ajax与JQuery结合拓展记录

jquery与ajax结合

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>









	

	

	

post请求方式：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>









	

	

	

用的servlet

package cn.dzz.web.servlet1;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class Bservlet
 */
@WebServlet("/Bservlet")
public class Bservlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		response.setContentType("text/html;charset=utf-8");//从servlet中响应回ajax的数据编码问题
		
		request.setCharacterEncoding("UTF-8");//请求体参数数据中解决中文乱码，编码问题
		String username = request.getParameter("username");
		
		System.out.println(username);
		
		response.getWriter().print("ajak+JQuery");
		
	}
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		response.setContentType("text/html;charset=utf-8");//从servlet中响应回ajax的数据编码问题
		
		request.setCharacterEncoding("UTF-8");//请求体参数数据中解决中文乱码，编码问题
		//获取请求参数
		String username = request.getParameter("username");
		System.out.println(username);
		
		response.getWriter().print(username);
	}

}

完毕。
