用jsp+servlet写一个类似于excel表格的网页表单

再DreamweaverCS5下要看到这样的效果:

需要编写jsp网页如下,这里使用了同一个表单,多个submit的分发的方法,具体可以看里面的js函数:

 

[xhtml]  view plain copy
  1. <%@ page language="java" contentType="text/html; charset=UTF-8"  
  2.     pageEncoding="UTF-8"%>  
  3.     <%@ page import="java.util.*"%>

  10. </head>  
  11. <body>  
  12.     <mce:script type="text/javascript"><!--  
  13.         //同一个表单,多个submit的js分发   
  14.         function deleteSubmit(form){  
  15.             form.submitType.value="delete";  
  16.         }  
  17.         //同一个表单,多个submit的js分发   
  18.         function updateSubmit(form){  
  19.             form.submitType.value="update";  
  20.         }  
  21.         //同一个表单,多个submit的js分发   
  22.         function addSubmit(form){  
  23.             form.submitType.value="add";  
  24.         }  
  25.       
  26. // --></mce:script>

  43.         <tr>  
  44.             <form action="SearcherSheetServlet" method="post">

用servlet来处理请求,因为是用post方法发送的参数,所以在doPost里面修改:
