javascript - bug ScrollTop on Safari ipad -

i responsive website bootstrap anchor html in navigation. in nav bar have logo , when user click on , site scroll top. , works in desktop. in ipad safari when click logo scroll top , working once. , nav bar anchor bug after that.

how fix that?

my code :

$(document).ready(function(){ $('.brand').bind('click',function(){     $('html,body').animate({scrolltop: 0}, 'normal'); }); }); 

update

try "on" bind method

as of jquery 1.7+ better approach use "on" method not bind.

$(document).ready(function() { $(".brand").on("click", function ()  {    $('body').animate({scrolltop: 0}, 'normal'); alert('image clicked')  });  }); 

thanks ab
