如何创建幻灯片的数组，然后只随机显示一定数量的人？
例如，如果我建立一个这样的数组：
var slides = [];
slides[0] = '<div class="item"><img alt="" src="/Slides/gallery.jpg"></div>';
slides[1] = '<div class="item"><img alt="" src="/Slides/item1.jpg"></div>';
slides[2] = '<div class="item"><img alt="" src="/Slides/forums.jpg"></div>';
slides[3] = '<div class="item"><img alt="" src="/Slides/featured.jpg"></div>';
slides[4] = '<div class="item"><img alt="" src="/Slides/sale.jpg"></div>';
slides[5] = '<div class="item"><img alt="" src="/Slides/discount.jpg"></div>';
slides[6] = '<div class="item"><img alt="" src="/Slides/gallery.jpg"></div>';
slides[7] = '<div class="item"><img alt="" src="/Slides/a.jpg"></div>';
slides[8] = '<div class="item"><img alt="" src="/Slides/b.jpg"></div>';
slides[9] = '<div class="item"><img alt="" src="/Slides/c.jpg"></div>';
slides[10] = '<div class="item"><img alt="" src="/Slides/d.jpg"></div>';
我怎么能随意选择10的5，然后将其输出到Twitter的引导旋转木马？
<div id="myCarousel" class="carousel">
[Items go here, first one needs to get the class 'active']
</div>
