counter is used to print out a count. counter will remember the count on each iteration. You can adjust the number, the interval and the direction of the count, as well as determine whether or not to print the value. You can run multiple counters concurrently by supplying a unique name for each one. If you do not supply a name, the name 'default' will be used.
counter 用于输出一个记数过程. counter 保存了每次记数时的当前记数值. 用户可以通过调节 interval 和 direction 调节该值. 也可以决定是否输出该值. 如果需要同时运行多个计数器,必须为它们指定不同的名称. 如果没有指定名称,模板引擎使用 "default" 作为缺省值.
If you supply the special "assign" attribute, the output of the counter function will be assigned to this template variable instead of being output to the template.
如果指定了 "assign" 这个特殊属性,该计数器的输出值将被赋给由 assign 指定的模板变量,而不是直接输出.
