freemarker list (长度,遍历,下标,嵌套,排序)

1. freemarker获取list的size ：

${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>  

6. list标签遍历map：

  

 <#list avertisementTypeMap?keys as key>   
        <option value="${key}">${avertisementTypeMap[key]}</option>   
    </#list>  

<#assign numbers = ["一","二","三"] + ["四","五","六"]+["七","八","九","十"]/> 
<#assign page = 2 />
<#assign pageNum = 10 />
<#assign n = (page-1)*pageNum />
<#list numbers as x>
	 <#assign n = n+1 />
	${n}:${x}:${x_index+1}<br />
</#list>
