这个怎么样?(如果你正在使用jQuery)

var $window = $(window);
var $body = $(window.document.body);

window.onscroll = function() {
    var overlay = $body.children(".ui-widget-overlay").first();

    // Check if the overlay is visible and restore the previous scroll state
    if (overlay.is(":visible")) {
        var scrollPos = $body.data("scroll-pos") || { x: 0, y: 0 };
        window.scrollTo(scrollPos.x, scrollPos.y);
    }
    else {
        // Just store the scroll state
        $body.data("scroll-pos", { x: $window.scrollLeft(), y: $window.scrollTop() });
    }
};

您可以阻止空格条滚动和隐藏浏览器滚动条:

$(document).keydown(function(event) {
    if (event.keyCode == 32) {
        return false;

    }
});

document.documentElement.style.overflow = 'hidden';
document.body.scroll = 'no';

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 });
}

对我来说，这并没有带来任何内容跳跃。

禁用滚动:

this.htmlBody = $('body')
this.scrollPos = document.documentElement.scrollTop
this.htmlBody.css('top', -this.scrollPos + 'px').addClass('disable-scroll')

重新启用滚动:

this.htmlBody.removeClass('disable-scroll')
$(window).scrollTop(this.scrollPos)

而CSS:

body.disable-scroll {
  position: fixed;
  width: 100%;
}

我在这里用了一个简单的技巧:

.no-scroll{
  overflow: hidden;
}

let toggle_scrolling_state = () => {
   element.classList.toggle("no-scroll");
}

然后当你想要停止滚动事件或…

Galambalazs的解决方案很棒!它在Chrome和Firefox中都非常适合我。它还可以扩展，以防止来自浏览器窗口的任何默认事件。 假设你在画布上做一个应用。你可以这样做:

var events = {
  preventDefault: function(e) {
    e = e || window.event;
    if (e.preventDefault) e.preventDefault();
    e.returnValue = false;  
  },

  //spacebar: 32, pageup: 33, pagedown: 34, end: 35, home: 36,
  //left: 37, up: 38, right: 39, down: 40
  keys: [32, 33, 34, 35, 36, 37, 38, 39, 40],
  keydown: function(e) {
    for (var i = events.keys.length; i--;) {
      if (e.keyCode === events.keys[i]) {
        events.preventDefault(e);
        return;
      }
    }
  },

  wheel: function(e) {
    events.preventDefault(e);
  },

  disable: function() {
    if (window.addEventListener) {
      window.addEventListener('DOMMouseScroll', events.wheel, false);
    }
    window.onmousewheel = document.onmousewheel = events.wheel;
    document.onkeydown = helpers.events.keydown;
  },

  enable: function() {
    if (window.removeEventListener) {
      window.removeEventListener('DOMMouseScroll', events.wheel, false);
    }
    window.onmousewheel = document.onmousewheel = document.onkeydown = null;  
  }
}

然后在你的应用程序中，假设你要处理你自己的事件，比如鼠标、键盘、触摸事件等等。你可以在鼠标进入画布时禁用默认事件，并在鼠标离开时重新启用它们:

function setMouseEvents(canvas) {
  var useCapture = false;

  //Mouse enter event
  canvas.addEventListener('mouseenter', function(event) {
    events.disable();
  }, useCapture);

  //Mouse leave event
  canvas.addEventListener('mouseleave', function(event) {
    events.enable();
  }, useCapture);
}

你甚至可以禁用右键菜单与此hack:

function disableRightClickMenu(canvas) {
  var my_gradient = canvas.context.createLinearGradient(0, 0, 0, 225);
  my_gradient.addColorStop(0, "white");
  my_gradient.addColorStop(1, "white");
  canvas.context.fillStyle = my_gradient;
  canvas.context.fillRect(0, 0, canvas.width, canvas.height);
  canvas.oncontextmenu = function() { return false; };
}
