javascript - Prevent hyperlink on touch and show hover state -


i'm not sure why when touch link on on site i'm building on iphone/tablet doesn't trigger hover on state , instead jumps straight through link. can see test site here http://lovelldesign.co.uk/home

the links big images , hover on state reveals name of project, that's why it's essential hover on state triggered first touch , user need touch again go through project.

i've searched touchstart examples on here , tried work them solve own problem no avail.

here html

<div class="projectcontainer">     <a href="<perch:content id="url" label="url" required="true" />" class="projectoverlay">         <h1><perch:content id="title" type="text" label="heading" required="true" /></h1>     </a>      <img src="<perch:content id="image" type="image" label="image" />" />

here css:

.projectcontainer {     position: relative;     max-width: 100%;     overflow: hidden;     margin-bottom: 7px;     height: 100%;     display: block; }  .projectcontainer:hover .projectoverlay {     opacity: 0.9;     -moz-transition: 0.3s ease-out;     -webkit-transition: 0.3s ease-out;     -o-transition: 0.3s ease-out;     transition: 0.3s ease-out; }  .projectcontainer .projectoverlay {     opacity: 0;     background-color: #00152e;     position: absolute;     top: 0px;     left: 0px;     width: 96%;     height: 100%;     padding: 2%;     color: white;     text-decoration: none; }

any appreciated.

many thanks

i had same "issue" (actually it's correct behaviour) sometimes. fix it, need little of javascript.

first of all, let's detect touch events. can modernizr, minimum bundle achieve it: http://modernizr.com/download/#-touch-cssclasses-teststyles-prefixes

1) include generated script in <head> section: modernizr going add "touch" class page's <html> element if touch events supported, "no-touch" class if they're not.

2) if "touch" events enabled, need add javascript listener simulate hover state @ first click:

if(modernizr.touch){      var hoverclass = 'projectcontainer-hover', // "simulated hover" class         $projectcontainers = $('.projectcontainer');      $projectcontainers.on('click',function(event){         var $this = $(this);         if(!$this.hasclass(hoverclass)){             event.preventdefault();             $projectcontainers.removeclass(hoverclass);             $this.addclass(hoverclass);             return false;         }     }).on('focusout',function(){         // remove class if user focuses on element         $(this).removeclass(hoverclass);       }); }

i'm supposing you're using jquery. if you're not, , need support older ies, should know selecting elements class is not easy.

3) @ last, change css selector way:

.projectcontainer:hover .projectoverlay, .projectcontainer-hover .projectoverlay {     // ...etc...     }

note: method isn't perfect @ all, because touch events enabled in many laptops nowadays. device touch events enabled need double click if implement it. it's decide if it's worth it!

atm think alternative user-agent spoofing, really want avoid.
