Question

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，使用以下选项定义：

 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: [
            "&lsaquo;",
            "&rsaquo;"
        ]
    },

...

当用户点击导航箭头时，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，还没有渲染.owl-nav元素。它不是很优雅，但它可以达到目的）。

问题是当我点击导航箭头时，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。

非常感谢任何关于如何解决这个问题的提示。谢谢！

Answer 1

从我收集的here和here来看，它似乎是一个计时器问题：触发stop.owl.autoplay会破坏计时器，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）。

你可以尝试：

$('.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');
});

Answer 2

为了停止猫头鹰自动播放，您可以触发相应的事件：

stop.owl.autoplay：停止自动播放。

，同时：

play.owl.autoplay：运行自动播放

摘录：

＆＃13;

$('.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: [
        "&lsaquo;",
        "&rsaquo;"
    ]
});
$('#btn1').on('click', function(e) {
    $('.owl-carousel').trigger('stop.owl.autoplay');
})
$('#btn2').on('click', function(e) {
    $('.owl-carousel').trigger('play.owl.autoplay');
})
