使用 jQuery 在句子中用 XXXX 替换数字和电子邮件

Question

我想替换句子中的数字和电子邮件。

示例

$message = "嗨，我是 john，我的个人电话号码是 1213456789，我的电子邮件地址是 john@gmail.com"。

输出：

您好，我是 john，我的个人电话号码是 1213456789，我的电子邮件地址是 john@gmail.com

我希望输出是这样的：

输出：

您好，我是 john，我的个人编号是 XXXXXXX789，我的电子邮件地址是 XXXX@gmail.com

但我现在是这样的：

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX@gmail.com

我现在使用的函数

function numbers1($str)
{
 if(($until = strpos($str, '@')) !== false)
 {
  $str = str_repeat('X', $until) . substr($str, $until);
 }
}

提前致谢。

Answer 1

$message = "Hi this is john, my personal no is 1213456789 and my email address is john@gmail.com";
$arr = explode(" ", $message);
foreach($arr as $key=>$val)
{   
    if(!preg_match ("/[^0-9]/", $val))
    {
        $val_new = "XXXXXXX".substr($val, -3);
        $arr[$key] = $val_new;
    }
    else if(strpos($val, "@")>0)
    {   
        $arr_email = explode("@", $val);
        $arr_email[0] = "XXXX";
        $val_new = implode("@", $arr_email);
        $arr[$key] = $val_new;
    }
}

$new_msg = implode(" ", $arr);
echo $new_msg;

更新 2：

$message = "Hi this is john, my personal no is 1213456789 and my email address is john@gmail.com";
    $arr = explode(" ", $message);
    foreach($arr as $key=>$val)
    {   
        if(!preg_match ("/[^0-9]/", $val))
        {
            $val_new = "XXXXXXX".substr($val, -3);
            $arr[$key] = $val_new;
        }
        else if(preg_match ("/^[a-z0-9_\+-]+(\.[a-z0-9_\+-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*\.([a-z]{2,4})$/", $val))
        {   
            $arr_email = explode("@", $val);
            $arr_email[0] = "XXXX";
            $val_new = implode("@", $arr_email);
            $arr[$key] = $val_new;
        }
    }

    $new_msg = implode(" ", $arr);
    echo $new_msg;

Answer 2

您正在询问如何使用 jQuery 来执行此操作，但是您的示例代码是用 PHP 编写的。我也会用 PHP sn-p 回答你的问题。

您的函数不起作用的原因是因为您要替换从字符串开头到找到第一个'@'的位置的几乎所有内容。然后，您将添加与字符一样多的“X”，直到该位置，然后是字符串的其余部分。更复杂的是，如果在您的字符串中找到两个或多个电子邮件地址，这将不起作用。

这应该可以。不过，您可能需要调整电话号码和电子邮件地址的正则表达式：

$message = "Hi this is john, my personal no is 1213456789 and my email address is john@gmail.com";

// get all phone numbers
preg_match('/\d{3,}/s', $message, $phones);
// get all email addresses
preg_match('/[a-z.-]+@[a-z.-]+/s', $message, $emails);

foreach ($phones as $phone)
{
    $message = str_replace($phone, str_repeat('X', strlen($phone) - 3) . substr($phone, -3), $message);
}

foreach ($emails as $email)
{
    $parts = explode('@', $email);
    $message = str_replace($email, str_repeat('X', strlen($parts[0])) . '@' . $parts[1], $message);
}

// Hi this is john, my personal no is XXXXXXX789 and my email address is XXXX@gmail.com
echo $message;

试试preg_replace()

$str = "Hi this is john, my personal no is 1213456789 and my email address is john@gmail.com";
$replacements[1] = 'X';
$replacements[0] = 'XXXX@';
echo preg_replace(array('/[0-6]/', '/[ a-z]{0,4}+@/'), $replacements, $str);

输出：- Hi this is john, my personal no is XXXXXXX789 and my email address is XXXX@gmail.com
