删除MVC中的浏览器自动完成功能

Question

I am currently trying to remove the form autocompletion done by the user's browser which can cause some critical behavior since it fills the password field. I have already added the autocompletion attribute to all of my textbox fields but when I try with firefox it stills load my current login information into the fields.

Does anyone know how to resolve this issue?

EDIT: Since it's not clear, I have already added the aucompletion attribute with the value set to "off".

Answer 1

There is an autocomplete=off property in html.

It is used in the top right search box on this very page, inspect the html you'll see:

<input autocomplete=​"off" name=​"q" class=​"textbox" placeholder=​"search" ..... />

See this MDN article: https://developer.mozilla.org/en/How_to_Turn_Off_Form_Autocompletion

In MVC you would implement this at the form or for a textbox like so:

Html.BeginForm(
    action, controller, FormMethod.Post, new {autocomplete="off"})

OR

Html.TextBoxFor(model => model.EmployerNumber, new {autocomplete="off"})

Answer 2

如果你在这里检查，在表单上设置autocomplete="off"就可以了。

Answer 3

You can randomize id and name attributes of your textboxes - this will make browser autocomplete functions not working.

My implementation

In view:

<%
    var guidString = Guid.NewGuid().ToString();
%>
<%=Html.TextBox(guidString, String.Empty)%>
<%=Html.Hidden("NameGuid", guidString) %>

in Controller:

string userName = Request[model.NameGuid];
...

The HTML5 have a add-on syntax for form/input elements, it is called autocomplete="off". See http://www.w3schools.com/html5/att_form_autocomplete.asp
