         <p><em>foreach</em> 元素的功能非常强大，它允许你指定一个集合，声明可以在元素体内使用的集合项（item）和索引（index）变量。它也允许你指定开头与结尾的字符串以及集合项迭代之间的分隔符。这个元素也不会错误地添加多余的分隔符，看它多智能！</p>
         <p><span class="label important">提示</span> 你可以将任何可迭代对象（如 List、Set 等）、Map 对象或者数组对象作为集合参数传递给 <em>foreach</em>。当使用可迭代对象或者数组时，index 是当前迭代的序号，item 的值是本次迭代获取到的元素。当使用 Map 对象（或者 Map.Entry 对象的集合）时，index 是键，item 是值。</p>
