$(function() {        $("a[name='logout']").live('click',function() {  // Now using the .live() event        $.post("logout.php", function(data) { $("li.login").html(data); bind_login_submit();     // <---- Notice, this is new        });    });    bind_login_submit();    // Call this function to initially bind the submit});function bind_login_submit() {    $("form#login").unbind('submit').bind('submit',function() {        var usernameval = $("input[name='username']").val();        var passwordVal = $("input[name='password']").val();        $.post("login.php",{username : usernameval, password : passwordVal}, function(data) { $("li.login").html(data);        });        return false;    });}
