request.getParameter("Submit")取不到值???
我的jsp代码是:
<%@ page language="java" pageEncoding="UTF-8"
contentType="text/html; charset=UTF-8"%>
<%@ include file="/taglibs.inc.jsp" %>
<html>
<head>
<title>写信</title>
</head>
<body>
<form action="sendMail.do" enctype="multipart/form-data" method="post">
<script language="javascript">
<!--
function addContact(type) {
var vReturnValue = window.showModalDialog("goselect.jsp",window,"dialogWidth=800px;dialogHeight=600px");
var theform = document.forms[0];
if (vReturnValue == undefined)
{
vReturnValue = "";
}
if (type=="to")
{
if (theform.txtTo.value=='')
{
theform.txtTo.value=vReturnValue;
}
else if (vReturnValue != "")
{
theform.txtTo.value += "," + vReturnValue;
}
}
else if (type=="cc")
{
if (theform.txtCC.value=='')
{
theform.txtCC.value=vReturnValue;
}
else if (vReturnValue != "")
{
theform.txtCC.value += "," + vReturnValue;
}
}
else
{
if (theform.txtBCC.value=='')
{
theform.txtBCC.value=vReturnValue;
}
else if (vReturnValue != "")
{
theform.txtBCC.value += "," + vReturnValue;
}
}
}
