Add class when scroll down with AlloyUI
问题 I need to add a class when the user scroll down. I usually do this with jQuery : $(window).scroll(function() { var scroll = $(window).scrollTop(); if (scroll >= 10) { $(".dockbar").addClass("dockbar-opacity"); } }); How can I do the same thing with AlloyUI ? Really thanks. 回答1: Using the ScrollInfo plugin and its scroll event var body = Y.one('body'); body.plug(Y.Plugin.ScrollInfo); body.scrollInfo.on('scroll', function (e) { if (e.scrollTop >= 10){ Y.one('.dockbar').addClass('dockbar-opacity
