Basically Im following the tutorial from:
how to call an ASP.NET c# method using javascript
this code will create a userform and prompt the user to enter name and password.
I created a webform called Default.aspx
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
</asp:ScriptManager>
<fieldset style="width: 200px;">
<asp:Label ID="lblEmailAddress" runat="server" Text="Email Address"></asp:Label>
<asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>
<asp:Label ID="lblPassword" runat="server" Text="Password"></asp:Label>
<asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
</fieldset>
<div>
</div>
<asp:Button ID="btnCreateAccount" runat="server" Text="Signup" OnClientClick="Signup();return false;" />
</div>
</form>
</body>
</html>
<script type="text/javascript">
function Signup() {
var email = document.getElementById('<%=txtEmail.ClientID %>').value;
var password = document.getElementById('<%=txtPassword.ClientID %>').value;
PageMethods.RegisterUser(email, password, onSucess, onError);
function onSucess(result) {
alert(result);
}
function onError(result) {
alert('Cannot process your request at the moment, please try later.');
}
}
</script>
and under Default.aspx.cs I have
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace email1
{
public partial class _Default : Page
{
[WebMethod]
public static string RegisterUser(string email, string password)
{
string result = "Congratulations!!! your account has been created.";
if (email.Length == 0)//Zero length check
{
result = "Email Address cannot be blank";
}
else if (!email.Contains(".") || !email.Contains("@")) //some other basic checks
{
result = "Not a valid email address";
}
else if (!email.Contains(".") || !email.Contains("@")) //some other basic checks
{
result = "Not a valid email address";
}
else if (password.Length == 0)
{
result = "Password cannot be blank";
}
else if (password.Length < 5)
{
result = "Password canonot be less than 5 chars";
}
return result;
}
}
}
}
