Disable autocomplete via CSS

问题:

Is it possible to use CSS to disable autocomplete on a form element (specifically a textfield)?

I use a tag library which does not permit the autocomplete element and I would like to disable autocomplete without using Javascript.

回答1:

You can use a generated id and name everytime, which is different, so the browser cannot remember this text-field and will fail to suggest some values.

This is at least the cross browser safe alternative, but I would recommend to go with the answer from RobertsonM (autocomplete="off").

回答2:

As it stands, there is no 'autocomplete off' attribute in CSS. However, html has an easy code for this:

<input type="text" id="foo" value="bar" autocomplete="off" />

If you're looking for a site-wide effector, an easy one would be to simply have a js function to run through all 'input' s and add this tag, or look for the corresponding css class / id.

The autocomplete attribute works fine in Chrome and Firefox (!), but see also Is there a W3C valid way to disable autocomplete in a HTML form?

回答3:

you can easily implement by jQuery

$('input').attr('autocomplete','off');

回答4:

If you're using a form you can disable all the autocompletes with,

<form id="Form1" runat="server" autocomplete="off">

回答5:

CSS does not have this ability. You would need to use client-side scripting.

回答6:

I tried all suggested ways from this question answers and other articles in the web but not working anyway. I tried autocomplete="new-random-value", autocomplete="off" in form element, using client-side script as below but outside of $(document).ready() as one of the user mentioned:

$(':input').on('focus', function () {
  $(this).attr('autocomplete', 'off')
});

I found maybe another priority in the browser cause this weird behavior! So I searched more and finally, I read again carefully below lines from this good article:

For this reason, many modern browsers do not support autocomplete="off" for login fields:

If a site sets autocomplete="off" for a , and the form includes username and password input fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page. If a site sets autocomplete="off" for username and password fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page. This is the behavior in Firefox (since version 38), Google Chrome (since 34), and Internet Explorer (since version 11).

If you are defining a user management page where a user can specify a new password for another person, and therefore you want to prevent auto-filling of password fields, you can use autocomplete="new-password"; however, support for this value has not been implemented on Firefox.

It's just worked. I tried in chrome specially and I hope this continues working and help others.

Thanks to @ahhmarr's solution I was able to solve the same problem in my Angular+ui-router environment, which I'll share here for whoever's interested.

In my index.html I've added the following script:

<script type="text/javascript">
    setTimeout(function() {
        $('input').attr('autocomplete', 'off');
    }, 2000);
</script>

Then to cover state changes, I've added the following in my root controller:

$rootScope.$on('$stateChangeStart', function() {
                $timeout(function () {
                    $('input').attr('autocomplete', 'off');
                }, 2000);
            });

The timeouts are for the html to render before applying the jquery.

If you find a better solution please let me know.

I solved the problem by adding an fake autocomplete name for all inputs.

$("input").attr("autocomplete", "fake-name-disable-autofill");

回答9:

$('input').attr('autocomplete','off');
