如何通过 onmouseover 事件停止 cSlider 的自动播放功能？

HTML:

<div id="da-slider" class="da-slider">

   <div class="da-slide">
     <p>Text</p>
   </div>

   <div class="da-slide">
     <p>More text</p>
   </div>

</div>

到目前为止，我对 jQuery 的尝试:

$(function() {
    $('#da-slider').cslider({
            autoplay    : true,
            bgincrement : 450
    });
});

$('#da-slider').hover(function() {

    if($('#daslider').autoplay('true')){
        autoplay: false
    }

}, function () {
    autoplay: true
});

这是我正在使用的:

最佳答案

默认情况下未实现此功能，但这不应该阻止您自己实现它。查看下面修改后的插件代码(注意 stop 和 'start' 方法)

(function ($, undefined) {

    /*
    * Slider object.
    */
    $.Slider = function (options, element) {

        this.$el = $(element);

        this._init(options);

    };

    $.Slider.defaults = {
        current: 0,     // index of current slide
        bgincrement: 50, // increment the bg position (parallax effect) when sliding
        autoplay: false, // slideshow on / off
        interval: 4000  // time between transitions
    };

    $.Slider.prototype = {
        _init: function (options) {

            this.options = $.extend(true, {}, $.Slider.defaults, options);

            this.$slides = this.$el.children('div.da-slide');
            this.slidesCount = this.$slides.length;

            this.current = this.options.current;

            if (this.current < 0 || this.current >= this.slidesCount) {

                this.current = 0;

            }

            this.$slides.eq(this.current).addClass('da-slide-current');

        }

        return this;

    };

})(jQuery);

使用更新的插件，您可以使用以下代码暂停和更新自动播放:

$('#da-slider').hover(
    function () {
        $(this).cslider("stop");
    },
    function () {
        $(this).cslider("start");
    }
);
