To answer your main question     How do I simulate a hover with a touch in touch enabled browsers      Simply allow    clicking    the element  by tapping the screen   and then trigger the hover event using JavaScript   var p   document getElementsByTagName  p   0   p onclick   function         Trigger the  hover  event on the paragraph  p onhover call p        This should work  as long as there   s a hover event on your device  even though it normally isn   t used    Update  I just tested this technique on my iPhone and it seems to work fine  Try it out here  http   jsfiddle net mathias YS7ft show light   If you want to use a    long touch    to trigger hover instead  you can use the above code snippet as a starting point and have fun with timers and stuff

Use can use CSS too  add focus and active  for IE7 and under  to the hidden link  Example of a ul menu inside a div with class menu    menu ul ul  display none  position absolute  left 100   top 0  padding 0    menu ul ul ul  display none  position absolute  top 0  left 100     menu ul ul a   menu ul ul a focus   menu ul ul a active   width 170px  padding 4px 4   background  e77776  color  fff  margin-left -15px     menu ul li hover  gt  ul   display block     menu ul li ul li  margin 0     It s late and untested  should work  -

Add this code and then set class  tapHover  to elements which you would like to work this way  First time you tap an element it will gain pseudoclass   hover  and class  tapped   Click event will be prevented  Second time you tap the same element - click event will be fired    x000D   x000D     Activate only in devices with touch screen x000D  if  ontouchstart  in window  x000D    x000D         this will make touch event add hover pseudoclass x000D      document addEventListener  touchstart   function e      true   x000D   x000D         modify click event x000D      document addEventListener  click   function e    x000D             get  tapHover element under cursor x000D          var el   jQuery e target  hasClass  tapHover   x000D                jQuery e target  x000D                jQuery e target  closest   tapHover    x000D   x000D          if  el length  x000D              return  x000D   x000D             remove tapped class from old ones x000D          jQuery   tapHover tapped   each function     x000D              if this    el get 0   x000D                  jQuery this  removeClass  tapped    x000D              x000D   x000D          if  el hasClass  tapped    x000D            x000D                 this is the first tap x000D              el addClass  tapped    x000D              e preventDefault    x000D              return false  x000D            x000D          else x000D            x000D                 second tap x000D              return true  x000D            x000D         true   x000D    x000D   box   x000D   float   left  x000D    x000D   display  inline-block  x000D   margin   50px 0 0 50px  x000D   width   100px  x000D   height   100px  x000D   overflow  hidden  x000D    x000D   font-size  20px  x000D    x000D   border   solid 1px black  x000D    x000D   box tapHover   x000D   background  yellow  x000D    x000D   box tapped   x000D   border   solid 3px red  x000D    x000D   box hover   x000D   background  red  x000D    x000D   lt div class  box  onclick  this innerHTML   Math random   toFixed 5   gt  lt  div gt  x000D   lt div class  box tapHover  onclick  this innerHTML   Math random   toFixed 5   gt  lt  div gt  x000D   lt div class  box tapHover  onclick  this innerHTML   Math random   toFixed 5   gt  lt  div gt  x000D   x000D   x000D

OK  I ve worked it out  It involves changing the CSS slightly and adding some JS   Using jQuery to make it easy     document  ready function             hover   on  touchstart touchend   function e            e preventDefault              this  toggleClass  hover effect                  In english  when you start or end a touch  turn the class hover effect on or off   Then  in your HTML  add a class hover to anything you want this to work with  In your CSS  replace any instance of   element hover       rule properties      with  element hover  element hover effect       rule properties      And just for added usefulness  add this to your CSS as well    hover   -webkit-user-select  none  -webkit-touch-callout  none              To stop the browser asking you to copy save select the image or whatever   Easy

Without device  or rather browser  specific JS I m pretty sure you re out of luck   Edit  thought you wanted to avoid that until i reread your question  In case of Mobile Safari you can register to get all touch events similar to what you can do with native UIView-s  Can t find the documentation right now  will try to though

Solved 2019 - Hover on Touch  It now seems best to avoid using hover altogether with ios or touch in general  The below code applies your css as long as touch is maintained  and without other ios flyouts  Do this    Jquery add     p   on  touchstart   function e      this  focus    e preventDefault        CSS  replace p hover with p focus  and add p active    Options    replace jquery p selector with any class etc to have the effect remain  keep p hover as well  and add body cursor ponter   so a tap anywhere ends it try click  amp  mouseover events as well as touchstart in same code  but not tested  remove e preventDefault    to enable users to utilise ios flyouts eg copy   Notes    only tested for text elements  ios may treat inputs etc differently only tested on iphone XR ios 12 1 12  and ipad 3 ios 9 3 5  using Safari or Chrome

A mix of native Javascript and jQuery   var gFireEvent   function  oElem sEvent      try    if  typeof sEvent     string   amp  amp  o isDOM  oElem         var b      document createEvent        evt   b document createEvent  HTMLEvents   document createEventObject      if  b            evt initEvent sEvent  true  true         return  oElem dispatchEvent evt         return oElem fireEvent  on  sEvent evt         catch e      return false          Next you can do is  bIsMob etc you have to determine yourself       if   lt  lt  lt  bIsMob    bIsTab    bisTouch  gt  gt  gt                document  on  mousedown   function e                gFireEvent e target  mouseover             on  mouseup   function e                gFireEvent e target  mouseout

One way to do it would be to do the hover effect when the touch starts  then remove the hover effect when the touch moves or ends   This is what Apple has to say about touch handling in general  since you mention iPhone

User · Answer

All you need to do is bind touchstart on a parent  Something like this will work      body   on  touchstart   function          You don t need to do anything in the function  leave it empty  This will be enough to get hovers on touch  so a touch behaves more like  hover and less like  active  iOS magic

Further Improved Solution  First I went with the Rich Bradshaw s approach  but then problems started to appear  By doing the e preventDefault   on  touchstart  event  the page no longer scrolls and  neither the long press is able to fire the options menu nor double click zoom is able to finish executing    A solution could be finding out which event is being called and just e preventDefault   in the later one   touchend   Since scroll s  touchmove  comes before  touchend  it stays as by default  and  click  is also prevented since it comes afterwords in the event chain applied to mobile  like so      Binding to the   static parent  ensuring dynamic ajaxified content     static parent   on  touchstart touchend     link   function  e            If event is  touchend  then        if  e type     touchend                Ensuring we event prevent default in all major browsers         e preventDefault   e preventDefault     e returnValue   false                Add class responsible for  hover effect       this  toggleClass  hover effect          But then  when options menu appears  it no longer fires  touchend  responsible for toggling off the class  and next time the hover behavior will be the other way around  totally mixed up    A solution then would be  again  conditionally finding out which event we re in  or just doing separate ones  and use addClass   and removeClass   respectively on  touchstart  and  touchend   ensuring it always starts and ends by respectively adding and removing instead of conditionally deciding on it  To finish we will also bind the removing callback to the  focusout  event type  staying responsible for clearing any link s hover class that might stay on and never revisited again  like so       static parent   on  touchstart     link   function  e          this  addClass  hover effect             static parent   on  touchend focusout     link   function  e           Think double click zoom still fails here     e preventDefault   e preventDefault     e returnValue   false        this  removeClass  hover effect          Atention  Some bugs still occur in the two previous solutions and  also think  not tested   double click zoom still fails too   Tidy and Hopefully Bug Free  not     Javascript Solution  Now  for a second  cleaner  tidier and responsive  approach just using javascript  no mix between  hover class and pseudo  hover  and from where you could call directly your ajax behavior on the universal  mobile and desktop   click  event  I ve found a pretty well answered question from which I finally understood how I could mix touch and mouse events together without several event callbacks inevitably changing each other s ones up the event chain  Here s how       static parent   on  touchstart mouseenter     link   function  e          this  addClass  hover effect             static parent   on  mouseleave touchmove click     link   function  e          this  removeClass  hover effect            As it s the chain s last event we only prevent it from making HTTP request     if  e type     click             e preventDefault   e preventDefault     e returnValue   false              Ajax behavior here

My personal taste is to attribute the  hover styles to the  focus state as well  like   p       color  red     p hover  p focus       color  blue      Then with the following HTML    lt p id  some-p-tag  tabindex  -1  gt WOOOO lt  p gt    And the following JavaScript       some-p-tag   on  touchstart   function e       e preventDefault        var  elem     this        if  elem is   focus                this can be registered as a  click  on a mobile device  as it s a double tap          elem blur             else            elem focus

Try this    lt script gt  document addEventListener  touchstart   function      true    lt  script gt    And in your CSS   element hover  element active   -webkit-tap-highlight-color  rgba 0 0 0 0   -webkit-user-select  none  -webkit-touch-callout  none   only to disable context menu on long press       With this code you don t need an extra  hover class
