变更邮寄表格 [英] Change post form

问题描述

我的网站上有简单的登录表格.在给定的要求下，该密码一定不能发送到服务器，而只能发送到MD5哈希.我使用了简单的MD5功能，现在，当使用onClick on Submit按钮时，我将隐藏文本从密码更改为md5(password).这可以正常工作，但用户看到使用密码的事情正在发生.我想使其透明，并使用onPost(或类似的方法)回调动态更改表单的这一特定部分.

I have simple login form in my website. In given requirements stands, that password mustn't been sent to server, but only MD5 hash. I took simple MD5 function and now, when with onClick on submit button I change hidden text from password to md5(password). This works fine, but user sees, that something with his password is happening. I would like to make it transparent and change this particular part of form dynamically with onPost (or smth like this) callback.

我找不到任何教程来处理javascript中的POST表/表单(jquery?)，因此，如果有人可以帮忙，我将不胜感激.

I can't find any tutorials how to deal with manipulating POST table/form in javascript (jquery?) so if anyone could help I would appreciate.

推荐答案

据我所知，没有name的输入字段不会提交到服务器.因此，您可以拥有一个隐藏字段，并在表单的onsubmit事件中通过应用MD5校验和将密码字段的值复制到该隐藏字段中:

As far as I know input fields that don't have name don't get submitted to the server. So you could have a hidden field and in the onsubmit event of the form copy the value of the password field into the hidden field by applying the MD5 checksum:

<form method="post" action="/login">
    <input type="password" id="password" />
    <input type="hidden" name="password" id="hiddenpassword" />
    <input type="submit" value="Login" />
</form>

然后:

$('form').submit(function() {
    var password = $('#password').val();
    var md5 = MD5(password);
    $('#hiddenpassword').val(md5);
    return true;
});
