基于Cheyenne Forbes的回答，以及我在这里通过fcalderan找到的答案:只是禁用滚动而不是隐藏它? 并修复了Hallodom的滚动条消失的问题

CSS:

.preventscroll{
    position: fixed;
    overflow-y:scroll;
}

JS:

whatever.onclick = function(){
    $('body').addClass('preventscroll');
}
whatevertoclose.onclick = function(){
    $('body').removeClass('preventscroll');
}

这段代码确实会跳到页面的顶部，但我认为fcalderan的代码有一个解决方案。

在我看来，取消事件是一个可怕的方法:/

相反，我使用position: fixed;上图:-scrollTop ();在下面。

演示:https://jsfiddle.net/w9w9hthy/5/

从我的jQuery弹出项目:https://github.com/seahorsepip/jPopup

//Freeze page content scrolling
function freeze() {
    if($("html").css("position") != "fixed") {
        var top = $("html").scrollTop() ? $("html").scrollTop() : $("body").scrollTop();
        if(window.innerWidth > $("html").width()) {
            $("html").css("overflow-y", "scroll");
        }
        $("html").css({"width": "100%", "height": "100%", "position": "fixed", "top": -top});
    }
}

//Unfreeze page content scrolling
function unfreeze() {
    if($("html").css("position") == "fixed") {
        $("html").css("position", "static");
        $("html, body").scrollTop(-parseInt($("html").css("top")));
        $("html").css({"position": "", "width": "", "height": "", "top": "", "overflow-y": ""});
    }
}

这段代码考虑了宽度、高度、滚动条和页面跳转问题。

上述代码可能解决的问题:

宽度，当设置位置固定的HTML元素宽度可以小于100% 高度，同上 滚动条，当设置位置固定时，页面内容不再有滚动条，即使它在水平页面跳转之前有滚动条 页面跳转，当设置位置固定时，页面滚动顶部不再有效，导致垂直页面跳转

如果任何人对上面的页面冻结/解冻代码有任何改进，请告诉我，这样我就可以将这些改进添加到我的项目中。

我一直在寻找这个问题的解决方案，但对上面的任何解决方案都不满意(在写这个答案时)，所以我想出了这个解决方案。

CSS

.scrollDisabled {   
    position: fixed;
    margin-top: 0;// override by JS to use acc to curr $(window).scrollTop()
    width: 100%;
}

JS

var y_offsetWhenScrollDisabled=0;

function disableScrollOnBody(){
    y_offsetWhenScrollDisabled= $(window).scrollTop();
    $('body').addClass('scrollDisabled').css('margin-top', -y_offsetWhenScrollDisabled);
}
function enableScrollOnBody(){
    $('body').removeClass('scrollDisabled').css('margin-top', 0);
    $(window).scrollTop(y_offsetWhenScrollDisabled);
}

var winX = null;
var winY = null;

window.addEventListener('scroll', function () {
    if (winX !== null && winY !== null) {
        window.scrollTo(winX, winY);
    }
});

function disableWindowScroll() {
    winX = window.scrollX;
    winY = window.scrollY;
}

function enableWindowScroll() {
    winX = null;
    winY = null;
}

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.

我在触摸设备上也有类似的问题。向元素添加“touch-action: none”解决了这个问题。
