我正在使用scrollTo jQuery插件,想知道是否有可能通过Javascript暂时禁用窗口元素上的滚动?我想禁用滚动的原因是,当你滚动而scrollTo是动画,它变得非常难看;)

当然,我可以做$("body").css("overflow", "hidden");然后当动画停止时把它放回自动,但如果滚动条仍然可见但不活跃会更好。

根据你想要使用移除的滚动来实现什么,你可以只修复你想要移除滚动的元素(单击,或任何其他你想要临时禁用滚动的触发器)

我正在寻找一个“临时无滚动”的解决方案,这解决了我的需要

创建一个班级

.fixed{
    position: fixed;
}

然后用Jquery

var someTrigger = $('#trigger'); //a trigger button
var contentContainer = $('#content'); //element I want to temporarily remove scroll from

contentContainer.addClass('notfixed'); //make sure that the element has the "notfixed" class

//Something to trigger the fixed positioning. In this case we chose a button.
someTrigger.on('click', function(){

    if(contentContainer.hasClass('notfixed')){
        contentContainer.removeClass('notfixed').addClass('fixed');

    }else if(contentContainer.hasClass('fixed')){
        contentContainer.removeClass('fixed').addClass('notfixed');
    };
});

我发现这是一个非常简单的解决方案,适用于所有浏览器,也适用于便携式设备(如iphone,平板电脑等)。由于元素是临时固定的,所以没有滚动:)

注意!根据contentContainer元素的位置,你可能需要从左边调整它。这可以很容易地通过添加一个css左值的元素时,固定类是活跃的

contentContainer.css({
    'left': $(window).width() - contentContainer.width()/2 //This would result in a value that is the windows entire width minus the element we want to "center" divided by two (since it's only pushed from one side)
});

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;
}

只需在body中添加一个类即可:

.stop-scrolling {
  height: 100%;
  overflow: hidden;
}

添加类,然后删除当你想重新启用滚动,测试在IE, FF, Safari和Chrome。

$('body').addClass('stop-scrolling')

对于移动设备,你需要处理touchmove事件:

$('body').bind('touchmove', function(e){e.preventDefault()})

并取消绑定以重新启用滚动。在iOS6和Android 2.3.3测试

$('body').unbind('touchmove')

无法取消滚动事件。但是你可以通过取消这些交互事件来实现: 鼠标和触摸滚动和与滚动相关的按钮。

(工作演示)

// left: 37, up: 38, right: 39, down: 40,
// spacebar: 32, pageup: 33, pagedown: 34, end: 35, home: 36
var keys = {37: 1, 38: 1, 39: 1, 40: 1};

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

function preventDefaultForScrollKeys(e) {
  if (keys[e.keyCode]) {
    preventDefault(e);
    return false;
  }
}

// modern Chrome requires { passive: false } when adding event
var supportsPassive = false;
try {
  window.addEventListener("test", null, Object.defineProperty({}, 'passive', {
    get: function () { supportsPassive = true; } 
  }));
} catch(e) {}

var wheelOpt = supportsPassive ? { passive: false } : false;
var wheelEvent = 'onwheel' in document.createElement('div') ? 'wheel' : 'mousewheel';

// call this to Disable
function disableScroll() {
  window.addEventListener('DOMMouseScroll', preventDefault, false); // older FF
  window.addEventListener(wheelEvent, preventDefault, wheelOpt); // modern desktop
  window.addEventListener('touchmove', preventDefault, wheelOpt); // mobile
  window.addEventListener('keydown', preventDefaultForScrollKeys, false);
}

// call this to Enable
function enableScroll() {
  window.removeEventListener('DOMMouseScroll', preventDefault, false);
  window.removeEventListener(wheelEvent, preventDefault, wheelOpt); 
  window.removeEventListener('touchmove', preventDefault, wheelOpt);
  window.removeEventListener('keydown', preventDefaultForScrollKeys, false);
}

更新:固定Chrome桌面和现代移动浏览器被动监听器

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
