在servlet中检查选择了哪个checkbox，并根据该进程检查所有其他数据。例如，如果你的HTML看起来像这样：

<table border="1" cellpadding="6" cellspacing="4" 
       style="border-collapse: collapse" width="200%" id="AutoNumber1"
       align="center" bordercolorlight="#800000" bordercolordark="#800000 " class="left" >
     <tr>
         <td width="5%" align="center">
           <input type="checkbox" id="checkbox_1" value=<%= id%>/>
           <font face="Arial" size="3" color="light blue">
             Options1</font>
       </td>
       <td width="15%" align="center">
         <font face="Arial" size="3" color="light blue">
          Title</font><input id="title_1" />
       </td>
       <td width="40%" align="center">
         <font face="Arial" size="3" color="light blue">
          Description</font><input id="description_1" />
       </td>

    </tr>
         <tr>
         <td width="5%" align="center">
           <input type="checkbox" id="checkbox_2" value=<%= id%>/>
           <font face="Arial" size="3" color="light blue">
             Options2</font>
       </td>
       <td width="15%" align="center">
         <font face="Arial" size="3" color="light blue">
          Title</font><input id="title_2" />
       </td>
       <td width="40%" align="center">
         <font face="Arial" size="3" color="light blue">
          Description</font><input id="description_2" />
       </td>

    </tr>
</table>

比在servlet中，检查是否选择了checkbox_1？如果是，则处理title_1和description_1。并为checkbox_2，title_2＆amp;采用相同的逻辑description_2

使用复选框发送多个值
