> 轮播插件就是将几张同等大小的大图，按照顺序依次播放

<div id="myCarousel" class="carousel slide" style="width:690px;">
        <ol class="carousel-indicators">
            <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
            <li data-target="#myCarousel" data-slide-to="1"></li>
            <li data-target="#myCarousel" data-slide-to="2"></li>
        </ol>
        <div class="carousel-inner">
            <div class="item active">
                <img src="../img/11.jpg" alt="第一张">
                <div class="carousel-caption">
                    <h3>Free</h3>
                    <p>I want to flee with the balloon</p>
                </div>
            </div>
            <div class="item">
                <img src="../img/22.jpg" alt="第二张">
                <div class="carousel-caption">
                    <h3>Alone</h3>
                    <p>I'm not alone only when I miss you</p>
                </div>
            </div>
            <div class="item">
                <img src="../img/33.jpg" alt="第三张">
                <div class="carousel-caption">
                    <h3>Yes,I do</h3>
                    <p>Marry me,please</p>
                </div>
            </div>
        </div>
        <a href="#myCarousel" data-slide="prev" class="carousel-control left">‹</a>
        <a href="#myCarousel" data-slide="next" class="carousel-control right">›</a>
    </div>

data属性解释：  
1.data-slide接受关键字prev和next，用来改变幻灯片相对于当前位置的位置  
2.data-slide-to来向轮播底部创建一个原始滑动索引，data-slide-to=”2”将把滑动块移动到一个特定的索引，索引从0开始计数  
3.data-ride=”carousel”属性用户标记轮播在页面加载时开始动画播放  
效果图如下：  
![SouthEast][]  
![SouthEast 1][]

        // 设置暂停轮播事件
        pause:'hover',
        // 只播一次
        wrap:false
    });
