我看到这个小提琴样本
here
我想要当“到顶部”出现时,点击！应该滚动到顶部平滑或缓慢
$(window).scroll(function() {
if ($(this).scrollTop()) {
$('#toTop').fadeIn();
} else {
$('#toTop').fadeOut();
}
});
解决方法
$("#toTop").click(function () {
//1 second of animation time
//html works for FFX but not Chrome
//body works for Chrome but not FFX
//This strange selector seems to work universally
$("html,body").animate({scrollTop: 0},1000);
});
