freemarker list (长度,遍历,上标,嵌套,排序)
freemarker list (长度,遍历,下标,嵌套,排序) 1. freemarker获取list的size:
Java ArrayList<String> list = new ArrayList<String>();
Freemaker ${list?size}
2.list的遍历: <#list animals as being>
<tr>
<td>${being.name}${being.price}<td>
</tr>
</#list>
3.list
遍历中的下标序号:_index是list的一个属性 <#list list as a>
${a_index}
</#list>
4. list的嵌套:
<#list jsskList as jsskVO>
<#list kcList as kcVO>
<#if kcVO.kch=jsskVO.kch>
(
kcVO里有编号和名称,而jsskVO里只有编号) ${kcVO.kcm}
</#if>
</#list>
</#list>
5. list排序: 升序.sort_by()
<#list list?sort_by("字段") as x>
</#list>
降序.sort_by()?reverse <#list list?sort_by("字段")?reverse as x>
</#list>
