使用JavaScript通过在表单里加入隐藏域信息，然后用表单提交的方式把数据传递给JSP程序

Example(1)

代码 

<script type="text/javascript" language="javascript">
 function f(){
 document.forms["form1"].test.value =document.forms["form1"].cloze.value+ " hello";  //获取jsp中表单的值
 document.form1.submit();
 }
</script> 
  
  <body>
    <%
     String s=new String();
     String t=request.getParameter("test");
     if(t!=null){
    %>
    你填写的值：<%=t %><br>
    <%} %>
    
    <form name="form1" method="post" action="regist.jsp">
    <input type="text" name="cloze" />
    <input type="hidden" name="test" value=<%=s %>  />
    <input type="button" value="submit" onclick="f()" />
    </form>
      
  </body>

 


javascript 传递json js传值给jsp_表单

 


javascript 传递json js传值给jsp_javascript_02

 

 

Example2:

 

代码
1、test.jsp 

<%@ page contentType="text/html; charset=gb2312" %>

<%
  String s1="Hello ";
  String s2="World!!";
%>

<script language="JavaScript">

function insertclick(){
  var1 ="<%=s1 %>"; 
  document.forms["insertForm"].mc.value = var1 + document.forms["insertForm"].mc.value ;
  document.insertForm.submit();
}
</script>


<form name="insertForm" method="post" action="get.jsp">
<input type="hidden" name="mc" value="<%=s2 %>">
<input type="button" value="提交" onclick="insertclick()">
</form>


2、get.jsp
<%
  String strVar1=request.getParameter("mc");
  out.print(strVar1);
%>
