jquery - Image switch with data-attribute - 


$(window).scroll(function() {         var scroll = $(window).scrolltop();     if (scroll >= 50) {         $("header").addclass("sticky");         $('header .logo img').attr('src', $('header .logo img').data("hover"));     } else {         $("header").removeclass("sticky");         $("header").addclass("");         $('header .logo img').attr('src', $('header .logo img').data("src"));     } });

the first 1 works src not coming anymore. how should done?

<img src="img/logo2.png" data-hover="img/logo.png" alt="" class="img-responsive" />

you should add data-src attribute try access.

<img src="img/logo2.png" data-src="img/logo2.png" data-hover="img/logo.png" alt="" class="img-responsive" />
