本文介绍了三种不同的方法来实现从请求中获取race号，并在获取值为null时使用设定值的逻辑。第一种方法是通用处理，通过迭代raceNoList并设置选项；第二种方法针对信息处理，同样使用迭代但增加了selected属性；第三种方法引入了Java代码，利用迭代和动态生成选项值。

arraylist的初期值取得。在spec上寫著是：從request取得所需要的race號，如果取得的該race號為null，則使用設定的值。現在我這邊有3種處理，因還不確定，故先備份一下：

1. 共通處理的

          <bean:select property="raceNo">
          <logic:iterate id="list" name="tohyoselect_include_form" property="raceNoList">
            <logic:equal name="list" value="1">
                     <html:option value="1">1R</html:option>
                    </logic:equal>
            <logic:equal name="list" value="2">
                     <html:option value="2">2R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="3">
                     <html:option value="3">3R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="4">
                     <html:option value="4">4R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="5">
                     <html:option value="5">5R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="6">
                     <html:option value="6">6R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="7">
                     <html:option value="7">7R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="8">
                     <html:option value="8">8R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="9">
                     <html:option value="8">8R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="10">
                     <html:option value="10">10R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="11">
                     <html:option value="11">11R</html:option>
                    </logic:equal>
                    <logic:equal name="list" value="12">
                     <html:option value="12">12R</html:option>
                    </logic:equal>
       </logic:iterate>
          </bean:select><br />

2.情報信息處理的

   <bean:select property="raceNo">
    <logic:iterate id="raceno" name="_f_pwtinf_oddssearchForm" property="raceNo">
     <logic:equal name="raceno" value="1">
      <option value="1" selected="selected">1R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="1">
      <option value="1">1R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="2">
      <option value="2" selected="selected">2R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="2">
      <option value="2">2R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="3">
      <option value="3" selected="selected">3R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="3">
      <option value="3">3R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="4">
      <option value="4" selected="selected">4R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="4">
      <option value="4">4R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="5">
      <option value="5" selected="selected">5R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="5">
      <option value="5">5R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="6">
      <option value="6" selected="selected">6R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="6">
      <option value="6">6R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="7">
      <option value="7" selected="selected">7R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="7">
      <option value="7">7R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="8">
      <option value="8" selected="selected">8R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="8">
      <option value="8">8R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="9">
      <option value="9" selected="selected">9R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="9">
      <option value="9">9R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="10">
      <option value="10" selected="selected">10R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="10">
      <option value="10">10R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="11">
      <option value="11" selected="selected">11R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="11">
      <option value="11">11R</option>
     </logic:notEqual>
     <logic:equal name="raceno" value="12">
      <option value="12" selected="selected">12R</option>
     </logic:equal>
     <logic:notEqual name="raceno" value="12">
      <option value="12">12R</option>
     </logic:notEqual>
       </logic:iterate>
   </bean:select>

3.馬強寫的，帶java代碼的，也先備份下

   <bean:select name="_f_pwtinf_exhibandweatherForm" property="raceNo">
       <logic:iterate id="list" name="_f_pwtinf_exhibandweatherForm" property="raceNoList" indexId="idx">
        <html:option value='<%= "raceNoList["+idx+"]" %>'>
         <bean:write name='<%= "raceNoList["+idx+"]" %>' />R
        </html:option>
      </logic:iterate>
      </bobean:select>
