jquery my html value of a div disappears after showing

Hi,

my login procedure looks like this:

$("#btnLogin").click(function() {
var email = $("#email").val();
var pw = $("#pw").val();

$.get("../Admin/loginForum.aspx", { email: email, pw: pw, mem: "mem" },
function(data) {
$("#LogResponse").html(data.message);
$("#LogResponse").show();
if (data.success) {
$("#LogResponse").after('<span class="error">bla bla bla</span>');
}
}, 'json');
});

the html is:

<table id="tblLoginForum" class="News" width="100%">
<tr>
<td colspan="2"><b>Login Forum</b></td>
</tr>
<tr>
<td>
user name (Email)</td>
<td>
<asp:TextBox ID="email" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
password</td>
<td>
<asp:TextBox ID="pw" runat="server" TextMode="Password"></asp:TextBox>
</td>
</tr>
<tr>
<td>
 </td>
<td>
<asp:Button ID="btnLogin" runat="server" Text="login" Font-Bold="True" />
</td>
</tr>
<tr>
<td colspan="2" >
<div id="LogResponse"></div></td>
</tr>....

after the login is pressed and the $get returns with success,
the return data is placed in the right place and the messege below as well,
but if seems that the page is being refreashed after a few seconds and everything disappears

Can anybody tells me why? and what should I do to avoid it?

thanks

try adding event.preventDefault(); in the click event:

        $("#btnLogin").click(function(event) {
            event.preventDefault();
            var email = $("#email").val();
            var pw = $("#pw").val();
         
            $.get("../Admin/loginForum.aspx", { email: email, pw: pw, mem: "mem" },
                    function(data) {
                        $("#LogResponse").html(data.message);
                        $("#LogResponse").show();
                        if (data.success) {
                            $("#LogResponse").after('<span class="error">bla bla bla</span>');
                        }        
                    }, 'json');
        });

Open in new window

You also need to add event as a parameter in the click function as above
