问题描述
如何使用onmouseover事件停止cSlider的自动播放功能？
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>
到目前为止我用jQuery尝试了什么：
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
});
这是我正在使用的那个：
This is the one I'm using:
推荐答案
此功能默认情况下未实现，但这不应该阻止您自己实现它。查看下面的修改后的插件代码（引起注意停止和'开始'方法）
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"/>');

var instance = $.data(this, 'cslider');
if (!instance) {
$.data(this, 'cslider', new $.Slider(options, this));
}
});
}

};
})(jQuery);
使用更新的插件，您可以使用以下代码暂停和续订autiplaying：
With updated plugin you can pause and renew autiplaying with this code:
$('#da-slider').hover(
function () {
$(this).cslider("stop");
},
function () {
$(this).cslider("start");
}
);
