如果您真的想基于索引制作该切片:

If you really want to make that slice based on indexes:

<#assign listVar = ["v1", "v2", "v3", "v4" ] />
<#assign sublistVar = listVar[0..1] />

请参见 Freemarker序列切片.

但是请注意，如果索引超出范围，它将以错误停止.根据您需要的用途，可能要改用?chunk(2).

But beware, it will stop with error if the index is out of range. Depending on what you need this for, you may want to use ?chunk(2) instead.

更新:为避免出现索引越界错误，在FreeMarker 2.3.21中，您可以发出listVar[0..*2]，它将切出2个项目，如果可用空间较小，则减少两个项目. (也可以使用专用端切片:listVar[0..<2])

Update: As of avoiding index-out-of-bounds error, in FreeMarker 2.3.21 you can issue listVar[0..*2], which will slice out 2 items, or less if there's less available. (Also exclusive-end slicing can come handy: listVar[0..<2])
