如何在单击导航箭头时停止猫头鹰轮播

我有一个简单的猫头鹰旋转木马,带有自动播放设置和导航箭头,定义如下:

var options = {
    mainBanner: {
        animateOut: 'fadeOut',
        autoplay: true,
        autoplayHoverPause: false,
        autoplaySpeed: 1200,
        dots: false,
        lazyLoad: true,
        loop: true,
        mouseDrag: false,
        pullDrag: false,
        touchDrag: false,
        nav: true,
        navText: [
            "‹",
            "›"
        ]
    },

...

当用户单击导航箭头时,我希望它停止自动播放 . 为此,我添加了以下功能:

setTimeout(function () {    
    $('.owl-nav > div').on('click', function () {
        $('.owl-carousel').trigger('stop.owl.autoplay');            
    })
}, 500);

(我添加了超时,因为加载此函数时,还没有呈现.owl-nav元素 . 它不是很优雅,但它可以达到目的) .

问题是当我单击导航箭头时,自动播放停止 . 但是,如果我再次点击它们(又一次又一次),滑块会保持自动播放 . 这不是预期的行为 - 我只是希望它从第一次点击停止 .

任何关于如何解决这个问题的提示都非常感谢 . 谢谢!

从我收集的herehere看来它是一个计时器问题:触发 stop.owl.autoplay 将破坏计时器,但不会更改自动播放设置,因此再次设置计时器 . 您必须在设置中关闭(如果要重新激活,则重新启动) .

你可以试试:

$('.owl-nav > div').on('click', function () {
    $('.owl-carousel').trigger('stop.owl.autoplay');

    //simple one (EDIT: not enough to make it work after testing it):
    //$('.owl-carousel').trigger('changeOption.owl.carousel', { autoplay: false });

    //or more complicated (will work for one carousel only, or else use 'each'):
    //EDIT: this one seems to work
    var carousel = $('.owl-carousel').data('owl.carousel');
    carousel.settings.autoplay = false; //don't know if both are necessary
    carousel.options.autoplay = false;
    $('.owl-carousel').trigger('refresh.owl.carousel');
});

为了阻止猫头鹰自动播放你可以触发相应的事件:

stop.owl.autoplay:停止自动播放 .

而:

play.owl.autoplay:运行自动播放

片段:

$('.owl-carousel').owlCarousel({
    animateOut: 'fadeOut',
    autoplay: true,
    autoplayHoverPause: false,
    autoplaySpeed: 10,
    dots: false,
    lazyLoad: true,
    loop: true,
    mouseDrag: false,
    pullDrag: false,
    touchDrag: false,
    nav: true,
    navText: [
        "‹",
        "›"
    ]
});
$('#btn1').on('click', function(e) {
    $('.owl-carousel').trigger('stop.owl.autoplay');
})
$('#btn2').on('click', function(e) {
    $('.owl-carousel').trigger('play.owl.autoplay');
})
