它没有显示!怎么了?有解决方案吗id名称是正确的
编辑: 我有另一个问题。不想为此打开另一个问题。我正在尝试从validate.php获取ajax答案(它位于/views/admin/validate.php - 它在打开domain.com/validate时运行)
$(document).ready(function() {
$('.login-button').click(function() {
var login = $("#login").val();
var password = $('#password').val();
$.ajax({
type: 'POST',
url: '/view/admin/validate.php',
data: {
login : login,
password : password
},
success: function(data){
$('#login-error').html(data);
}
});
});
});
validate.php
<?php
session_start();
$user = mysql_real_escape_string($_POST['login']);
$password = mysql_real_escape_string(sha1($_POST['password']));
$query = mysql_query("SELECT * FROM `users` WHERE name = '$user' AND pass = '$password' AND privileges = 'superuser'");
$num_rows = mysql_num_rows($query);
if($num_rows == '0') {
echo "Username and Password are incorrect! (Maybe you don't have permission!)";
}
elseif($num_rows == '1') {
$expire = time()*60*60*60*60;
setcookie("user","$user",$expire);
$_SESSION['user'] = $user;
include '/views/admin/admin.php';
}
?>
应该返回用户名和密码不正确! (也许你没有许可!) - 但它没有..任何解决方案??

var login = $("#login").val();
当此行运行时,输入为空。
您需要在用户输入内容后获取值。

答案 2 :(得分:0)
试一试:
$('.login-button').click(function() {
alert($("#login").val());
});
或:
$('.login-button').click(function() {
var login = $("#login").val();
alert(login);
});
或:
var login = "";
$('.login-button').click(function() {
login = $("#login").val();
alert(login);
});
