实现javaWeb对数据库的增删改查-MVC开发思想-Controller层之删除记录

• 1.在WebContent目录下新建scripts文件夹，导入jQuery库，并更改index.jsp前端页面

<%@page import="com.njupt.javaweb.business.Customer"%>
<%@page import="java.util.List"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>



	
	
	
	
	


	

		

			

				
名称:
				

			
			

				
地址:
				

			
			

				
手机号:
				

			
			

				

				
创建用户
			
		
	
	

	

	

	

	

	<% 
		List listCustomer =(List)request.getAttribute("listCustomer");
	  	if( listCustomer!=null && listCustomer.size()>0){
	%>
	
	
	<%
			for(Customer cus : listCustomer){
	%>
				
	<%
	  		}
	  	}
	%>

<%= cus.getId() %>
					
<%= cus.getName() %>
					
<%= cus.getAddress() %>
					
<%= cus.getPhone() %>
					
Modify
					
Delete
				

效果图

• 编写Customer中 的delete函数

  	private void delete(HttpServletRequest request, HttpServletResponse response){	
  		System.out.println("delete");
  		int id=0;
  		try {
  			id = Integer.parseInt(request.getParameter("id"));
  			customerDAOJdbcImp.delete(id);	
  			response.sendRedirect("index.jsp");
  		} catch (Exception e) {
  			// TODO: handle exception
  			e.printStackTrace();
  		}
  		
  	}
