The following different formarts are supported: * {for $var=$start to $end} simple loop with step size of 1. * {for $var=$start to $end step $step} loop with individual step size. {forelse} is executed when the loop is not iterated. {for}、{forelse}标签用来创建一个简单循环，支持以下不同的格式： {for $var=$start to $end}步长为1的简单循环； {for $var=$start to $end step $step}其它步长循环。当循环无迭代时执行{forelse}。 **Attribute： ** | Attribute Name | Shorthand | Type | Required | Default | Description | |-----|-----|-----|-----|-----|-----| | max | n/a | integer | no | *n/a* | Limit the number of iterations | **Option Flags:** | **Name** | **Description** | |-----|-----| | nocache | Disables caching of the {for} loop | **属性： ** | 属性名 | 简写 | 类型 | 是否必须 | 缺省值 | 描述 | |-----|-----|-----|-----|-----|-----| | max | n/a | int | no | *n/a* | 迭代的最大次数 | **选项标记：** | **名称** | **描述** | |-----|-----| | nocache | 禁止{for}循环缓存 | <table width="100%" border="0" cellpadding="0" cellspacing="0" class="EXAMPLE"><tr><td><div class="EXAMPLE"> <a name="AEN727" id="AEN727"> </a> <b><span class="PROGRAMLISTING">Example 7.27.
