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。

网站我继承了,有一个滚动的链接。为了暂时禁用滚动单击特定按钮,这对我来说是有效的:

$(document).ready(function() {      
    $('button.class-name').click(function(event) {
        disableScroll();
        setTimeout(enableScroll, 500);  
    });
});


function disableScroll() {
    scrollTop =  window.pageYOffset || document.documentElement.scrollTop; 
    scrollLeft =  window.pageXOffset || document.documentElement.scrollLeft, 

    window.onscroll = function() { 
            window.scrollTo(scrollLeft, scrollTop); 
    };
}

function enableScroll() { 
    window.onscroll = function() {}; 
}

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。

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.

你可以这样做:

这样你就节省了“无关紧要”的内存,Position: fixed中的元素没有移动,因此不会影响你的设计本身。

CSS(使用CSS使您的生活和记忆更容易)

html[DisableScroll] {
    overflow-y: scroll;
}

html[DisableScroll] body {
    overflow-y: hidden;
    height: 100vh;
}

JS

var enableScroll = function () {
   document.documentElement
     .removeAttribute('DisableScroll');
}

e.g

//When you want to enable escroll just call this function; var enableScroll = function () { document.documentElement .removeAttribute('DisableScroll'); } setTimeout(() => { enableScroll(); }, 2000); *{ margin: 0px; padding: 0px } body{ height: 4000px; background: #141417 } html[DisableScroll] { overflow-y: scroll } html[DisableScroll] body { overflow-y: hidden; height: 100vh; } body>p{ color: #FBFBFD } div{ position: fixed; left: 0; right: 0; margin: auto; width: 270px; background: #FBFBFD; color: #141417; text-align: center } <!DOCTYPE html> <html lang="en" DisableScroll> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <div> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> </div> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> <p>@@@@</p><br> </body> </html>

这个解决方案将保持当前的滚动位置,而滚动是禁用的,不像有些跳回用户顶部。

它是基于galambalazs的答案,但支持触摸设备,并重构为一个单一的对象与jquery插件包装。
