You can use is   visible    in jquery And for     item hover   it is working in Jquery also   this is a htm code snnipet          lt li class  item-109 deeper parent  gt   lt a class  root  href   Comsopolis index php matiers  gt  lt span gt Matiers lt  span gt  lt  a gt   lt ul gt   lt li class  item-110 noAff  gt   lt a class   item sousMenu  href   Comsopolis index php matiers tsdi  gt   lt span gt Tsdi lt  span gt   lt  a gt   lt  li gt   lt li class  item-111 noAff  gt   lt a class  item  href   Comsopolis index php matiers reseaux  gt   lt span gt R  seaux lt  span gt   lt  a gt   lt  li gt   lt  ul gt   lt  li gt    and this is the JS Code        menutop  gt  li   hover function        menutop li ul        this  find  ul   show  fast       function         if   this  find  ul   is   hover          this  hide  fast               root   ul   mouseleave function         if   this  is   visible          this  hide  fast           this what i was talking about

You can test with jQuery if any child div has a certain class  Then by applying that class when you mouse over and out out a certain div  you can test whether your mouse is over it  even when you mouse over a different element on the page  Much less code this way   I used this because I had spaces between divs in a pop-up  and I only wanted to close the pop up when I moved off of the pop up  not when I was moving my mouse over the spaces in the pop up   So I called a mouseover function on the content div  which the pop up was over   but it would only trigger the close function when I moused-over the content div  AND was outside the pop up         pop-up   mouseover function e              this  addClass  over                 pop-up   mouseout function e              this  removeClass  over                  mainContent   mouseover function e               if       expanded   hasClass  over                  Drupal dhtmlMenu toggleMenu     expanded

This code illustrates what happytime harry and I are trying to say  When the mouse enters  a tooltip comes out  when the mouse leaves it sets a delay for it to disappear  If the mouse enters the same element before the delay is triggered  then we destroy the trigger before it goes off using the data we stored before      someelement   mouseenter function        clearTimeout   this  data  timeoutId           this  find   tooltip   fadeIn  slow       mouseleave function        var someElement     this           timeoutId   setTimeout function                someElement find   tooltip   fadeOut  slow               650         set the timeoutId  allowing us to clear this trigger if the mouse comes back over     someElement data  timeoutId   timeoutId

I see timeouts used for this a lot  but in the context of an event  can t you look at coordinates  like this    function areXYInside e             var w e target offsetWidth          var h e target offsetHeight          var x e offsetX          var y e offsetY          return   x lt 0    x gt  w    y lt 0    y gt  h       Depending on context  you may need to make sure  this  e target  before calling areXYInside e    fyi- I m looking at using this approach inside a dragLeave handler  in order to confirm that the dragLeave event wasn t triggered by going into a child element   If you don t somehow check that you re still inside the parent element  you might mistakenly take action that s meant only for when you truly leave the parent   EDIT  this is a nice idea  but does not work consistently enough   Perhaps with some small tweaks

I have answered this in another question  with all details you may need   Detect IF hovering over element with jQuery  has 99 upvotes at the time of writing   Basically  you can do something like   var ishovered   oi is   hover      This works only if oi is a jQuery object containing a single element  If there are multiple elements matched  you need to apply to each element  for example   var hoveredItem        ol gt li   filter function     return   this  is   hover                             not  filter   hover    as we can t apply  hover on multiple elements   This was tested starting jQuery 1 7

Here is a function which helps you check if the mouse is inside an element or not  The only thing you should do is to call the function where you can have a live mouse-associated EventObject  something like this      body   mousemove function event        element mouse is inside     mycontainer   event  true             You can see the source code here in github or at the bottom of the post   https   github com mostafatalebi ElementsLocator blob master elements locator jquery js  function element mouse is inside   elementToBeChecked  mouseEvent  with margin  offset object        if  with margin                with margin   false            if typeof offset object      object                 offset object                 var elm offset   elementToBeChecked offset        var element width   elementToBeChecked width        element width    parseInt elementToBeChecked css  padding-left   replace  px             element width    parseInt elementToBeChecked css  padding-right   replace  px             var element height   elementToBeChecked height        element height    parseInt elementToBeChecked css  padding-top   replace  px             element height    parseInt elementToBeChecked css  padding-bottom   replace  px             if  with margin                element width    parseInt elementToBeChecked css  margin-left   replace  px                 element width    parseInt elementToBeChecked css  margin-right   replace  px                 element height    parseInt elementToBeChecked css  margin-top   replace  px                 element height    parseInt elementToBeChecked css  margin-bottom   replace  px                    elm offset rightBorder   elm offset left element width      elm offset bottomBorder   elm offset top element height       if offset object hasOwnProperty  top                  elm offset top    parseInt offset object top             if offset object hasOwnProperty  left                  elm offset left    parseInt offset object left             if offset object hasOwnProperty  bottom                  elm offset bottomBorder    parseInt offset object bottom             if offset object hasOwnProperty  right                  elm offset rightBorder    parseInt offset object right             var mouseX   mouseEvent pageX      var mouseY   mouseEvent pageY       if    mouseX  gt  elm offset left  amp  amp  mouseX  lt  elm offset rightBorder           amp  amp   mouseY  gt  elm offset top  amp  amp  mouseY  lt  elm offset bottomBorder                  return true            else               return false

Thanks to both of you   At some point I had to give up on trying to detect if the mouse was still over the element   I know it s possible  but may require too much code to accomplish     It took me a little while but I took both of your suggestions and came up with something that would work for me   Here s a simplified  but functional  example       HoverHelp    hover       function              var HelpID           this  attr  HoverHelp              HelpID  css  top     this  position   top   25             HelpID  css  left     this  position   left             HelpID  attr  fadeout    false              HelpID  fadeIn               function              var HelpID           this  attr  HoverHelp              HelpID  attr  fadeout    true            setTimeout function     if    HelpID  attr  fadeout       true     HelpID  fadeOut       100              And then to make this work on some text this is all I have to do    lt div id  tip TextHelp  style  display  none   gt This help text will show up on a mouseover  and fade away 100 milliseconds after a mouseout  lt  div gt   This is a  lt span class  Help  HoverHelp  tip TextHelp  gt mouse over lt  span gt  effect    Along with a lot of fancy CSS  this allows some very nice mouseover help tooltips   By the way  I needed the delay in the mouseout because of tiny gaps between checkboxes and text that was causing the help to flash as you move the mouse across   But this works like a charm   I also did something similar for the focus blur events

I couldn t use any of the suggestions above  Why I prefer my solution  This method checks if mouse is over an element at any time chosen by You  Mouseenter and  hover are cool  but mouseenter triggers only if you move the mouse  not when element moves under the mouse   hover is pretty sweet but     IE  So I do this   No 1  store mouse x  y position every time it s moved when you need to  No 2  check if mouse is over any of elements that match the query do stuff     like trigger a mouseenter event     define mouse x  y variables so they are traced all the time var mx   0      mouse X position var my   0      mouse Y position     update mouse x  y coordinates every time user moves the mouse   document  mousemove function e       mx   e pageX      my   e pageY          check is mouse is over an element at any time You need  wrap it in function if You need to      my element   each function        boxX     this  offset   left      boxY     this  offset   top      boxW     this  innerWidth        boxH     this  innerHeight        if   boxX  lt   mx   amp  amp           boxX   1000  gt   mx   amp  amp           boxY  lt   my   amp  amp           boxY   boxH  gt   my                    mouse is over it so you can for example trigger a mouseenter event           this  trigger  mouseenter

I needed something exactly as this  in a little more complex environment and the solution with a lot of  mouseenters  and  mouseleaves  wasnt working properly  so i created a little jquery plugin that adds the method ismouseover  It has worked pretty well so far     jQuery ismouseover  method  function            mlp    x 0 y 0      Mouse Last Position     function documentHandler            var  current   this     document     this      this  contents             current mousemove function e  jQuery mlp    x e pageX y e pageY              current find  iframe   load documentHandler               documentHandler         fn ismouseover   function overThis              var result   false          this eq 0  each function                       var  current     this  is  iframe       this  contents   find  body       this                   var offset    current offset                                 result      offset left lt    mlp x  amp  amp  offset left    current outerWidth    gt    mlp x  amp  amp                              offset top lt    mlp y  amp  amp  offset top    current outerHeight    gt    mlp y                        return result              jQuery     Then in any place of the document yo call it like this and it returns true or false       player   ismouseover     I tested it on IE7   Chrome 1  and Firefox 4 and is working properly

JUST FYI for future finders of this    I made a jQuery plugin that can do this and a lot more   In my plugin  to get all elements the cursor is currently hovered over  simply do the following     cursor  isHover       will return jQ object of all elements the cursor is                          currently over  amp  doesn t require timer   As I mentioned  it also has alot of other uses as you can see in the jsFiddle found here

Set a timeout on the mouseout to fadeout and store the return value to data in the object  Then onmouseover  cancel the timeout if there is a value in the data   Remove the data on callback of the fadeout   It is actually less expensive to use mouseenter mouseleave because they do not fire for the menu when children mouseover mouseout fire

In jQuery you can use  is   hover    so  function IsMouseOver oi       return   oi  is   hover        would now be the most concise way to provide the function requested in the OP   Note  The above does not work in IE8 or lower  As less succinct alternative that does work in IE8  if I can trust IE9 s IE8 modus   and does so without triggering        hover      all over the place  nor requires knowing a selector for the element  in which case Ivo s answer is easier    function IsMouseOver oi        return oi length  amp  amp              oi parent                 find   hover                 filter function s  return oi 0   this                 length  gt  0

Extending on what  Happytime harry  said  be sure to use the  data   jquery function to store the timeout id  This is so that you can retrieve the timeout id very easily when the  mouseenter  is triggered on that same element later  allowing you to eliminate the trigger for your tooltip to disappear

As I cannot comment  so I will write this as an answer    Please understand the difference between css selector   hover  and the hover event     hover  is a css selector and was indeed removed with the event when used like this     elementId   is   hover    but in it s meaning it has really nothing to do with the jQuery event hover    if you code     elementId hover    the element will only be selected when you hover with the mouse  the above statement will work with all jQuery versions as your selecting this element with pure and legit css selection   On the other hand the event hover which is       elementId   hover       function               doSomething                  is indeed deprecaded as jQuery 1 8 here the state from jQuery website      When the event name  hover  is used  the event subsystem converts it   to  mouseenter mouseleave  in the event string  This is annoying for   several reasons       Semantics  Hovering is not the same as the mouse entering and leaving   an element  it implies some amount of deceleration or delay before   firing  Event name  The event type returned by the attached handler is   not hover  but either mouseenter or mouseleave  No other event does   this  Co-opting the  hover  name  It is not possible to attach an   event with the name  hover  and fire it using  trigger  hover    The   docs already call this name  strongly discouraged for new code   I d   like to deprecate it officially for 1 8 and eventually remove it    Why they removed the usage is   hover   is unclear but oh well  you can still use it like above and here is a little hack to still use it    function                      hover selector was removed from jQuery 1 8  and cannot be used with  is   hover          but using it in this way it works as  hover is css selector                       fn isMouseOver   function             return   this  parent   find   this  selector     hover   length  gt  0            jQuery     Oh and I would not recomment the timeout version as this brings a lot of complexity  use timeout functionalities for this kind of stuff if there is no other way and believe me  in 95  percent of all cases there is another way   Hope I could help a couple people out there   Greetz Andy

Just a note about the popular and helpful Arthur Goldsmith answer above  If you re moving your mouse from one element to another in IE  at least until IE 9  you may have some trouble getting this to work correctly if the new element has a transparent background  which it would by default   My workaround was the give the new element a transparent background image
