cSlider: stop autoplay on mouseover

问题


How can I stop the autoplay function of cSlider with an onmouseover event?

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>

What I have tried so far with jQuery:

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

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

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

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

This is the one I'm using:

This feature not implemented by default but this shouldn't stop you from implementing it on your own. Look at modified plugin code below (draw attention on stop and 'start' methods)

(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');

            var $navigation = $('<nav class="da-dots"/>');
            for (var i = 0; i < this.slidesCount; ++i) {

                $navigation.append('<span/>');

            }
            $navigation.appendTo(this.$el);

            this.$pages = this.$el.find('nav.da-dots > span');
            this.$navNext = this.$el.find('span.da-arrows-next');
            this.$navPrev = this.$el.find('span.da-arrows-prev');

            this.isAnimating = false;

            this.bgpositer = 0;

            this.cssAnimations = Modernizr.cssanimations;
            this.cssTransitions = Modernizr.csstransitions;

            if (!this.cssAnimations || !this.cssAnimations) {

                this.$el.addClass('da-slider-fb');

            }

            this._updatePage();

            // load the events
            this._loadEvents();

            // slideshow
            if (this.options.autoplay) {

                this._startSlideshow();

            }

        },
        _navigate: function (page, dir) {

            var $current = this.$slides.eq(this.current), $next, _self = this;

            if (this.current === page || this.isAnimating) return false;

            this.isAnimating = true;

            // check dir
            var classTo, classFrom, d;

            if (!dir) {

                (page > this.current) ? d = 'next' : d = 'prev';

            }
            else {

            }

            if (this.cssAnimations && this.cssAnimations) {

    $.fn.cslider = function (options) {

            });

        }

        return this;

    };

})(jQuery);

With updated plugin you can pause and renew autiplaying with this code:

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