作为变量，为了避免滚动或鼠标滚轮处理的性能问题，你可以使用如下代码:

css:

body.noscroll {
    overflow: hidden;
}
.scrollable {
    max-height: 200px;
    overflow-y: scroll;
    border: 1px solid #ccc;
}

html:

<div class="scrollable">
...A bunch of items to make the div scroll...
</div>
...A bunch of text to make the body scroll...

js:

var $document = $(document),
    $body = $('body'),
    $scrolable = $('.scrollable');

$scrolable.on({
          'mouseenter': function () {
            // add hack class to prevent workspace scroll when scroll outside
            $body.addClass('noscroll');
          },
          'mouseleave': function () {
            // remove hack class to allow scroll
            $body.removeClass('noscroll');
          }
        });

不要使用overflow: hidden;在身体。它会自动将所有内容滚动到顶部。也不需要JavaScript。利用overflow: auto;:

HTML结构

<div class="overlay">
    <div class="overlay-content"></div>
</div>

<div class="background-content">
    lengthy content here
</div>

样式

.overlay{
    position: fixed;
    top: 0px;
    left: 0px;
    right: 0px;
    bottom: 0px;
    background-color: rgba(0, 0, 0, 0.8);

    .overlay-content {
        height: 100%;
        overflow: scroll;
    }
}

.background-content{
    height: 100%;
    overflow: auto;
}

在这里玩演示。

编辑:代码依赖的例子

对于AngularJS，我定义了以下指令:

module.directive('isolateScrolling', function () {
  return {
    restrict: 'A',
      link: function (scope, element, attr) {
        element.bind('DOMMouseScroll', function (e) {
          if (e.detail > 0 && this.clientHeight + this.scrollTop == this.scrollHeight) {
            this.scrollTop = this.scrollHeight - this.clientHeight;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
          else if (e.detail < 0 && this.scrollTop <= 0) {
            this.scrollTop = 0;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
        });
        element.bind('mousewheel', function (e) {
          if (e.deltaY > 0 && this.clientHeight + this.scrollTop >= this.scrollHeight) {
            this.scrollTop = this.scrollHeight - this.clientHeight;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
          else if (e.deltaY < 0 && this.scrollTop <= 0) {
            this.scrollTop = 0;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }

          return true;
        });
      }
  };
});

然后将它添加到可滚动元素(下拉菜单ul):

<div class="dropdown">
  <button type="button" class="btn dropdown-toggle">Rename <span class="caret"></span></button>
  <ul class="dropdown-menu" isolate-scrolling>
    <li ng-repeat="s in savedSettings | objectToArray | orderBy:'name' track by s.name">
      <a ng-click="renameSettings(s.name)">{{s.name}}</a>
    </li>
  </ul>
</div>

在Chrome和Firefox上测试。当鼠标滚轮靠近(但不是在)滚动区域的顶部或底部时，Chrome的平滑滚动就会打败这个黑客。

我也遇到过类似的情况，我是这样解决的: 所有可滚动的元素使类可滚动。

$(document).on('wheel', '.scrollable', function(evt) {
  var offsetTop = this.scrollTop + parseInt(evt.originalEvent.deltaY, 10);
  var offsetBottom = this.scrollHeight - this.getBoundingClientRect().height - offsetTop;

  if (offsetTop < 0 || offsetBottom < 0) {
    evt.preventDefault();
  } else {
    evt.stopImmediatePropagation();
  }
});

stopImmediatePropagation()确保不从可滚动的子区域滚动父可滚动区域。

下面是它的一个普通JS实现: http://jsbin.com/lugim/2/edit?js,output

Angular JS指令

我必须封装一个角度指令。以下是其他答案的混搭。在Chrome和Internet Explorer 11上进行了测试。

var app = angular.module('myApp');

app.directive("preventParentScroll", function () {
    return {
        restrict: "A",
        scope: false,
        link: function (scope, elm, attr) {
            elm.bind('mousewheel', onMouseWheel);
            function onMouseWheel(e) {
                elm[0].scrollTop -= (e.wheelDeltaY || (e.originalEvent && (e.originalEvent.wheelDeltaY || e.originalEvent.wheelDelta)) || e.wheelDelta || 0);
                e.stopPropagation();
                e.preventDefault();
                e.returnValue = false;
            }
        }
    }
});

使用

<div prevent-parent-scroll>
    ...
</div>

希望这能帮助下一个从谷歌搜索到这里的人。

这在AngularJS中是有效的。 在Chrome和Firefox上测试。

.directive('stopScroll', function () {
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            element.bind('mousewheel', function (e) {
                var $this = $(this),
                    scrollTop = this.scrollTop,
                    scrollHeight = this.scrollHeight,
                    height = $this.height(),
                    delta = (e.type == 'DOMMouseScroll' ?
                    e.originalEvent.detail * -40 :
                        e.originalEvent.wheelDelta),
                    up = delta > 0;

                var prevent = function() {
                    e.stopPropagation();
                    e.preventDefault();
                    e.returnValue = false;
                    return false;
                };

                if (!up && -delta > scrollHeight - height - scrollTop) {
                    // Scrolling down, but this will take us past the bottom.
                    $this.scrollTop(scrollHeight);
                    return prevent();
                } else if (up && delta > scrollTop) {
                    // Scrolling up, but this will take us past the top.
                    $this.scrollTop(0);
                    return prevent();
                }
            });
        }
    };
})
