在同一类 JQUERY 的不同时间触发事件
Trigger an event on different time of the same class JQUERY
请在标题中建议编辑，因为我无法理解我应该给它起什么名字。
这是 HTML：

如您所见，这些东西属于同一类，但我必须以不同的方式命名它们，这样触发器就不会为同一类的每个元素触发，所以我将它们命名为 jstransitionportfolio[1-16]。但它大大增加了我的脚本时间。我想将它们组合在单个函数中，这样它就可以减少我的脚本时间，而且我不会有很多类，我的代码会更干净、更好。请帮忙！
你的代码可以简化：
$(window).scroll(function() {
var xScroll = $(this).scrollTop();
$(".some-class").each(function() {
var that = this;
if(xScroll > $(that).offset().top - ($(window).height() / 1.2)) {
setTimeout(function(){
$(that).addClass('some-other-class');
},150);
}
});
});
您只需要将.some-class和some-other-class更改为您选择的某个类名。
旁注：在向onScroll监听器添加内容时请小心，因为它会减慢滚动速度来降低用户体验。
在使用此功能之前，请从我们的服务项和 jstransitionportfolio 类中删除数字。您可以在此处查看演示
var setHeight=$(window).height() / 1.2;
var ourServices=$('.our-services-item');
var tranPortfolio=$('.jstransitionportfolio');
$(window).on('scroll',function(){
var xScroll = $(this).scrollTop();
ourServices.each(function(){
var el=$(this);
if(xScroll>(el.offset().top-setHeight))
setTimeout(function(){el.addClass('is-showing-our-services')},150);
});
tranPortfolio.each(function(){
var el=$(this);
if(xScroll>(el.offset().top-setHeight))
setTimeout(function(){el.addClass('is-showing-jstransitionportfolio')},150);
});
});
