extremeComponents 的删除 和编辑弹出页面 实现

1。分页信息输出
<div align="center" id="cz"  >
<ec:table
         action="${pageContext.request.contextPath}/BmServlet"
         items="arrayBM"
         var="a"
         imagePath="${pageContext.request.contextPath}/images/table/*.gif"
         width="99%"
         tableId="resultTable1"
         rowsDisplayed="10"
         form="frm"
         filterable="false"
         sortable="false"
        autoIncludeParameters="false">
<ec:row>
<ec:column property="city_id" title="【所属地市】" width="16%"></ec:column>
  <ec:column property="county_id" title="【分县公司】" width="16%"></ec:column>
   <ec:column property="bm_id" title="【所属部门】" width="16%"></ec:column>
       <ec:column property="person_id" title="【员工工号】" width="16%"></ec:column>
       <ec:column property="person_name" title="【员工姓名】" width="16%"></ec:column>
      
       <ec:column property="【编辑】" title="" width="10%">
       <input type="button" value="编辑" name="space">
        </ec:column>
       
       <ec:column property="【删除】" title="" width="10%">
      <input type="button" value="删除" onclick="del('${a.person_id }')">
            </ec:column>
              
</ec:row>
</ec:table>
<input type="hidden"  name="shanchu">
</div>
2。
。。。。
。。。
function del(person_id)
{
document.frm.change.value="shanchu";
document.frm.shanchu.value=person_id;
frm.submit();
}
</script>

3。servlet 获取参数 然后 连接数据库 执行删除
。。。
。。。。
if(param.equals("shanchu"))
{
String person_id=request.getParameter("shanchu");
//写SQL语句 删除
System.out.println("%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%");
System.out.println(person_id);
System.out.println("%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%");
    }
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
编辑
思路：用分页组件 extremecomponents 实现 编辑
然后 传参数
用JS实现 弹出页面
页面上是用JSP
然后用的是 JS限制格式
JSP action=到 SERVLET
SERVLET 获取 参数
连接数据库 update 数据 即可
很清晰的思路哦
代码：
<div align="center" id="cz"  >
<ec:table
         action="${pageContext.request.contextPath}/BmServlet"
         items="arrayBM"
         var="a"
         imagePath="${pageContext.request.contextPath}/images/table/*.gif"
         width="99%"
         tableId="resultTable1"
         rowsDisplayed="10"
         form="frm"
         filterable="false"
         sortable="false"
        autoIncludeParameters="false">
<ec:row>
<ec:column property="city_id" title="【所属地市】" width="16%"></ec:column>
  <ec:column property="county_id" title="【分县公司】" width="16%"></ec:column>

       <ec:column property="person_id" title="【员工工号】" width="16%"></ec:column>
       <ec:column property="person_name" title="【员工姓名】" width="16%"></ec:column>
      
       <ec:column property="【编辑】" title="" width="10%">
       <input type="button" value="编辑" onclick="edit('${a.person_id }','${a.city_id }','${a.county_id }','${a.bm_id }','${a.person_name }')" >
        </ec:column>
       
       <ec:column property="【删除】" title="" width="10%">
      <input type="button" value="删除" onclick="del('${a.person_id }')">
             </ec:column>
