FreeMarker grammer

1. Map

Render the values of a Map

The following code snippet shows how to get the values of a Map (e.g. HashMap) from within a Freemarker template.

<#assign m = myMap>

<#assign values = m?values>

         

<ul>

     <#list values as myObject>

     <li>${myObject.myPropery}</li>

     </#list>

</ul>

 

Render the keys of a Map

You can do a similar thing with the keys of a map as shown below.

<#assign m = myMap>

<#assign keys = m?keys>

         

<ul>

     <#list keys as key>

     <li>${key}</li>

     </#list>

</ul>

 

 

<#foreach friendId in entry.commonFriends>
//friendId 是int类型
<#if results.commonFriendsProfileMap[friendId?string]??>

//friendId?string 将int转为string类型,commonFriendsProfileMap的value值为一个对象
${results.commonFriendsProfileMap[friendId?string].name}
${results.commonFriendsProfileMap[friendId?string].photoUrl}
</#if>
</#foreach>

 

2.list

 

<#assign pageStart=results.listPageStart>
<#assign pageEnd=results.listPageEnd>
<#list pageStart..pageEnd as index>
<#if results.currentPage == index>
${index}
</#if>
</#if>
</#list>

 

<#list entry.object.skills as skill>
<#if skill_index &lt; 3 >
//list里是对象，只在list里取三个
${skill.skill_name} |${skill.skill_level}

</#if>
</#list>

3. if else 

 

<#if entry.count &gt; 1000>
<#elseif entry.count ==2>

<#else>

</#if>
