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

根据galambalazs的帖子，我将添加对触摸设备的支持，允许我们触摸但不能上下滚动:

function disable_scroll() {
   ...
   document.ontouchmove = function(e){ 
        e.preventDefault(); 
   }
}

function enable_scroll() {
   ...
   document.ontouchmove = function(e){ 
     return true; 
   }
}

我很抱歉回答一个旧帖子，但我正在寻找一个解决方案，遇到了这个问题。

对于这个问题，仍然有许多变通办法来显示滚动条，比如给容器一个100%的高度和一个overflow-y: scroll样式。

在我的情况下，我刚刚创建了一个div与滚动条，我显示，同时添加overflow:隐藏到主体:

function disableScroll() {
    document.getElementById('scrollbar').style.display = 'block';
    document.body.style.overflow = 'hidden';
}

元素滚动条必须具有以下样式:

overflow-y: scroll; top: 0; right: 0; display: none; height: 100%; position: fixed;

这显示了一个灰色的滚动条，希望它有助于未来的访问者。

在Chrome 56和其他现代浏览器中，你必须在addEventListener调用中添加passive:false来使preventDefault生效。所以我用这个来停止手机上的滚动:

function preventDefault(e){
    e.preventDefault();
}

function disableScroll(){
    document.body.addEventListener('touchmove', preventDefault, { passive: false });
}
function enableScroll(){
    document.body.removeEventListener('touchmove', preventDefault, { passive: false });
}

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.

使用JavaScript启用以下CSS将有所帮助。我不如这里的其他人好，但这对我很有用。

body {
    position: fixed;
    overflow-y: scroll;
}
