。。。。
。。。
function del(person_id)
{
document.frm.change.value="shanchu";
document.frm.shanchu.value=person_id;
frm.submit();
}

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：

extremeComponents 的删除 和编辑弹出页面 实现

imagePath="${pageContext.request.contextPath}/images/table/*.gif"

</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"

imagePath="${pageContext.request.contextPath}/images/table/*.gif"
