                          <label for="abs-2" class="checkboxLabel">士大夫</label>
                          <input type="checkbox" name="abs" value="6" id="abs-3"/>
                          <label for="abs-3" class="checkboxLabel">按时大法师的</label>                      </td>
                      </tr>
可以发现两个列表中的checkbox的id重复了，我想请教的是 该如何使这种情况下的checkbox的id的值唯一。
谢谢

Answer 1

出现的问题是 我点击选择上边列表的checkbox 下边列表的给选择上了

Answer 2

<s:checkboxlist name="abs" list="#perm.l" listKey="x" listValue="y"/>
问题在name="abs" 你能不能让他生成一个不一样的name 比如 "abs"+当前循环的长度 作为name区分

Answer 4

                    <% int i=0;%>
                    <s:iterator id="a" value="list">
                      <tr>
                        <td bgcolor="#d4d4d4" border="0"><span style="cursor:hand">
                          <s:property value="#a.m"/><s:property value="#a.n"/>
                          </span>
                          
                      </td>
                      
                      </tr>
                      
                      <tr>
                      <td bgcolor="#FAFAFA">
                          <s:checkboxlist name="abs<%=i++%>" list="#perm.l" listKey="x" listValue="y"/>
                      </td>
                      </tr>
                    </s:iterator>

Answer 5

这样子动态生成，用你对象里的东西
<s:checkbox name="selectFlag" cssClass="checkbox1" fieldValue="%{id}"
theme="simple" />
