我有一些代码：

$(window).load(function(){
	// Horizontal scroll
    if($(".js-page-scroll").length){
        $(".js-page-scroll").mCustomScrollbar({
        	axis:"x",
            theme:"dark-3",
            // scrollbarPosition: 'outside',
            advanced:{ autoExpandHorizontalScroll:true },

            callbacks:{
                    whileScrolling:function(){
                    	
                    	new WOW().init();
                        
                    }
                }
        });
    }
});
main {
    display: flex;
    flex-flow: row nowrap;
    align-items: center;
    align-content: center;
    justify-content: space-between;
}

section {
    display: block;
    width: 300px;
    border: 1px solid #000;
    padding: 1rem;
}

.js-page-scroll {
    width: 100%;
    overflow-x: auto;
}

我使用自定义滚动（水平）-malihu 自定义滚动条

对于动画 - animate.css 和wow.js

问题在于，水平滚动时，块中的文本平滑地出现（动画），因此是顺序的（就像使用 wow.js 时一样）。

问题：如何为水平滚动配置 wow.js（或者，也许是另一个插件）？or如何为自定义滚动配置 animate.css（当滚动块平滑地按顺序出现时）？

在您的代码段中，问题是您在滚动时启动了 WOW 插件。这就是为什么同时触发所有段落标签的动画的原因。

从您的代码段中，我添加了自定义代码而不是使用WOW 插件。 滚动时我调用了我添加的自定义函数animateContent();

JS代码

// Custome code for smooth animation 

                  function animateContent() {

                   var divWidth = $(".js-page-scroll").width();
                   var divWidthLg = $(".js-page-scroll").width() - 20;
                   var divWidthMd = $(".js-page-scroll").width() - 40;
                   var divWidthSm = $(".js-page-scroll").width() - 100;
                        //console.log(divWidth);
                         //console.log(divWidthLg);console.log(divWidthMd);


                    var section =$("section");


                     section.each(function(){


                     var offset = $(this).offset().left;
                     var ind = $(this).index() + 1;

                    // console.log(ind, offset);

                     if(offset > divWidth) {
                         $("p" , this).addClass("animated fadeOutUp");

                      }

                     if ( (offset < divWidthLg)){

                     if ($("p" , this).hasClass("fadeOutUp")){
                     $("p" , this).removeClass("fadeOutUp");
                     $("p" , this).addClass("animated fadeInUp");
                     setTimeout(function(){
                     $("p" , this).removeClass("fadeInUp");
                     }, 1500);
                     }
                     else {
                     $("p" , this).addClass("animated fadeInUp");
                     }

                     }

                     if(offset < divWidthSm) {
                      // $("p" , this).removeClass("fadeOutUp");
                       // $("p" , this).removeClass("fadeInUp");
                     }

                     });

                }

我做了什么：

  • 起初，我找到了外层的总宽度div
  • 然后在它旁边我找到了每个的偏移位置section
  • 如果偏移位置小于外部 div 的总宽度和正确的偏移位置，我添加了 animated fadeInUp类。

这是Fiddle 中的演示。

更新（每个元素的单独动画）

在这里，我附上了Fiddle 演示链接。

我在这里所做的： 我只是获得动画IN和OUT类表单data attribute，并在必要时附加所需的动画。

这样，您可以处理每个部分的IN和OUT动画。

$(window).ready(function(){
    	// Horizontal scroll
        if($(".js-page-scroll").length){
            $(".js-page-scroll").mCustomScrollbar({

                theme:"dark-3",
                // scrollbarPosition: 'outside',
                advanced:{ autoExpandHorizontalScroll:true },

                callbacks:{
                        whileScrolling:function(){
                     animateContent();
                        }
                    }
            });
        }
    });
                //	new WOW().init();
                
                function animateContent() {

水平滚动检测可以通过一些简单的 JS 实现，不需要额外的库。您正在使用 JQuery，因此这是使用它的一种可能的解决方案。

我使用了 Gemini 自定义 scollbar，因为它非常轻巧且用户友好。

我还包括了一个偏移量，因此您可以决定何时显示动画，而不是在元素出现后立即将其关闭。

在这里查看小提琴：http: //jsfiddle.net/zfd2t31h/1/

JS

// Add custom scrollbar
var myScrollbar = new GeminiScrollbar({
  element: document.querySelector('.js-page-scroll')
}).create();

// Add scroll events
var scrollContainer = $('.gm-scroll-view');
var scrollElem = $('section');
var offset = 300;

scrollContainer.scroll(function() {
  var $thisContainer = $(this);

  $thisContainer.find(scrollElem).each(function(n) {
    var $thisElem = $(this);

    if ($thisElem.position().left + $thisElem.width() > 0 && $thisElem.position().left < $thisContainer.width() - offset) {
      $('p', $thisElem).addClass('animated fadeInUp');
    }
  });
});
