freemarker寫select組件

1、宏定義

<#macro select id datas value="" key="" text="" headKey="" headValue="">     <select id="${id}" name="${id}">          <option>---請選擇---</option>          <#if headKey!="">               <option value="${headKey}">${headValue}</option>          </#if>          <#if datas?is_hash_ex>             <#local keys=datas?keys/>             <#list keys as key>                  <#if key==value>                      <option value="${key}" selected>${datas[key]}</option>                  <#else>                      <option value="${key}">${datas[key]}</option>                  </#if>             </#list>          <#else>             <#list datas as data>              <#if key!="">                  <#if value == data[key]?string>                 <option value="${data[key]}" selected>${data[text]}</option>                  <#else>                   <option value="${data[key]}">${data[text]}</option>                 </#if>              <#else>                  <#if value == data>                 <option value="${data}" selected>${data}</option>                 <#else>                 <option value="${data}">${data}</option>              </#if>             </#if>           </#list>        </#if>               </select></#macro>

2、宏引入

<@items.select id="sex" datas={"0":"請選擇學曆","1":"小學","2":"初中","3":"高中","4":"本科"} />

3、運行結果

<select id="sex" name="sex">          <option>---請選擇---</option>                      <option value="0">請選擇學曆</option>                      <option value="1">小學</option>                      <option value="2">初中</option>                      <option value="3">高中</option>                      <option value="4">本科</option>               </select>
