Question

我想创建一个 JavaScript对象，如下所示。

if ($_POST['answer'] == $_POST['answer-hidden']) {
  $user_name = $wpdb->escape($_POST['username']);
  $user_email = $wpdb->escape($_POST['email']);
  $password = $wpdb->escape($_POST['pwd']);
  $confirm_password = $wpdb->escape($_POST['confirm']);
  $user_id = username_exists( $user_name );

  if (!$user_id and email_exists($user_email) == false and !empty($user_email) and !empty($user_name) and is_email($user_email)) {
    $user_id = wp_create_user( $user_name, $password, $user_email );
    $from = get_option('admin_email');
    $headers = 'From: '.$from . "\r\n";
    $subject = "Registration successful";
    $msg = "Registration successful \n Your login details \n Username: $user_name \n Password: $password \n $login";
    $headers2 = 'From: '.$user_email . "\r\n";
    $subject2 = "New user register on your website.";
    $msg2 = "New user register on your website \n User details are \n Username: $user_name \n Email: $user_email";
    wp_mail( $user_email, $subject, $msg,  $headers);
    wp_mail( $from, $subject2, $msg2,  $headers2);
    $login_data = array();
    $login_data['user_login'] = $user_name;
    $login_data['user_password'] = $password;
    $user_verify = wp_signon( $login_data, false );

    // wp_signon is a wordpress function which authenticates a user. It accepts user info parameters as an array.
    if (isset($_POST['op-register'])) {
      if ($_POST['submit'] == 'Register') {
        if (is_wp_error($user_verify)) {
            $UserError = __('Invalid username or password. Please try again!','agrg');  
        } else {
            echo $profile;
            global $redux_demo;
            $profile = $redux_demo['profile'];
            wp_redirect( $profile );

        }
      }
    }
  }
}

为此，我开发的js函数如下。

var codropsEvents = {
    '02-02-2017' : '<span>Some txt from database</span><span>Some txt from database</span>',
    '02-05-2017' : '<span>Some txt from database</span><span>Some txt from database</span>'
};

calendarData.php 文件生成以下字符串（包括所有冒号，逗号，标签等）

function setEventsCalendar() {
    var codropsEvents
    try {
        $.ajax({
            type: "POST",
            url: "calendarData.php",
            dataType: "text",
            async: false,
            success: function(msg) {
                codropsEvents = "{" + msg + "}";
                codropsEvents = JSON.parse(codropsEvents);
            }
        });

        return codropsEvents;
    } catch(ex) {
        alert(ex);
    }
}

var codropsEvents = setEventsCalendar();

如何使用该String创建JS对象？或任何其他适当的方式来获得预期的结果。

你可以在php-

中创建一个数组

$dataArray = ['02-02-2017' => '<span>Some txt from database</span><span>Some txt from database</span>',
              '02-05-2017' => '<span>Some txt from database</span><span>Some txt from database</span>'];
// and this array to json string and print it,
 echo json_encode($dataArray,JSON_FORCE_OBJECT);

现在在ajax部分，您可以通过将dataType更改为json来简单地获取json格式的数据;成功函数的msg参数是javascript对象，或者在成功函数中有codropsEvents = JSON.parse(msg);之类的代码。

如何使用数据库中的数据创建JavaScript对象？
