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.

我也有同样的问题，下面是我处理它的方法。

/* file.js */
var body = document.getElementsByTagName('body')[0];
//if window dont scroll
body.classList.add("no-scroll");
//if window scroll
body.classList.remove("no-scroll");

/* file.css */
.no-scroll{
  position: fixed;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}

希望这对你有所帮助。

另一个解决方案:

body {
    overflow-y: scroll;
    width: 100%;
    margin: 0 auto;
}

这样你总是有一个垂直的滚动条，但由于我的大部分内容都比视口长，这对我来说是可以的。内容是中心与一个单独的div，但没有设置边缘再次在身体我的内容将留在左边。

这是我用来显示弹出式/模态的两个函数:

var popup_bodyTop = 0;
var popup_bodyLeft = 0;

function popupShow(id)
{
    $('#'+ id).effect('fade');
    $('#popup-overlay').effect('fade');

    // remember current scroll-position
    // because when setting/unsetting position: fixed to body
    // the body would scroll to 0,0
    popup_bodyLeft = $(document).scrollLeft();
    popup_bodyTop  = $(document).scrollTop();

    // invert position
    var x = - popup_bodyLeft;
    var y = - popup_bodyTop;

    $('body').css('position', 'fixed');
    $('body').css('top', y.toString() +'px');
    $('body').css('left', x.toString() +'px');
}

function popupHide(id)
{
    $('#'+ id).effect('fade');
    $('#popup-overlay').effect('fade');
    $('body').css('position', '');
    $('html, body').scrollTop(popup_bodyTop);
    $('html, body').scrollLeft(popup_bodyLeft);
}

结果:不可滚动的背景和没有重新定位的内容，因为左边的滚动条。测试与当前的FF, Chrome和IE 10。

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;
}

我发现改变身体的风格是没有必要的。

我们唯一需要做的就是防止整个文档(html元素)出现y滚动。

我们可以用Javascript来创建和销毁样式表。我是这样做的:

https://jsfiddle.net/3os72ryk/

var scroll_style_element;

function disable_scrolling(){
    
  // Create a style sheet we will only use to disable scrolling :
  scroll_style_element = document.createElement('style');
  document.head.appendChild(scroll_style_element);
  const scroll_style_sheet = scroll_style_element.sheet;
    
  scroll_style_sheet.insertRule('html{height:100%;overflow-y:hidden;}', scroll_style_sheet.cssRules.length);
}

function enable_scrolling(){
  if( scroll_style_element ) document.head.removeChild(scroll_style_element);
}

非常有兴趣知道是否有人发现这种方法有问题，所以如果你发现了，请在下面评论。
