滚动滚动滚动到元素不起作用时

Question

我想在滚动到包含它的元素时自动播放我的猫头鹰旋转器（v2）。由于某种原因，它一次滑动一次，然后在我使用鼠标输入时停止。

这是我要触发自动播放的HTML元素：

<div class="owl-carousel r-latest-news-list" id="r-latest-news-slider">

全部正确加载了

这是我在该元素上输入鼠标时触发自动播放的代码：

if($("#r-latest-news-slider").length > 0){
    var owl = $('#r-latest-news-slider').owlCarousel({
        loop:true,
        margin: 30,
        items: 4,
        nav: false,
        dots: true,
        responsive:{
            0:{
                items:2
            },
            600:
                items:2
            },
            1000:{
                items:4
            }
        }
    })
    $('#r-latest-news-slider').on("mouseenter", function(e) {
        console.log('mouse enter');
        owl.trigger('play.owl.autoplay', [2000]);
    })
}

嘿，这个问题在这里回答：https：//lazyfox.io/task/qp6/owl-carousel-autoplay-autoplay-when-scrollling-scrollling-to-lement-not-working/>

if($("#r-latest-news-slider").length > 0) {
    var owl = $('#r-latest-news-slider').owlCarousel({
        loop: true,
        margin: 30,
        items: 4,
        nav: false,
        dots: true,
        responsive: {
            0: {
                items:2
            },
            600: {
                items:2
            },
            1000: {
                items:4
            }
        }
    });
}
// Function for checking if the element is in view
function isScrolledIntoView(elem) {
    var docViewTop = $(window).scrollTop();
    var docViewBottom = docViewTop + $(window).height();
    var elemTop = $(elem).offset().top;
    var elemBottom = elemTop + $(elem).height();
    return ((elemBottom <= docViewBottom) && (elemTop >= docViewTop));
}
var animate = false;
// Function activated when scrolling
$(window).scroll(function() {
    // Check if the element is visible
    if(isScrolledIntoView("#r-latest-news-slider") && !animate) {
        owl.trigger('play.owl.autoplay', [1000]);
        animate = true;
        console.log('Starting animation');
    } else if(!isScrolledIntoView("#r-latest-news-slider") && animate) {
        owl.trigger('stop.owl.autoplay', [1000]);
        animate = false;
        console.log('Stopping animation');
    }
});
