当我在客户端散列我的密码时，我没有得到散列字符串而是得到密码本身

Question

我试图在将密码发送到我的服务器（Tomcat 服务器）之前在客户端散列我的密码，当我单击提交时，在将密码值更新为哈希码我如何确保我的表单在脚本执行后得到提交？或者有更好的方法吗？

<html>
<head>
    <title>TODO supply a title</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, 
initial-scale=1.0">
</head>
<body>
    <h1></h1>
    <form method="post" onsubmit="encrypt(event);" action="login" >
        <input type="text" name="user_id">
        <input type="password" name="password" id="pass">
        <button id="but1" type="submit">submit</button>
    </form>
    <script>
function encrypt(event){
//  event.preventDefault();//prevents from form getting auto submitted              
document.querySelector("body").style.color="red";             
sha512(document.getElementById("pass").value).then((x)=> 
{                
document.getElementById("pass").value=x;                   
document.querySelector("h1").innerHTML = x;
});
}


            function sha512(str) {
            return crypto.subtle.digest("SHA-512", new TextEncoder("utf- 
8").encode(str)).then(buf => {
            return Array.prototype.map.call(new Uint8Array(buf), x=> 
(('00'+x.toString(16)).slice(-2))).join('');
            });
            }
            sha512("my string for hashing").then(x => console.log(x)); 
    </script>
  </body>
</html>

完成流程后提交您的表格

 <form id="form1" method="post" onsubmit="encrypt(event);" action="login" >
        <input type="text" name="user_id">
        <input type="password" name="password" id="pass">
        <button id="but1" type="submit">submit</button>
    </form>


function encrypt(event) {
  event.preventDefault(); //prevents from form getting auto submitted
  document.querySelector("body").style.color = "red";
  sha512(document.getElementById("pass").value).then((x) => {
    document.getElementById("pass").value = x;
    document.querySelector("h1").innerHTML = x;
    document.getElementById("form1").submit(); // submitting the form
  });
}

当我在客户端散列我的密码时，我没有得到散列字符串而是得到密码本身

when I hash my password on the client side , I am not getting the hashed string instead getting the password itself

html

javascript

hash

tomcat
