带有其他JavaScript的jQuery插件干扰

Question

所以我正在使用一个创建垂直分页动画的插件。

它基本上是制作一个全屏框，并在此框内移动“部分”。

这是帮助显示我的意思的html。

<div id="fullpage">
    <div class="section"></div>
    <div class="section"></div>
    <div class="section"></div>
</div>

当您向下滚动时，我有一个简单的javascript函数可隐藏导航。 问题是，有了这个新插件，您实际上并没有向下滚动。 部分仅在固定的盒子内移动。

这是我用于导航的javascript函数。

$(window).scroll(function (event) {
    var y = $(this).scrollTop();

    if (y > 0) {

        $('#navBar').addClass('scroll');
    } 
    else{

        $('#navBar').removeClass('scroll');
    }
});

因此y > 0不会再与此插件一起触发，因此导航不会正确隐藏。

我认为必须有一种方法可以稍微更改一下此简单的代码并使它工作。 也许通过在部分内部使用ID？

这是我的html与所应用插件的一般结构的外观。

您可以使用onLeave事件获取滚动索引值并切换类scroll 。

$('#fullpage').fullpage({
        onLeave: function (anchorLink, index, slideIndex, direction) {
            //console.log(index);
            if (index > 1) {
                $('#navBar').addClass('scroll');
            } else {
                $('#navBar').removeClass('scroll');

            }
        }
    });
