关于Bootstrap模态框和table互相传值，以及实现图片上传

学习过Boostrap模态窗口，一直想用Bootstrap的模态窗口实现数据的更新操作，最近刚好遇到这个问题，然后就研究了一下。

一、纯数据的传递

如果是纯数据的传递，只要从table表中获取行信息，然后在Bootstrap模态窗口中进行数据的回填即可。

关键代码：

			

				

					

						×
						
修改信息
					
					

						

							

								
编       号：
								

								

							
							

								
商品名称：
								

								

							
							

								
商品价格：
								
	
								
							
							
							

								
商品分类：
								

								

							

						
					
					

						关闭
						提交更改
					
				
				
			
			
		

GoodsQueryServlet.java

package com.cate.action.goods;



import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.cate.DAO.FoodGoodsDAO;
import com.cate.DAO.DAOImpl.FoodGoodsDAOImpl;


//食品查询

public class GoodsQueryServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		FoodGoodsDAO dao = new FoodGoodsDAOImpl();
		List> rslist = new ArrayList<>();
		
		try {
			rslist = dao.query();
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		request.setAttribute("rslist", rslist);
		request.getRequestDispatcher("manage/goods/goodQuery.jsp").forward(request, response);
		//request.getRequestDispatcher("front/meishi.jsp").forward(request, response);
	}

	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		request.setCharacterEncoding("utf-8");
	
	}

}

DAO实现了类FoodGoodDAOImpl.java
