我正在嘗試重新設計一個登錄頁面，以便在一個頁面中包含登錄/註冊表單，而不是具有2個單獨的頁面。以前我有我的登錄和註冊頁面都通過php正確訪問我的數據庫。
我試圖簡單地複製我以前爲每個人工作但需要下面的教程頁面所需的元素，但是我的數據庫連接/ php似乎沒有做任何事情。爲登錄/註冊模式實現正確的php數據庫訪問
我在下面http://codyhouse.co/gem/loginsignup-modal-window/

老validation2.js（相當於什麼main.js上面一樣）參考
$(window).load(function() {
$('#submitBtn').click(function() {
return validate();
});
//Assign two functions for acting displaying message and removing it
function displayMsg(msg) {
$('.msg').html(msg);
}
function clearMsg() {
$('.msg').html("");
}
function validate() {
var loginUsername = $('#log_username');
var loginPass = $('#log_password');
//the rule of validating letters and email format
// var emailRegex = /^\[email protected][a-zA-Z_]+?\.[a-zA-Z]{2,3}$/;
//Login validation:Email
//if (emailRegex.test(loginEmail.val())) {
if (loginUsername.val() != 0){
loginUsername.removeClass("erroB");
} else {
loginUsername.addClass("erroB");
displayMsg("Please check your username");
return false;
}
//Login validation:Password
if (loginPass.val() != 0) {
loginPass.removeClass("erroB");
} else {
loginPass.addClass("erroB");
displayMsg("Password is required");
return false;
}
clearMsg();
return true;
}
//make the validation be immidiatelly.
$('input').keyup(function() {
validate();
});
});
我只用越來越合作，啓動登錄部（未登記）嘗試，但即使這沒有做任何事情。
我已經基本上覆制了我從以前的登錄，但無法解決它爲什麼不工作！所有的數據庫憑證都是正確的。
我在這裏錯過了一些非常簡單的東西嗎？
