当输入类型为密码时，autocomplete ='off' 不起作用，并在其上方设置输入字段以启用自动完成 [英] autocomplete ='off' is not working when the input type is password and make the input field above it to enable autocomplete

问题描述

我有一个禁用了自动完成功能的表单，但它不起作用，并且可以在 Firefox 和更高版本的 chrome 中启用自动完成

I have an form with autocomplete disabled but it does not works and makes the autocomplete to be enabled in firefox and higher version of chrome

<form method="post" autocomplete="off" action="">
    <ul class="field-set">
    <li>
        <label>Username:</label>
        <input type="text" name="acct" id="username" maxlength="100" size="20">
    </li>
    <li>
        <label>Password:</label>
        <input type="password" name="pswd" id="password" maxlength="16" size="20" >
    </li>
    <li>
        <input type="submit" class="button" value="Login" id="Login" name="Login">
    </li>
    </ul>
</form>

当类型从密码更改为文本时，它适用于所有浏览器.谁能帮忙解决这个问题?

When the type is changed from password to text it works in all browser. Can anyone help to solve this issue?

推荐答案

浏览器通常有两个相关但不同的表单功能:

Browser's normally have two related yet different features regarding forms:

• 表单自动完成，其中 <input type="text"> 类型(和类似)的项目收集键入的值并以下拉的形式提供回向下列表.
  (这是一个简单的功能，效果很好.)

• Form auto-complete, where items of <input type="text"> type (and similar) collect typed values and offer them back in the form of a drop-down list.
  (It's a simple feature that works pretty well.)

密码管理器，当浏览器检测到您已提交登录表单时，它会提示您记住用户名/密码组合.返回站点时，大多数浏览器会在下拉框中显示可用的用户名(Firefox、Chrome、Internet Explorer...)，但有些浏览器有工具栏按钮 (Opera).此外，Chrome 以硬编码黄色突出显示字段.
(这取决于启发式方法，可能会在某些页面上失败.)

Password manager, where browser prompts to remember username/password combinations when it detects you've submitted a login form. When returning to the site, most browsers display available usernames in a drop-down box (Firefox, Chrome, Internet Explorer...) but some have a toolbar button (Opera). Also, Chrome highlights the fields in hard-coded yellow.
(This depends on heuristics and might fail on certain pages.)

存在标记为 autocomplete="off" 的表单的边缘情况.如果它是一个登录表单并且用户之前已经存储了用户名/密码，会发生什么?实际上删除本地数据库中的密码看起来不合适，所以可能没有浏览器这样做.(事实上​​，表单自动完成中的数据也不会被删除.)Firefox 决定赋予用户权力:你有密码，所以我会让你使用它.Chrome 决定授权该网站.

There's an edge case with forms tagged as autocomplete="off". What happens if it's a login form and the user has previously stored a username/password? Actually removing the password from the local database looks like inappropriate so probably no browser does so. (In fact, data from form auto-complete is not erased either.) Firefox decides to give power to the user: you have a password, so I'll let you use it. Chrome decides to give power to the site.
