Django PasswordChangeForm中的自动对焦字段是什么？

Question

我正在浏览Django文档，发现这行代码我没有，特别是自动对焦部分

class PasswordChangeForm(SetPasswordForm):
"""
A form that lets a user change their password by entering their old
password.
"""
error_messages = {
    **SetPasswordForm.error_messages,
    'password_incorrect': _("Your old password was entered incorrectly. Please enter it again."),
}
old_password = forms.CharField(
    label=_("Old password"),
    strip=False,
    widget=forms.PasswordInput(attrs={'autocomplete': 'current-password', 'autofocus': True}),
)

field_order = ['old_password', 'new_password1', 'new_password2']

def clean_old_password(self):
    """
    Validate that the old_password field is correct.
    """
    old_password = self.cleaned_data["old_password"]
    if not self.user.check_password(old_password):
        raise ValidationError(
            self.error_messages['password_incorrect'],
            code='password_incorrect',
        )
    return old_password

在widget=forms.PasswordInput（attrs={'autocomplete'：'current password'，'autofocus'：True}）部分中，我不知道autofocus字段是什么，也不知道它在表示为True时做了什么

这样做的目的是什么

Answer 1

autofocus:True使“旧密码”输入字段在页面加载时自动获得焦点。就这么简单
