在上篇文章给大家介绍了使用openSpeDiv方法实现Ecshop登录弹窗框效果,大家点击参考下

下面介绍如何实现AJAX弹窗登录。

在ECSHOP中的user.PHP中有处理用户登录的请求。

/* 处理 ajax 的登录请求 */ 
elseif ($action == 'signin') 
{ 
 include_once('includes/cls_json.php'); 
 $json = new JSON; 
 $username = !empty($_POST['username']) ? json_str_iconv(trim($_POST['username'])) : ''; 
 $password = !empty($_POST['password']) ? trim($_POST['password']) : ''; 
 $captcha = !empty($_POST['captcha']) ? json_str_iconv(trim($_POST['captcha'])) : ''; 
 $result = array('error' => 0, 'content' => ''); 
 $captcha = intval($_CFG['captcha']); 
 if (($captcha & CAPTCHA_LOGIN) && (!($captcha & CAPTCHA_LOGIN_FAIL) || (($captcha & CAPTCHA_LOGIN_FAIL) && $_SESSION['login_fail'] > 2)) && gd_version() > 0) 
 { 
  if (empty($captcha)) 
  { 
   $result['error'] = 1; 
   $result['content'] = $_LANG['invalid_captcha']; 
   die($json->encode($result)); 
  } 
  /* 检查验证码 */ 
  include_once('includes/cls_captcha.php'); 
  $validator = new captcha(); 
  $validator->session_word = 'captcha_login'; 
  if (!$validator->check_word($_POST['captcha'])) 
  { 
   $result['error'] = 1; 
   $result['content'] = $_LANG['invalid_captcha']; 
   die($json->encode($result)); 
  } 
 } 
 if ($user->login($username, $password)) 
 { 
  update_user_info(); //更新用户信息 
  recalculate_price(); // 重新计算购物车中的商品价格 
  $smarty->assign('user_info', get_user_info()); 
  $ucdata = empty($user->ucdata)? "" : $user->ucdata; 
  $result['ucdata'] = $ucdata; 
  $result['content'] = $smarty->fetch('library/member_info.lbi'); 
 } 
 else 
 { 
  $_SESSION['login_fail']++; 
  if ($_SESSION['login_fail'] > 2) 
  { 
   $smarty->assign('enabled_captcha', 1); 
   $result['html'] = $smarty->fetch('library/member_info.lbi'); 
  } 
  $result['error'] = 1; 
  $result['content'] = $_LANG['login_failure']; 
 } 
 die($json->encode($result)); 
} 

把上面这段代码修改一下,删掉需要验证码的部分

改成

/* 处理 ajax弹窗登录请求 */ 
elseif ($action == 'ajax_login') 
{ 
 include_once('includes/cls_json.php'); 
 $json = new JSON; 
 $username = !empty($_POST['username']) ? json_str_iconv(trim($_POST['username'])) : ''; 
 $password = !empty($_POST['password']) ? trim($_POST['password']) : ''; 
 $result = array('error' => 0, 'content' => ''); 
 $captcha = intval($_CFG['captcha']); 
 if ($user->login($username, $password)) 
 { 
  update_user_info(); //更新用户信息 
  recalculate_price(); // 重新计算购物车中的商品价格 
  $smarty->assign('user_info', get_user_info()); 
  $ucdata = empty($user->ucdata)? "" : $user->ucdata; 
  $result['ucdata'] = $ucdata; 
  $result['content'] = $smarty->fetch('library/member_info.lbi'); 
 } 
 else 
 { 
  $result['error'] = 1; 
  $result['content'] = $_LANG['login_failure']; 
 } 
 die($json->encode($result)); 
} 

// 不需要登录的操作或自己验证是否登录(如ajax处理)的act 
$not_login_arr = 
array('login','act_login','register','act_register','act_edit_password','get_password','send_pwd_email','password', 'signin', 'add_tag', 'collect', 'return_to_cart', 'logout', 'email_list', 'validate_email', 'send_hash_mail', 'order_query', 'is_registered', 'check_email','clear_history','qpassword_name', 'get_passwd_question', 'check_answer'); 

改成

// 不需要登录的操作或自己验证是否登录(如ajax处理)的act 
$not_login_arr = 
array('ajax_login','login','act_login','register','act_register','act_edit_password','get_password','send_pwd_email','password', 'signin', 'add_tag', 'collect', 'return_to_cart', 'logout', 'email_list', 'validate_email', 'send_hash_mail', 'order_query', 'is_registered', 'check_email','clear_history','qpassword_name', 'get_passwd_question', 'check_answer'); 

common.js文件下,

在openLginDiv()方法里,将newDiv.innerHTML的HTML代码修改下,在登录框标签里加个ajaxLoginSubmit()方法。

//生成层内内容 
 newDiv.innerHTML = '<form id="ajax_loginForm">用户名:<br><input type="text" name="username" id="ajax_username"/>密码:<br><input type="password" name="password" id="ajax_password"/><br><br><button type="button" onclick="ajaxLoginSubmit()">登录</button> <button type="button" onclick="closeLoginForm()">关闭</button></form>'; 

再自己写两个方法即可

function ajaxLoginSubmit(){ 
 var username = document.getElementById('ajax_username').value; 
 var password = document.getElementById('ajax_password').value; 
 Ajax.call('user.php?act=ajax_login','username='+username+'&password='+password,ajaxLoginResponse,'POST','JSON'); 
} 
function ajaxLoginResponse(result){ 
 if(result.error == 0){ 
  alert('登录成功'); 
 }else{ 
  alert('登录失败'); 
 } 
 return false; 
}
