刘凝之字志安翻译:ajax使用流程【ajax详细使用步骤、ajax使用实例】

1、js方法
                                     width="138" height="40" />
2、添加js方法
function createuser() {
    if ($("#emailinfo").html().indexOf("Email地址合法") == -1) {
        checkregemail();
        changeimg();
        return false;
    }
    if ($("#spanRegtype").val() == "1") {
        if ($("#mobileInfo").html().indexOf("手机号合法") == -1) {
            checkregMobile();
            changeimg();
            return false;
        }
    }

    if ($("#repasswordinfo").html().indexOf("密码输入合法") == -1) {
        recheckpassword();
        changeimg();
        return false;
    }
    if ($("#validateinfo").html().indexOf('验证码输入正确') == -1) {
        checkvalidecode();
        changeimg();
        return false;
    }
    var $bday = "NULL";
    var $mobile = $("#txtMobile").val();
    var $cardid = $("#year").val();
    var $answer = $("#txtanswer").val();
    //开始注册用户
get传参：
    $.ajax({//ajax调用传参
        url: "/ajax.aspx?q=createuser&email=" + $("#txtemail").val() + "&mobile=" + $mobile + "&password=" + $("#txtpassword").val() + rand(100000, 999999) + "®type=" + $("#spanRegtype").val() + "&cardid=" + $cardid + "&answer=" + encodeURIComponent($answer) + "&time=" + new Date().toString(),
        type: "GET",
        timeout: 30000,
        beforeSend: function() {
            $('#status').html("正在注册中...");
        },
        error: function() {
            $("#status").addClass("redr");
            $("#status").html("注册用户失败，请重试或联系管理员！");
        },
        success: function() {
            var $status = arguments[0]; //得到返回值
            if ($status > 0) {
                window.location = ($("#referurl").val());
            }
            else {
                $("#status").addClass("redr");
                $("#status").html("注册成功");
                alert("注册成功");
                window.location = $("#fromurl").val();
            }
        }
    });
post传参：
 $.ajax({
        url: "/ajax.aspx?",
        data: {
            "q": "saveAddSKU",
            "eid": eid,
            "skulist": skulist,
            "skunum": skunum,
            "skupic": skupic,
            "picbs": picbs,
            "skupicnum": skupicnum,
            "time": new Date().toString()
        },
        type: "POST",
        timeout: 50000,
        beforeSend: function() {
        },
        error: function() {
            alert("SKU追加失败");
        },
        success: function(res) {
            if (res == "0") {
                alert("SKU追加成功");

            }
        }
    });
}
3、ajax方法
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
  {
switch (q)
                {
                    #region 根据参数不同，进行不同的操作
                    case "checkemail"://检测邮箱是否可用
                        checkRegInfo(0);
                        break;
                    case "checkloginname"://检测用户名是否可用
                        checkRegInfo(1);
                        break;
                    case "checkmobile"://检测手机号是否可用
                        checkRegInfo(2);
                        break;
                    case "createuser"://注册用户
                        createuser();
                        break;
                  #endregion
              }

  }
}
#region 注册用户 对数据进行添加
        private void createuser()
        {//调用存储过程实例
            string email = Fetch.Get("email");  //Fetch 分装类
            string password = Fetch.Get("password");
            string mobile = Fetch.Get("mobile");
            string temp = password.Substring(0, password.Length - 6);
            int regfrom = 0;
            string question = Fetch.Get("cardid");
            string rettype = Fetch.Get("regtype");
            string answer = Fetch.Get("answer");
            string userip = Page.Request.UserHostAddress;
            int result = 0;
            string msg = string.Empty;
            iuser.regUser("", temp, rettype, mobile, email, regfrom, userip, question, answer, out result, out msg);
            string itemp = result.ToString() + "@" + msg;
            password = password.Substring(0, 6);
            password = Common.Text.MD5(password);
            DataSet ds = iuser.sp_login(email, password, Fetch.UserIp, out result, out msg);
            if (ds != null && ds.Tables.Count > 0)
            {
                DataTable dt = ds.Tables[0];
                commonfunction.SaveLoginCookie(dt.Rows[0]);
            }
            Response.Write(itemp);      //打印返回值
            Response.End();
        }
        #endregion
