freemarker写select组件

1、宏定义

<#macro select id datas value="" key="" text="" headKey="" headValue="">
     <select id="${id}" name="${id}">
          <option>---请选择---</option>
          <#if headKey!="">
               <option value="${headKey}">${headValue}</option>
          </#if>
          <#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>
     </select>
</#macro>

2、引入宏

<@items.select id="username" datas=users key="userNo" text="userName" headKey="0" headValue="其他"/>

3、示例结果

<select id="username" name="username">
          <option>---请选择---</option>
               <option value="0">其他</option>
                   <option value="1">张三丰</option>
                   <option value="2">李思思</option>
                   <option value="3">赵武</option>
                   <option value="4">刘雪</option>
                   <option value="5">朱顾</option>
                   <option value="6">赵武</option>
                   <option value="7">吴语</option>
                   <option value="8">血玉</option>
     </select>
