js验证源码

$(function(){
            /*表单提交时的处理方式，必需放在验证条件设置前面*/
             $.validator.setDefaults({
                 submitHandler: function(){
                    /*使用AJAX方式提交表单*/
                     $.ajax({
                         type:"POST",
                         url:"phpscript/cmd_User.php?cmd=add",
                         data:{validateNum:$("#validateNum").val(),
                               username:$("#username").val(),
                               pwd:$("#pwd").val(),
                               email:$("#email").val(),
                               qq:$("#qq").val()
                              },
                         dataType:"json",
                         cache:false,
                         success:function(json){
                            if(json.success=="true"){
                                  $("#reginfo").html("注册成功，系统现将为你自动登录。");
                                  $("#reginfo").css("color","green");
                                  setTimeout(sendIndex,1500);
                             }else{
                                  $("#reginfo").html("注册失败，请检查是否填写正确。");
                                  $("#reginfo").css("color","red");
                             }
                         }
                     });
                    //form1.submit();
                 }
             });
            
            /*验证条件设置*/
             $("#regform1").validate({
                 event:"blur",
                    rules:{
                     validateNum:{required:true,number:true,remote:"phpscript/validateNum.php"},
                     username:{required:true,rangelength:[2,20],remote:"phpscript/exist_User.php"},
                     email:{required:true,email:true,maxlength:250},
                     pwd:{required:true,rangelength:[4,16]},
                     pwd2:{required:true,equalTo:'#pwd'},
                     qq:{required:false,number:true,rangelength:[5,12]}
                    },
                    messages:{
                         validateNum:{remote:"请输入正确的验证码"},
                         username:{remote:"用户名已经存在"}
                    }
             });
        });

php脚本源码

<?php
        Header("Cache-Control","no-store");
        Header("Pragma","no-cache");
        Header("Expires", "0");
        session_start();
        include_once ('../include/mysql.inc.php');
        $mysqli= new mysqli(DBHOST,DBUSER,DBPWD,DBNAME,DBPORT);
        $mysqli->set_charset(DBCHAR);
        $sql = "select * from ".DBPREFIX."users where username='{$_GET['username']}'";
            $result = $mysqli->query($sql);
            $count = $mysqli->affected_rows;
            if($count == 1){
                echo "false";
             }else{
                echo "true";
             }
        ?>

很多示例都没有给出php脚本返回参数的形式，这里注重说明一下，php验证脚本只能返回"false"或者"true"，其他的不能有任何的输出
