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)
});

我找到了一个更好,但有问题的方法,结合了sdleihssirhc的想法:

window.onscroll = function() {
    window.scrollTo(window.scrollX, window.scrollY);
    //Or
    //window.scroll(window.scrollX, window.scrollY);
    //Or Fallback
    //window.scrollX=window.scrollX;
    //window.scrollY=window.scrollY;
};

我没有测试它,但我稍后会编辑,让你们都知道。我有85%的把握它能在主流浏览器上运行。

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.

我知道这是一个老问题,但我不得不做一些非常相似的事情,在花了一段时间寻找答案并尝试了不同的方法后,我最终使用了一个非常简单的解决方案。

我的问题非常相似,几乎相同,唯一的区别是我不需要实际显示滚动条-我只需要确保它的宽度仍然被使用,所以当我的覆盖显示时,页面的宽度不会改变。

当我开始滑动覆盖到屏幕,我做:

$('body').addClass('stop-scrolling').css('margin-right', 8);

在我将覆盖层从屏幕上滑动后,我这样做:

$('body').removeClass('stop-scrolling').css('margin-right', 0);

重要:这是完美的工作,因为我的叠加是绝对定位,对:0px时可见。

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';

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%;
}
