How to prevent page scrolling when scrolling a DIV element

Question

I have reviewed and tested the various functions for preventing the body ability to scroll whilst inside a div and have combined a function that should work       scrollable   mouseenter function            body   bind  mousewheel DOMMouseScroll   function             return false                this  bind  mousewheel DOMMouseScroll   function             return true                  scrollable   mouseleave function            body   bind  mousewheel DOMMouseScroll   function             return true                 This is stopping all scrolling where as I want scrolling to still be possible inside the container This is also not deactivating on mouse leave   Any ideas  or better ways of doing this

Update 2  My solution is based on disabling the browser s native scrolling altogether  when cursor is inside the DIV  and then manually scrolling the DIV with JavaScript  by setting its  scrollTop property   An alternative and IMO better approach would be to only selectively disable the browser s scrolling in order to prevent the page scroll  but not the DIV scroll  Check out Rudie s answer below which demonstrates this solution      Here you go        scrollable    on   mousewheel DOMMouseScroll   function   e         var e0   e originalEvent          delta   e0 wheelDelta    -e0 detail       this scrollTop      delta  lt  0   1   -1     30      e preventDefault          Live demo  https   jsbin com howojuq edit js output  So you manually set the scroll position and then just prevent the default behavior  which would be to scroll the DIV or whole web-page    Update 1  As Chris noted in the comments below  in newer versions of jQuery  the delta information is nested within the  originalEvent object  i e  jQuery does not expose it in its custom Event object anymore and we have to retrieve it from the native Event object instead

I think it s possible to cancel the mousescroll event sometimes  http   jsfiddle net rudiedirkx F8qSq show    elem on  wheel   function e        var d   e originalEvent deltaY          dir   d  lt  0    up     down           stop    dir     up   amp  amp  this scrollTop    0                      dir     down   amp  amp  this scrollTop    this scrollHeight-this offsetHeight       stop  amp  amp  e preventDefault          Inside the event handler  you ll need to know    scrolling direction d   e originalEvent deltaY  dir   d  lt  0    up     down  because a positive number means scrolling down scroll position scrollTop for top  scrollHeight - scrollTop - offsetHeight for bottom   If you re   scrolling up  and top   0  or scrolling down  and bottom   0    cancel the event  e preventDefault    and maybe even e stopPropagation      I think it s better to not override the browser s scrolling behaviour  Only cancel it when applicable   It s probablt not perfectly xbrowser  but it can t be very hard  Maybe Mac s dual scroll direction is tricky though

I needed to add this event to multiple elements that might have a scrollbar  For the cases where no scrollbar was present  the main scrollbar didn t work as it should  So i made a small change to    ime code as follows        scrollable    on   mousewheel DOMMouseScroll   function   e         if   this  prop  scrollHeight    gt    this  height                  var e0   e originalEvent  delta   e0 wheelDelta    -e0 detail           this scrollTop      delta  lt  0   1   -1     30          e preventDefault                       Now  only elements with a scrollbar will prevent the main scroll from begin stopped

A less hacky solution  in my opinion is to set overflow hidden on the body when you mouse over the scrollable div  This will prevent the body from scrolling  but an unwanted  jumping  effect will occur  The following solution works around that   jQuery   scrollable        mouseenter function e               get body width now         var body width   jQuery  body   width               set overflow hidden on body  this will prevent it scrolling         jQuery  body   css  overflow    hidden                get new body width  no scrollbar now  so it will be bigger         var new body width   jQuery  body   width               set the difference between new width and old width as padding to prevent jumps                                              jQuery  body   css  padding-right    new body width - body width   px                mouseleave function e            jQuery  body   css               overflow   auto               padding-right   0px                       You could make your code smarter if needed  For example  you could test if the body already has a padding and if yes  add the new padding to that

Pure javascript version of Vidas s answer  el  is the DOM node of the plane you are scrolling   function onlyScrollElement event  el         var delta   event wheelDelta    -event detail      el  scrollTop     delta  lt  0   1   -1    10      event preventDefault        Make sure you dont attach the even multiple times  Here is an example   var ul    document getElementById  yo-list       IE9  Chrome  Safari  Opera ul  removeEventListener  mousewheel   onlyScrollElement   ul  addEventListener  mousewheel   onlyScrollElement      Firefox ul  removeEventListener  DOMMouseScroll   onlyScrollElement   ul  addEventListener  DOMMouseScroll   onlyScrollElement     Word of caution  the function there needs to be a constant  if you reinitialize the function each time before attaching it  ie  var func   function       the removeEventListener will not work

You can do this without JavaScript  You can set the style on both divs to position  fixed and overflow-y  auto  You may need to make one of them higher than the other by setting its z-index  if they overlap    Here s a basic example on CodePen

just offering this up as a possible solution if you don t think the user will have a negative experience on the obvious change  I simply changed the body s class of overflow to hidden when the mouse was over the target div  then I changed the body s div to hidden overflow when the mouse leaves   Personally I don t think it looks bad  my code could use toggle to make it cleaner  and there are obvious benefits for making this effect possible without the user being aware  So this is probably the hackish-last-resort answer      listen mouse on and mouse off for the button pxMenu addEventListener  mouseover   toggleA1   pxOptContainer addEventListener  mouseout   toggleA2     show   hide the pixel option menu function toggleA1      pxOptContainer style display    flex     body style overflow    hidden     function toggleA2      pxOptContainer style display    none     body style overflow    hidden scroll

If you don t care about the compatibility with older IE versions   lt  8   you could make a custom jQuery plugin and then call it on the overflowing element   This solution has an advantage over the one   ime Vidas proposed  as it doesn t overwrite the scrolling behavior - it just blocks it when appropriate     fn isolatedScroll   function         this bind  mousewheel DOMMouseScroll   function  e            var delta   e wheelDelta     e originalEvent  amp  amp  e originalEvent wheelDelta     -e detail              bottomOverflow   this scrollTop     this  outerHeight   - this scrollHeight  gt   0              topOverflow   this scrollTop  lt   0           if   delta  lt  0  amp  amp  bottomOverflow      delta  gt  0  amp  amp  topOverflow                 e preventDefault                          return this          scrollable   isolatedScroll

In the solution above there is a little mistake regarding Firefox  In Firefox  DOMMouseScroll  event has no e detail property to get this property you should write the following  e originalEvent detail    Here is a working solution for Firefox     fn isolatedScroll   function         this on  mousewheel DOMMouseScroll   function  e            var delta   e wheelDelta     e originalEvent  amp  amp  e originalEvent wheelDelta     -e originalEvent detail              bottomOverflow    this scrollTop     this  outerHeight   - this scrollHeight   gt   0              topOverflow   this scrollTop  lt   0           if   delta  lt  0  amp  amp  bottomOverflow      delta  gt  0  amp  amp  topOverflow                 e preventDefault                          return this

Here is my solution I ve used in applications   I disabled the body overflow and placed the entire website html inside container div s  The website containers have overflow and therefore the user may scroll the page as expected   I then created a sibling div   Prevent  with a higher z-index that covers the entire website  Since  Prevent has a higher z-index  it overlaps the website container  When  Prevent is visible the mouse is no longer hovering the website containers  so scrolling isn t possible   You may of course place another div  such as your modal  with a higher z-index than  Prevent in the markup  This allows you to create pop-up windows that don t suffer from scrolling issues   This solution is better because it doesn t hide the scrollbars  jumping affect   It doesn t require event listeners and it s easy to implement  It works in all browsers  although with IE7  amp  8 you have to play around  depends on your specific code     html   lt body gt     lt div id  YourModal  style  display none   gt  lt  div gt     lt div id  Prevent  style  display none   gt  lt  div gt     lt div id  WebsiteContainer  gt        lt div id  Website  gt       website goes here          lt  div gt     lt  div gt   lt  body gt    css  body   overflow  hidden      YourModal    z-index 200      modal styles here        Prevent    z-index 100   position absolute   left 0px   height 100    width 100    background transparent      WebsiteContainer     z-index 50    overflow auto    position  absolute    height 100     width 100      Website     position relative      jquery js  function PreventScroll A       switch  A        case  on       Prevent   show    break      case  off       Prevent   hide    break          disable enable the scroll  PreventScroll  on       prevent scrolling PreventScroll  off       allow scrolling
