如题，废话不多说。
JSP页面
hello.jsp
<%@ page contentType="text/html; charset=GBK" %>
<html>
<head>
<title>AJAX提交页面</title>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<script type="text/javascript" src="ajax.js"></script>
<script type="text/javascript">
function doso(){
var url = "actAction.do";
var s="武晓强斯蒂芬34-*(&_(*!$^_*!&#!^$+!*#&&";
s=encodeURIComponent(s); //转换特殊字符
var parameter ="name="+s+"&email=abc@abc.com&www=http://wxq594808632.blog.163.com/";
var method = "POST";
function callBack(text){ //回调函数
alert("调用成功!\n名字为:"+text);
}
new Ajax().ajaxRequest(url,parameter,method,callBack); //调用方法发送Request
}
</script>
</head>
<body>
<input type="button" value="提交" onclick="doso()"/>
</body>
</html>
java类
ActAction.java
package ajaxpost;

HttpServletRequest request,
HttpServletResponse response) throws
UnsupportedEncodingException {
//设置字符编码返回的编码
response.setContentType("text/html;charset=UTF-8");
//接收字符的编码
try {
request.setCharacterEncoding("UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
PrintWriter out = null;
try {

} catch (IOException ex) {
ex.printStackTrace();
}
String name = request.getParameter("name");
String email = request.getParameter("email");
String www = request.getParameter("www");
System.out.println(email);
System.out.println(name);
System.out.println(www);
// out.print(name+"\n"+email+"\n"+www);
out.print(name); //返回值
return null;
}
}
最重要滴
