通铭派瑞监考代码管理总结

1.参数传递:
    jsp页面用herf方式/get方式传递参数:
      <a href="<%=path %>/en/learner/jsp/user_home/uh_frame/jkdmxg.jsp?name=<%=name %>&id=<%=id %>&code=<%=code%>">编辑</a>
    jsp页面接受get方式传递的参数:
      String id=(String)request.getParameter("id");
    jsp页面get方式传递参数时的乱码解决:
      String nn=request.getParameter("name");
      String name=new String(nn.getBytes("ISO-8859-1"),"UTF-8");
 
2.表单提交:
   页面中有from表单时,可以直接提交到别的jsp页面,from表单的值会默认在request中,直接在页面中用request.getParameter("name");方式就可以取到值.
   2.1js方式提交表单到jsp页面:
        <form action="" name="jkdmxg" id="jkdmxg">
        名称:<input id="jkdm_name" type="text" value=<%=name%> name="jkdm_name">
        监考代码:<input id="jkdm_code" type="text" value=<%=code%> name="jkdm_code">
        <input type="hidden" name="jkdm_id" value="<%=id%>" id="jkdm_id">
                 <input id="quxiao" type="button" value="取消" onclick="quxiao1();">
        <input id="queding" type="button" value="修改" onclick="queding1();">
        </form>
     javascript方法:
       function queding1(){
        var name1=document.jkdmxg.jkdm_name.value;  
        var code1=document.jkdmxg.jkdm_code.value;
        if(name1==null||code1==null||name1==''||code1==''){
         alert("名称或监考代码不能为空!");
         return null;
        }else{
         document.jkdmxg.action ='<%=path %>/en/learner/jsp/user_home/uh_frame/jkdmxg1.jsp';
         document.jkdmxg.submit();
        }
       }
3.页面跳转
    jsp页面之间的跳转:
       <%response.setContentType("text/html; charset=utf-8");
                response.sendRedirect(path+"/en/learner/jsp/user_home/uh_frame/jkdmgl.jsp?isok="+isOk);%>
       
4 工作中遇到的问题:
  4.1 在myEclipse中clean后,tomcat和本地工程的classes文件夹下都没有文件,重新编译也不行,试了一切办法都没解决好,最后把本地和myeclipse中的
   dh_home工程删除掉,重新检出一份才可以.
  4.2 新建的java类在myeclipse中不编译,最后发现时jdk版本错误,把1.6的版本换成1.4的版本就行了.
  
5.dh_home工程中的表的查询和修改
