遍歷圖中的Freemarker

Question

可能重複：
Freemarker iterating over hashmap keys

我有一個哈希表包含項目ID作爲一個價值的關鍵和Item對象。以下是僞代碼 -

allItems : { 
    12: itemObj1 (id:12, name:myitem1) 
    13: itemObj2 (id:13, name:myitem2) 
    14: itemObj3 (id:14, name:myitem3) 
} 

On result.ftl我需要遍歷此映射並獲取Item對象的值。我已經試過這種方法，但不能從項目對象中獲取值 -

<#list item?keys as it> 
    ${it} = ${item.get(it)[name]} 
</#list> 

Answer 1

我想你想：

<#list allItems?keys as it> 
    ${it} = ${allItems[it].name} 
</#list> 

Answer 2

<#assign seq=["a","b","c"]> 
<#list seq as l> 
    ${l[1]} 
// It will print b 
    ${l[0]} 
//It will print a 
</#list>
