  • 只选择年份的下拉菜单

    只选择年份的下拉菜单

    第一种:在jsp页面中写入java代码,这是网上搜到的,不过感觉不是很好。代码如下:

         <select name="year1" style=" 90px;">
         <option value="">--- 请选择 ---</option> 
                  <% 
                         StringBuffer bufYear = new StringBuffer(); 
                         //下拉列表的年数 
                         for(int i=0;i<11;i++){ 
                         //最小年 
                         int iYear = 2005+i; 
                         bufYear.append("<option value = '"+iYear+"'"); 
                         Date date = new Date(); 
                         int sYear = date.getYear(); 
                         //系统时间从1900年开始 
                         int sYearc = sYear+1900;  
                         if(iYear == sYearc){  
                              bufYear.append(" selected");  
                          } 
                         bufYear.append(" >"+iYear+"</option> "); 
                         } 
                         out.println(bufYear.toString()); 
                   %> 
          </select>- 
         <select name='year2' style=" 90px;"> 
           <option value="">--- 请选择 ---</option>
                  <% 
                         StringBuffer bufYear2 = new StringBuffer(); 
                         //下拉列表的年数 
                         for(int i=0;i<11;i++){ 
                         //最小年 
                         int iYear2 = 2005+i; 
                         bufYear2.append("<option value = '"+iYear2+"'"); 
                         Date date = new Date(); 
                         int sYear2 = date.getYear(); 
                         //系统时间从1900年开始 
                         int sYearc2 = sYear2+1900;  
                          if(iYear2 == sYearc2){  
                              bufYear2.append(" selected");  
                          } 
                         bufYear2.append(" >"+iYear2+"</option> "); 
                         } 
                         out.println(bufYear2.toString()); 
                   %> 
          </select>  

    第二种,本人采用过,就是借用jsp自带的foreach标签。代码如下:

    其中集合years需要自己定义,本人是在action中定义赋值后放到actioncontent中的。

    Action代码:ActionContent.getContent.put("years",years);

    jsp代码:

         <select id="year1" name="year1" style="90px;">
         <option value="">--- 请选择 ---</option>
                   <c:forEach var="per" items="${years}">
           <option <c:if test="${per==year1}">selected="selected"</c:if>>${per}</option>
          </c:forEach>
         </select>-   
         <select id="year2" name="year2" style="90px;">
         <option value="">--- 请选择 ---</option>
                   <c:forEach var="per" items="${years}" >
           <option <c:if test="${per==year2}">selected="selected"</c:if>>${per}</option>
          </c:forEach>
         </select>

    第三种:本人采用的s标签中的iterater标签。以选取办公室地点为例:

    action代码:ActionContent.getContent.put("roomList",roomList);

    jsp代码:

    <select id="place" name="place" style="172px" class="required">
       <option value="">-- 请选择 --</option>
       <s:iterator id="tc" value="#roomList">
         <option value='<s:property value="#tc.name" />'
          <s:if test="%{#tc.name == model.place}">selected="selected"</s:if>>
          <s:property value="#tc.name" />
         </option>
          </s:iterator>
      </select>
