我有一个数组，是否可以使用 freemarker 将此数组拆分为子数组。

Freemaker模板如何将现有数组拆分为子数组

<#assign monthsOfTheYear = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"] />

"January", "February", "March", "April" and "October", "November", "December"

"January", "February", "March"- 应该在 1 个数组和 .

"October", "November", "December"-- 应该是第二个数组

  • 是的，可以将数组动态拆分为子数组，其中一种方法如下。
  • 下面是它的一个例子
<#assign first = monthsOfTheYear[1..4] />
<#assign second = monthsOfTheYear[6..9] />
  • 如果它是一个字符串，你可能不得不转换成一个数字，假设 startdate 和 enddate 是字符串，值为 02 和 04
<#assign sublistVar = monthsOfTheYear[(startdate?number-1)..(enddate?number-1)] />
