Login Page using ASP.Net & Ajax
- by user1293474
I'm trying to make a login page using html, ajax & ASP.NET.The data is truly passed to the ajax function, but when I debug the asp page the username and password are sent with NULL.
The code is supposed to take username & password then returns the userid
Html page:
<div id="usernameid">Username:</div><input id="username" type="text"/> <span id="username_status"></span>
<div id="passwordid">Password:</div><input id="password" type="password"/> <span id="password_status"></span>
<div> <input id="loginbutton" onclick="UserLogin()" type="submit" value="Submit" /></div>
Javascript:
function UserLogin() {
var postData = JSON.stringify({ "username": JSON.stringify($("#username").val()), "password": JSON.stringify($("#password").val()) });
alert(postData);
$.ajax({
type: "GET",
url: "http://localhost:49317/LoginPageForLearn.aspx",
data: postData,
contentType: "application/json; charset=utf-8",
dataType: "jsonp",
jsonp: 'jsoncallback',
success: callbackfunction,
error: function (msg) { alert(msg); }
});
}
Asp.net page:
protected void Page_Load(object sender, EventArgs e)
{
string userName = "";
int userId = -1;
string PassWord = "";
if (Request.QueryString.Count != 0 && Request.QueryString["username"] != string.Empty && Request.QueryString["password"] != string.Empty)
{
userName = Request.QueryString["username"];
PassWord = Request.QueryString["password"];
userId = GetUserID(userName, PassWord);
}
}
Do you have any ideas why isn't the data passed correctly ? Or do you have any other ideas on how can I make a login page using html and access the data at SQL.
Thanks a lot.
