使用 ajax 获取表单以获取 php 响应时遇到问题。javascript 似乎是正确的,因为如果我删除 login_ajax.php 上的所有内容并且只使用以下内容,它就可以工作
echo 'CORRECT' 
//or 
echo 'INCORRECT'
一旦我使用了真正的 php 代码,ajax 就不会得到 PHP 的任何响应。更奇怪的是,如果我删除
return false
从 javascript 然后提交表单,我确实看到浏览器的 login_ajax.php 上显示了正确或错误。
HTML:
<form id="login" action='login_ajax.php' method="get">
    <label>Email: <input type="text" name="email" id="email" value="nano@nano.com"></label>
    <label>Password: <input type="text" name="password" id="password" value="x"></label>
    <input type="submit" value="login">
    <div id="straight_response">php response here</div>
    <div id="message">status</div>
</form>
PHP:
if (isset($_GET['password'])) {
    $email = $_GET['email'];
    $password = $_GET['password'];
    $stored_pass = "123";
    if ($password == $stored_pass) {
        echo "CORRECT";
    } else {
        echo "INCORRECT";
    }
}
//Javascript works when using one of the two lines below instead of the code above
//echo 'INCORRECT';
//echo 'CORRECT'
JAVASCRIPT:
$('#login').submit(function(){
var email;
    var password;
    email       = $('#email').val();
    password    = $('#password').val();
    var data = {};
    data.email  = email;
    data.password   = password;
    var options = {};
    options.dataType = 'text';
    options.type = 'get';
    options.url= 'login_ajax.php';
    options.success = function (response) {
    //  jQuery.trim(response);
        console.log(response.results);
        console.log(response.query);
        $('#always').text(response);
        if (response === 'CORRECT') {
            $('#message').text('you got it right');
            console.log("good combination");
        }
        else if (response === 'INCORRECT') {
            $('#message').text('sorry, try again');
            console.log("bad combination");
        }
    };
    $.ajax(options);
    return false;
});//#login function
