Question

这应该是一个基本问题，但我正在学习。我正在登录系统，用户输入用户名和密码。如何通过javascript将密码发送到我的函数哈希。因为我需要将它与我的数据库中的那个进行比较。如果密码hashed =数据库密码，那就没问题。

<div align="center"> 
     <form action="connection.php" method="post">    
          <p>Fill your crendentials</p>
          <label for="usrUserName">Your login</label> 
          <input id="usrUserName" name="usrUserName" /><br />    
          <tr><td>Password</td><td><input type="password" name="usrPassword" maxlength="25" id="usrPassword"/>    
          <form action="insert.php" method="post" onsumbit="return create_hash()">
     </form>
</div>

这就是我现在所拥有的。我可以向你展示函数哈希，但人们说这不是一个好主意。

        <script type="text/javascript">
define("PBKDF2_HASH_ALGORITHM", "sha1");
define("PBKDF2_ITERATIONS", 1000);
define("PBKDF2_SALT_BYTES", 24);
define("PBKDF2_HASH_BYTES", 24);

define("HASH_SECTIONS", 4);
define("HASH_ALGORITHM_INDEX", 0);
define("HASH_ITERATION_INDEX", 1);
define("HASH_SALT_INDEX", 2);
define("HASH_PBKDF2_INDEX", 3);

function create_hash($usrPassword)
{


var usrPassword =document.getElementById("usrPassword").value;

   // format: algorithm:iterations:salt:hash
   $salt = base64_encode(mcrypt_create_iv(PBKDF2_SALT_BYTES, MCRYPT_DEV_URANDOM));
   return PBKDF2_HASH_ALGORITHM . ":" . PBKDF2_ITERATIONS . ":" .  $salt . ":" .
       base64_encode(pbkdf2(
           PBKDF2_HASH_ALGORITHM,
           $usrPassword,
           base64_decode($salt),
           PBKDF2_ITERATIONS,
           PBKDF2_HASH_BYTES,
           true

       )); 
       alert("usrPassword");
}

function validate_password($usrPassword, $good_hash)
{
   $params = explode(":", $good_hash);
   if(count($params) < HASH_SECTIONS)
      return false;
   $pbkdf2 = base64_decode($params[HASH_PBKDF2_INDEX]);
   return slow_equals(
       $pbkdf2,
       pbkdf2(
           $params[HASH_ALGORITHM_INDEX],
           $usrPassword,
           base64_decode($params[HASH_SALT_INDEX]),
           (int)$params[HASH_ITERATION_INDEX],
           strlen($pbkdf2),
           true
       )
   );

Answer 1

这是您的HTML代码： -

<form action = 'connection.php' method="post"  >

<p> Entrer vos informations  </p>

 <label for="usrUserName">Votre code d'usager </label> 
<input id="usrUserName" name="usrUserName" /><br />

   <tr><td>Password</td><td>
<input type="password" name="usrPassword" maxlength="25" id="usrPassword"/>
</td>

<form  action="insert.php" method="post" onsumbit="return create_hash()">
</form>

当你打电话时

<script type="text/javascript">

function create_hash(){

var pass =document.getElementById("usrPassword").value;

alert(pass);//here is your password
return false//for stop function
}

</script>

Answer 2

您应该将值传递为字符串：

<input type="button" name="myValue" value="Remove" onclick="del('<?echo $myArray[0]?>');"/>

您还可以使用json_encode（）将值转换为值JavaScript：

将PHP变量从输入字段传递给JavaScript函数
