$("#resultDiv").html("<font color='#03bb74'>报名成功！</font>");
}else{
$("#resultDiv").html("<font color='#eb2700'>报名失败！</font>");
}
},

$("#resultDiv").html("<font color='#eb2700'>报名失败！</font>");
}
});

服务器端：

public void AjaxMake()
{
String callbackFunName = Request["callbackparam"];

string name = Request["xingming"];
string phone = Request["phone"];
string sex = Request["sex"];
int renshu = Convert.ToInt32(Request["renshu"]);
string bName = Request["bName"];
renshu = renshu > 20 ? 20 : renshu;
bool result = KftBLL.MakeMan(0, name, phone, sex, bName, renshu);
if (result)
{
Response.Write(callbackFunName + "([ { \"msg\":\"OK\"}])");
}
else
{
Response.Write(callbackFunName + "([ { \"msg\":\"err\"}])");
}
}
