滚动时的Jquery延迟

Question

嗨我有一组图标，我想在向下滚动时逐一显示。

我使用http://www.justinaguilar.com/animations/作为动画。

如何在我的jquery上添加延迟功能，以便逐个显示？ 任何可以替代这种效果的插件？

有什么建议吗？

谢谢你们

{
  visibility:hidden;
}

$(window).scroll(function () {
    $('#kinect-logo').each(function () {
        var imagePos = $(this).offset().top;
        var topOfWindow = $(window).scrollTop();
        if (imagePos < topOfWindow + 400) {
            $(this).addClass("slideUp");

Answer 1

您可以使用javascript函数setTimeOut（）

添加延迟

setTimeout(function (){
// Code you want to delay or you can call the function reference directly instead of defining one
}, 2000);

Answer 2

尝试这样的事情

$(window).scroll(function () {
    $('#kinect-logo,#create,#define,#sync,#cloud,#scale').each(function (index,element) {
        var imagePos = $(this).offset().top;
        var topOfWindow = $(window).scrollTop();
        if (imagePos < topOfWindow + 400) {
            $(this).delay(index*600).queue(function(){
                $(this).addClass("slideUp").dequeue();
            });
        }
    });

});
