【问题描述】：

我试图在将密码发送到我的服务器（Tomcat 服务器）之前在客户端对我的密码进行哈希处理，当我点击提交时，表单在将密码的值更新为哈希码之前被提交如何确保我的表单在脚本执行后被提交？或者有更好的方法吗？

【解决方案1】：

完成后提交表单

 <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
  });
}
