下面程序为什么GET可以POST就不可以？
下面这个程序有点怪， 如果表单是这样的
<form enctype= "multipart/form-data " action= "submit.jsp " method= "post " name= "form1 ">
request收到的值全是NULL
而当改成
<form enctype= "multipart/form-data " action= "submit.jsp " method= "get " name= "form1 ">
时， 就能正确收到request值
这是为什么呢？
<%@ page contentType= "text/html; charset=gb2312 " %>
<%@ page language= "java " import= "com.fredck.FCKeditor.* " %>
<%@ page import= "com.oa2007.tool.* "%>
<link rel= "stylesheet " type= "text/css " href= "../../../../theme/1/style.css ">
<script language= "javascript ">
function highlight(obj){
var hightlightBgColor = '#d6d6d6 ';
obj.onmouseover = function(){
var o = event.srcElement;
if(o.tagName== "TD "){
with(o.parentElement){
style.backgroundColor = hightlightBgColor;
}
}
}
obj.onmouseout = function(){
var o = event.srcElement;
if(o.tagName== "TD "){o.parentElement.style.backgroundColor = ' ';}
}
}
</script>
<html>
<head>
<title> 发布新闻 </title>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<script Language= "JavaScript ">
function CheckForm()
{
if(document.form1.SUBJECT.value== " ")
{ alert( "新闻的标题不能为空！ ");
return (false);
}
return (true);
}
function sendForm()
{
if(CheckForm())
document.form1.submit();
}
</script>

[解决办法]
如果我没记错的话，post和get方法的区别是处理少量数据和大量数据的，你再查查看，呵呵，怕误导你！
[解决办法]
enctype= "multipart/form-data " 这种方式 REQUEST不能直接用GETPARAMETER获得变量。
