    <form id="form1" action="" >

            <input type="text" name="username"><br>

            <input type="text" name="password"><br>

    $('#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);

              }

           );

    });
