素的例子:

const bodyScrollControls = {
  scrollBarWidth: window.innerWidth - document.body.clientWidth,

  disable() {
    document.body.style.marginRight = `${this.scrollBarWidth}px`;
    document.body.style.overflowY = 'hidden';
  },
  enable() {
    document.body.style.marginRight = null;
    document.body.style.overflowY = null;
  },
};

如果元素已经有右边距，那么获取现有的右边距并为其添加滚动条宽度应该不是问题。

根据你想要使用移除的滚动来实现什么，你可以只修复你想要移除滚动的元素(单击，或任何其他你想要临时禁用滚动的触发器)

我正在寻找一个“临时无滚动”的解决方案，这解决了我的需要

创建一个班级

.fixed{
    position: fixed;
}

然后用Jquery

var someTrigger = $('#trigger'); //a trigger button
var contentContainer = $('#content'); //element I want to temporarily remove scroll from

contentContainer.addClass('notfixed'); //make sure that the element has the "notfixed" class

//Something to trigger the fixed positioning. In this case we chose a button.
someTrigger.on('click', function(){

    if(contentContainer.hasClass('notfixed')){
        contentContainer.removeClass('notfixed').addClass('fixed');

    }else if(contentContainer.hasClass('fixed')){
        contentContainer.removeClass('fixed').addClass('notfixed');
    };
});

我发现这是一个非常简单的解决方案，适用于所有浏览器，也适用于便携式设备(如iphone，平板电脑等)。由于元素是临时固定的，所以没有滚动:)

注意!根据contentContainer元素的位置，你可能需要从左边调整它。这可以很容易地通过添加一个css左值的元素时，固定类是活跃的

contentContainer.css({
    'left': $(window).width() - contentContainer.width()/2 //This would result in a value that is the windows entire width minus the element we want to "center" divided by two (since it's only pushed from one side)
});

我知道这是一个老问题，但我不得不做一些非常相似的事情，在花了一段时间寻找答案并尝试了不同的方法后，我最终使用了一个非常简单的解决方案。

我的问题非常相似，几乎相同，唯一的区别是我不需要实际显示滚动条-我只需要确保它的宽度仍然被使用，所以当我的覆盖显示时，页面的宽度不会改变。

当我开始滑动覆盖到屏幕，我做:

$('body').addClass('stop-scrolling').css('margin-right', 8);

在我将覆盖层从屏幕上滑动后，我这样做:

$('body').removeClass('stop-scrolling').css('margin-right', 0);

重要:这是完美的工作，因为我的叠加是绝对定位，对:0px时可见。

这里有一个非常基本的方法:

window.onscroll = function () { window.scrollTo(0, 0); };

在IE6中有点不稳定。

我刚刚整理的一些东西:

斯菲德尔

document.onwheel = function(e) { // get the target element target = e.target; // the target element might be the children of the scrollable element // e.g., "li"s inside an "ul", "p"s inside a "div" etc. // we need to get the parent element and check if it is scrollable // if the parent isn't scrollable, we move up to the next parent while (target.scrollHeight <= target.clientHeight) { // while looping parents, we'll eventually reach document.body // since body doesn't have a parent, we need to exit the while loop if (target == document.body) { break; } target = target.parentElement; } // we want this behaviour on elements other than the body if (target != document.body) { // if the scrollbar is at the top and yet if it still tries to scroll up // we prevent the scrolling if (target.scrollTop <= 0 && e.deltaY < 0) { e.preventDefault(); } // similarly, if the scrollbar is at the bottom and it still tries to scroll down // we prevent it else if (target.clientHeight + target.scrollTop >= target.scrollHeight && e.deltaY > 0) { e.preventDefault(); } } }; body { background: gainsboro; } #box { width: 300px; height: 600px; padding: 5px; border: 1px solid silver; margin: 50px auto; background: white; overflow: auto; } <div id="box"> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
