AngularJS Chrome自动完成难题

我有一个简单的登录表单，除非您使用Chrome的自动完成功能，否则该表单仅适用于桃花心木。

如果您开始输入并使用自动完成功能，并且该功能会自动填充您的密码，则我的angularjs模型的密码没有任何值。

我试图通过在表单上设置属性来关闭自动填充功能，autocomplete="off"但这似乎没有任何效果。

我该怎么做：1.如果有人使用Chrome的自动完成功能，请确保我能获得价值？2.禁用Chrome的自动完成功能？

<form class="form-signin" name="form" ng-submit="login()" autocomplete="off">

        <h3>Login</h3>

        <input type="email" name="email" class="form-control" placeholder="Email address" ng-model="user.email" required autofocus>
        <input type="password" name="password" class="form-control" placeholder="Password" ng-model="user.password" required>

        <button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>

 </form>

// Could break future Angular releases (if use `compile()` instead of `link())
