Without external variables              element   bind  mousewheel   function e  d                if  this scrollTop      this scrollHeight - this offsetHeight   amp  amp  d  lt  0                      this scrollTop     0  amp  amp  d  gt  0                     e preventDefault

Plenty of good ideas on this thread   I have a lot of popups in my page for handling user input   What I use  is a combination of disabling the mousewheel and hiding the scrollbar   this disableScrollFn  function e         e preventDefault    e stopPropagation       document body style overflow    hidden      body   on  mousewheel   this disableScrollFn     Advantage of this is we stop the user from scrolling in any possible way  and without having to change css position and top properties   I m not concerened about touch events  since touch outside would close the popup   To disable this  upon closing the popup I do the following   document body style overflow    auto      body   off  mousewheel   this disableScrollFn     Note  I store a reference to my disableScrollFn on the existing object  in my case a PopupViewModel   for that gets triggered upon closing the popup to have access to disableScrollFn

Following Glens idea  here it goes another possibility  It would allow you to scroll inside the div  but would prevent the body to scroll with it  when the div scroll ends  However  it seems to accumulate too many preventDefault if you scroll too much  and then it creates a lag if you want to scroll up  Does anybody have a suggestion to fix that           scrollInsideThisDiv   bind  mouseover  function           var bodyTop   document body scrollTop            body   on               mousewheel   function e               if  document body scrollTop    bodyTop  return             e preventDefault               e stopPropagation                                            scrollInsideThisDiv   bind  mouseleave  function                 body   unbind  mousewheel

If you want to scroll the element you re over and prevent the window to scroll  here s a really useful function        Scrollable   on  DOMMouseScroll mousewheel   function ev        var  this     this           scrollTop   this scrollTop          scrollHeight   this scrollHeight          height    this height            delta    ev type     DOMMouseScroll                ev originalEvent detail   -40               ev originalEvent wheelDelta           up   delta  gt  0       var prevent   function             ev stopPropagation            ev preventDefault            ev returnValue   false          return false             if   up  amp  amp  -delta  gt  scrollHeight - height - scrollTop               Scrolling down  but this will take us past the bottom           this scrollTop scrollHeight            return prevent          else if  up  amp  amp  delta  gt  scrollTop               Scrolling up  but this will take us past the top           this scrollTop 0           return prevent                Apply the class  Scrollable  to your element and that s it

tfe answered this question in another post on StackOverflow  Answered  Another method would be to use     document  bind  touchmove  function event     event preventDefault          But it may prevent some of the jquery mobile functionality from working properly
