    <form id="form1" action="" >
            <input type="text" name="username"><br>
            <input type="text" name="password"><br>
            <input type="button" value="登录" id="but1">

    $('#but1').click(function(){
    $('#form1').attr({'action':"${pageScope.basePath}login",'method':"post"}).submit();
    });
    </script>
</html>

$.ajax

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%    
String path = request.getContextPath();    
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

  <body>
    <div>
    <form id="form1" action="" >
            <input type="text" name="username"><br>
            <input type="text" name="password"><br>
            <input type="button" value="登录" id="but1">
    </form>
    </div>
    <script type="text/javascript">
    $('#but1').click(function(){
        var user={username:"sunfan",password:'helloworld'};
        $.ajax({
            url:"login", //访问地址--action地址
            type:"post", //提交方式
            data:user,   //提交给服务器的数据
            success:function(reData){ //回调函数的处理方式
            alert(reData);
            }
        });
    });
    </script>
</html>

$.post

$('#but1').click(function(){
        var user={username:"sunfan",password:'helloworld'};
           $.post( //提交方式
              "login", //访问地址
              user,   //提交给服务器的数据
              function(reData){//回调函数的处理方式
              alert(reData);
              }
           );
    });

$.get与post类似只是提交的方式不同

$('#but1').click(function(){
        var user={username:"sunfan",password:'helloworld'};
           $.get(
              "login",
              user,
              function(reData){
              alert(reData);
              }
           );
    });
