thinkphp标签实现bootsrtap轮播carousel实例
由于轮播carousel第一个div需要设置active样式才能正常显示，上面的圆点也同样需要数字，
使用volist标签在循环的同时可以取得下标（foreach，for标签实现不了）

<div class="container">
<!-- carousel -->
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<volist name="bopic" id="xt">
<li data-target="#carousel-example-generic" data-slide-to="{$i-1}" class="<if condition="$i eq 1 ">active</if>"></li>
</volist>
</ol>
<div class="carousel-inner">
<volist name="bopic" id="xt">
<div class='item <if condition="$i eq 1 ">active</if>'>
<img src="{$xt.page_bopic_image}" alt="{$xt.page_bopic_seo}"/>
</div>
</volist>
</div>
<a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
<!-- /.carousel -->
</div>
