Prevent BODY from scrolling when a modal is opened
JavascriptJqueryCssScrollJavascript Problem Overview
I want my body to stop scrolling when using the mousewheel while the Modal (from http://twitter.github.com/bootstrap) on my website is opened.
I've tried to call the piece of javascript below when the modal is opened but without success
$(window).scroll(function() { return false; });
AND
$(window).live('scroll', function() { return false; });
Please note our website dropped support for IE6, IE7+ needs to be compatible though.
Javascript Solutions
Solution 1 - Javascript
Bootstrap's modal automatically adds the class modal-open to the body when a modal dialog is shown and removes it when the dialog is hidden. You can therefore add the following to your CSS:
body.modal-open {
overflow: hidden;
}
You could argue that the code above belongs to the Bootstrap CSS code base, but this is an easy fix to add it to your site.
Update 8th feb, 2013
This has now stopped working in Twitter Bootstrap v. 2.3.0 -- they no longer add the modal-open class to the body.
A workaround would be to add the class to the body when the modal is about to be shown, and remove it when the modal is closed:
$("#myModal").on("show", function () {
$("body").addClass("modal-open");
}).on("hidden", function () {
$("body").removeClass("modal-open")
});
Update 11th march, 2013
Looks like the modal-open class will return in Bootstrap 3.0, explicitly for the purpose of preventing the scroll:
> Reintroduces .modal-open on the body (so we can nuke the scroll there)
See this: https://github.com/twitter/bootstrap/pull/6342 - look at the Modal section.
Solution 2 - Javascript
The accepted answer doesn't work on mobile (iOS 7 w/ Safari 7, at least) and I don't want MOAR JavaScript running on my site when CSS will do.
This CSS will prevent the background page from scrolling under the modal:
body.modal-open {
overflow: hidden;
position: fixed;
}
However, it also has a slight side-affect of essentially scrolling to the top. position:absolute resolves this but, re-introduces the ability to scroll on mobile.
If you know your viewport (my plugin for adding viewport to the <body>) you can just add a css toggle for the position.
body.modal-open {
// block scroll for mobile;
// causes underlying page to jump to top;
// prevents scrolling on all screens
overflow: hidden;
position: fixed;
}
body.viewport-lg {
// block scroll for desktop;
// will not jump to top;
// will not prevent scroll on mobile
position: absolute;
}
I also add this to prevent the underlying page from jumping left/right when showing/hiding modals.
body {
// STOP MOVING AROUND!
overflow-x: hidden;
overflow-y: scroll !important;
}
Solution 3 - Javascript
Simply hide the body overflow and it makes body not scrolling. When you hide the modal, revert it to automatic.
Here is the code:
$('#adminModal').modal().on('shown', function(){
$('body').css('overflow', 'hidden');
}).on('hidden', function(){
$('body').css('overflow', 'auto');
})
Solution 4 - Javascript
You need to go beyond @charlietfl's answer and account for scrollbars, otherwise you may see a document reflow.
Opening the modal:
-
Record the
bodywidth -
Set
bodyoverflow tohidden -
Explicitly set the body width to what it was in step 1.
var $body = $(document.body); var oldWidth = $body.innerWidth(); $body.css("overflow", "hidden"); $body.width(oldWidth);
Closing the modal:
-
Set
bodyoverflow toauto -
Set
bodywidth toautovar $body = $(document.body); $body.css("overflow", "auto"); $body.width("auto");

Solution 5 - Javascript
You could try setting body size to window size with overflow: hidden when modal is open
Solution 6 - Javascript
Warning: The option below is not relevant to Bootstrap v3.0.x, as scrolling in those versions has been explicitly confined to the modal itself. If you disable wheel events you may inadvertently prevent some users from viewing the content in modals that have heights greater than the viewport height.
Yet Another Option: Wheel Events
The scroll event is not cancelable. However it is possible to cancel the mousewheel and wheel events. The big caveat is that not all legacy browsers support them, Mozilla only recently adding support for the latter in Gecko 17.0. I don't know the full spread, but IE6+ and Chrome do support them.
Here's how to leverage them:
$('#myModal')
.on('shown', function () {
$('body').on('wheel.modal mousewheel.modal', function () {
return false;
});
})
.on('hidden', function () {
$('body').off('wheel.modal mousewheel.modal');
});
JSFiddle
Solution 7 - Javascript
Try this one:
.modal-open {
overflow: hidden;
position:fixed;
width: 100%;
height: 100%;
}
it worked for me. (supports IE8)

Solution 9 - Javascript
Couldn't make it work on Chrome just by changing CSS, because I didn't want the page to scroll back to the top. This worked fine:
$("#myModal").on("show.bs.modal", function () {
var top = $("body").scrollTop(); $("body").css('position','fixed').css('overflow','hidden').css('top',-top).css('width','100%').css('height',top+5000);
}).on("hide.bs.modal", function () {
var top = $("body").position().top; $("body").css('position','relative').css('overflow','auto').css('top',0).scrollTop(-top);
});
Solution 10 - Javascript
Adding the class 'is-modal-open' or modifying style of body tag with javascript is okay and it will work as supposed to. But the problem we gonna face is when the body becomes overflow:hidden, it will jump to the top, ( scrollTop will become 0 ). This will become a usability issue later.
As a solution for this problem, instead of changing body tag overflow:hidden change it on html tag
$('#myModal').on('shown.bs.modal', function () {
$('html').css('overflow','hidden');
}).on('hidden.bs.modal', function() {
$('html').css('overflow','auto');
});
Solution 11 - Javascript
As of November 2017 Chrome Introduced a new css property
overscroll-behavior: contain;
which solves this problem although as of writing has limited cross browser support.
see below links for full details and browser support
Solution 12 - Javascript
>For Bootstrap, you might try this (working on Firefox, Chrome and Microsoft Edge) :
body.modal-open {
overflow: hidden;
position:fixed;
width: 100%;
}
Hope this helps...
Solution 13 - Javascript
I'm not sure about this code, but it's worth a shot.
In jQuery:
$(document).ready(function() {
$(/* Put in your "onModalDisplay" here */)./* whatever */(function() {
$("#Modal").css("overflow", "hidden");
});
});
As I said before, I'm not 100% sure but try anyway.
Solution 14 - Javascript
The best solution is the css-only body{overflow:hidden} solution used by most of these answers. Some answers provide a fix that also prevent the "jump" caused by the disappearing scrollbar; however, none were too elegant. So, I wrote these two functions, and they seem to work pretty well.
var $body = $(window.document.body);
function bodyFreezeScroll() {
var bodyWidth = $body.innerWidth();
$body.css('overflow', 'hidden');
$body.css('marginRight', ($body.css('marginRight') ? '+=' : '') + ($body.innerWidth() - bodyWidth))
}
function bodyUnfreezeScroll() {
var bodyWidth = $body.innerWidth();
$body.css('marginRight', '-=' + (bodyWidth - $body.innerWidth()))
$body.css('overflow', 'auto');
}
Check out this jsFiddle to see it in use.
Solution 15 - Javascript
I'm not 100% sure this will work with Bootstrap but worth a try - it worked with Remodal.js which can be found on github: <http://vodkabears.github.io/remodal/> and it would make sense for the methods to be pretty similar.
To stop the page jumping to the top and also prevent the right shift of content add a class to the body when the modal is fired and set these CSS rules:
body.with-modal {
position: static;
height: auto;
overflow-y: hidden;
}
It's the position:static and the height:auto that combine to stop the jumping of content to the right. The overflow-y:hidden; stops the page from being scrollable behind the modal.
Solution 16 - Javascript
React , if you are looking for
useEffect in the modal that is getting popedup
useEffect(() => {
document.body.style.overflowY = 'hidden';
return () =>{
document.body.style.overflowY = 'auto';
}
}, [])
Solution 17 - Javascript
Many suggest "overflow: hidden" on the body, which will not work (not in my case at least), since it will make the website scroll to the top.
This is the solution that works for me (both on mobile phones and computers), using jQuery:
$('.yourModalDiv').bind('mouseenter touchstart', function(e) {
var current = $(window).scrollTop();
$(window).scroll(function(event) {
$(window).scrollTop(current);
});
});
$('.yourModalDiv').bind('mouseleave touchend', function(e) {
$(window).off('scroll');
});
This will make the scrolling of the modal to work, and prevent the website from scrolling at the same time.
Solution 18 - Javascript
I had to set the viewport-height to get this working perfectly
body.modal-open {
height: 100vh;
overflow: hidden;
}
Solution 19 - Javascript
You could use the following logic, I tested it and it works(even in IE)
<html>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
var currentScroll=0;
function lockscroll(){
$(window).scrollTop(currentScroll);
}
$(function(){
$('#locker').click(function(){
currentScroll=$(window).scrollTop();
$(window).bind('scroll',lockscroll);
})
$('#unlocker').click(function(){
currentScroll=$(window).scrollTop();
$(window).unbind('scroll');
})
})
</script>
<div>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>

Solution 20 - Javascript
Based on this fiddle: http://jsfiddle.net/dh834zgw/1/
the following snippet (using jquery) will disable the window scroll:
var curScrollTop = $(window).scrollTop();
$('html').toggleClass('noscroll').css('top', '-' + curScrollTop + 'px');
And in your css:
html.noscroll{
position: fixed;
width: 100%;
top:0;
left: 0;
height: 100%;
overflow-y: scroll !important;
z-index: 10;
}
Now when you remove the modal, don't forget to remove the noscroll class on the html tag:
$('html').toggleClass('noscroll');
Solution 21 - Javascript
Sadly none of the answers above fixed my issues.
In my situation, the web page originally has a scroll bar. Whenever I click the modal, the scroll bar won't disappear and the header will move to right a bit.
Then I tried to add .modal-open{overflow:auto;} (which most people recommended). It indeed fixed the issues: the scroll bar appears after I open the modal. However, another side effect comes out which is that "background below the header will move to the left a bit, together with another long bar behind the modal"
Luckily, after I add {padding-right: 0 !important;}, everything is fixed perfectly. Both the header and body background didn't move and the modal still keeps the scrollbar.
Hope this can help those who are still stuck with this issue. Good luck!
Solution 22 - Javascript
This worked for me:
$("#mymodal").mouseenter(function(){
$("body").css("overflow", "hidden");
}).mouseleave(function(){
$("body").css("overflow", "visible");
});
Solution 23 - Javascript
Most of the pieces are here, but I don't see any answer that puts it all together.
The problem is threefold.
(1) prevent the scroll of the underlying page
$('body').css('overflow', 'hidden')
(2) and remove the scroll bar
var handler = function (e) { e.preventDefault() }
$('.modal').bind('mousewheel touchmove', handler)
(3) clean up when the modal is dismissed
$('.modal').unbind('mousewheel touchmove', handler)
$('body').css('overflow', '')
If the modal is not full-screen then apply the .modal bindings to a full screen overlay.
Solution 24 - Javascript
My solution for Bootstrap 3:
.modal {
overflow-y: hidden;
}
body.modal-open {
margin-right: 0;
}
because for me the only overflow: hidden on the body.modal-open class did not prevent the page from shifting to the left due to the original margin-right: 15px.
Solution 25 - Javascript
I just done it this way ...
$('body').css('overflow', 'hidden');
But when the scroller dissapeared it moved everything right 20px, so i added
$('body').css('margin-right', '20px');
straight after it.
Works for me.
Solution 26 - Javascript
If modal are 100% height/width "mouseenter/leave" will work to easily enable/disable scrolling. This really worked out for me:
var currentScroll=0;
function lockscroll(){
$(window).scrollTop(currentScroll);
}
$("#myModal").mouseenter(function(){
currentScroll=$(window).scrollTop();
$(window).bind('scroll',lockscroll);
}).mouseleave(function(){
currentScroll=$(window).scrollTop();
$(window).unbind('scroll',lockscroll);
});
Solution 27 - Javascript
I had a sidebar that was generated by checkbox hack. But the main idea is to save the document scrollTop and not to change it during scrolling the window.
I just didn't like the page jumping when body becomes 'overflow: hidden'.
window.addEventListener('load', function() {
let prevScrollTop = 0;
let isSidebarVisible = false;
document.getElementById('f-overlay-chkbx').addEventListener('change', (event) => {
prevScrollTop = window.pageYOffset || document.documentElement.scrollTop;
isSidebarVisible = event.target.checked;
window.addEventListener('scroll', (event) => {
if (isSidebarVisible) {
window.scrollTo(0, prevScrollTop);
}
});
})
});
Solution 28 - Javascript
Since for me this problem presented mainly on iOS, I provide the code to fix that only on iOS:
if(!!navigator.platform && /iPad|iPhone|iPod/.test(navigator.platform)) {
var $modalRep = $('#modal-id'),
startScrollY = null,
moveDiv;
$modalRep.on('touchmove', function(ev) {
ev.preventDefault();
moveDiv = startScrollY - ev.touches[0].clientY;
startScrollY = ev.touches[0].clientY;
var el = $(ev.target).parents('#div-that-scrolls');
// #div-that-scrolls is a child of #modal-id
el.scrollTop(el.scrollTop() + moveDiv);
});
$modalRep.on('touchstart', function(ev) {
startScrollY = ev.touches[0].clientY;
});
}
Solution 29 - Javascript
None of the above answers worked perfectly for me. So I found another way which works well.
Just add a scroll.(namespace) listener and set scrollTop of the document to the latest of it's value...
and also remove the listener in your close script.
// in case of bootstrap modal example:
$('#myModal').on('shown.bs.modal', function () {
var documentScrollTop = $(document).scrollTop();
$(document).on('scroll.noScroll', function() {
$(document).scrollTop(documentScrollTop);
return false;
});
}).on('hidden.bs.modal', function() {
$(document).off('scroll.noScroll');
});
update
seems, this does not work well on chrome. any suggestion to fix it ?

Basically when the modal is opened it will add a negative top for the body to maintain the window scroll position before opening the modal. When closing the modal the window scroll is kept using the same value applied for the top when opening. This approach prevents body scroll.

I am using this vanilla js function to add "modal-open" class to the body. (Based on smhmic's answer)
function freezeScroll(show, new_width)
{
var innerWidth = window.innerWidth,
clientWidth = document.documentElement.clientWidth,
new_margin = ((show) ? (new_width + innerWidth - clientWidth) : new_width) + "px";
document.body.style.marginRight = new_margin;
document.body.className = (show) ? "modal-open" : "";
};

Hiding the overflow and fixing the position does the trick however with my fluid design it would fix it past the browsers width, so a width:100% fixed that.
body.modal-open{overflow:hidden;position:fixed;width:100%}

You should add overflow: hidden in HTML for a better cross-platform performance.
I would use
html.no-scroll {
overflow: hidden;
}
Solution 38 - Javascript
$('.modal').on('shown.bs.modal', function (e) {
$('body').css('overflow-y', 'hidden');
});
$('.modal').on('hidden.bs.modal', function (e) {
$('body').css('overflow-y', '');
});

A small note for those in SharePoint 2013. The body already has overflow: hidden. What you are looking for is to set overflow: hidden on div element with id s4-workspace, e.g.
var body = document.getElementById('s4-workspace');
body.className = body.className+" modal-open";

worked for me
$('#myModal').on({'mousewheel': function(e)

Solution 41 - Javascript
The above occurs when you use a modal inside another modal. When I open a modal inside another modal, the closing of the latter removes the class modal-open from the body. The fix of the issue depends on how you close the latter modal.
If you close the modal with html like,
<button type="button" class="btn" data-dismiss="modal">Close</button>
Then you have to add a listener like this,
$(modalSelector).on("hidden.bs.modal", function (event) {
event.stopPropagation();
$("body").addClass("modal-open");
return false;
});
If you close the modal using javascript like,
$(modalSelector).modal("hide");
Then you have to run the command some time after like this,
setInterval(function(){$("body").addClass("modal-open");}, 300);
Solution 42 - Javascript
Why not to do that as Bulma does? When modal is-active then add to html their class .is-clipped which is overflow: hidden!important; And thats it.
Edit: Okey, Bulma has this bug, so you must add also other things like
html.is-modal-active {
overflow: hidden !important;
position: fixed;
width: 100%;
}

Here's my vanilla JS solution based on @jpap jquery:

bodyElement.style.width = width + 'px';
// unlock body scroll
bodyElement.classList.remove('overflow-hidden');
bodyElement.style.width = 'auto';

} else {
document.body.style.overflow = "visible";

I read most answers with a focus on React.
Best solution for my React functional component was to use solution provided originally by @arcticmatt
I included some improvements that were mentioned in other answers in the code example bellow (pay attention to the useEffect definition):
import {useEffect, useRef} from "react";
export default function PopoverMenu({className, handleClose, children}) {
const selfRef = useRef(undefined);
useEffect(() => {
const isPopoverOpenned = selfRef.current?.style.display !== "none";
const focusedElement = document?.activeElement;
const scrollPosition = {x: window.scrollX, y: window.scrollY};
if (isPopoverOpenned) {
preventDocBodyScrolling();
} else {
restoreDocBodyScrolling();
}
function preventDocBodyScrolling() {
const width = document.body.clientWidth;
const hasVerticalScrollBar = (window.innerWidth > document.documentElement.clientWidth);
document.body.style.overflowX = "hidden";
document.body.style.overflowY = hasVerticalScrollBar ? "scroll" : "";
document.body.style.width = `${width}px`;
document.body.style.position = "fixed";
}
function restoreDocBodyScrolling() {
document.body.style.overflowX = "";
document.body.style.overflowY = "";
document.body.style.width = "";
document.body.style.position = "";
focusedElement?.focus();
window.scrollTo(scrollPosition.x, scrollPosition.y);

return () => {
restoreDocBodyScrolling(); // cleanup on unmount

I found a working solution after doing some 8-10 hours research on StackOverflow itself.
The breakthrough
$('.modal').is(':visible');
So I have built a function to check if any modal is open which will periodically add class modal-open* to the
setInterval(function()
{
if($('.modal').is(':visible')===true)
{
$("body").addClass("modal-open");
}
else
{
$("body").removeClass("modal-open");
}
},200);
> The reason to use $(".modal") here is because all modals (in Bootstrap) use class modal (fade/show is as per the state)
So my modals are now running perfectly without the body getting scrolled.
This is a bug/unheard issue in GitHub as well but nobody's bothered.
Solution 48 - Javascript
HTML:
<body onscroll="stop_scroll()">
javascript:
function stop_scroll(){
scroll(0,0) ;
}
If you set a flag (bool) inside stop_scroll(), you can decide when to engage it (if you want it only temporarely).
This will reset scrolling every time some element overflows the body boundaries and the windows tends to scroll (this is totally independent of scrollbars; overflow : hidden has nothing to do with it).
