Need Help - Disable Form Autofill In Chrome

[Surjadeep Banerjee]

Hello Team,

I would like to disable form autofill in chrome (version : 54.0.2840.99 m) from JavaScript. I have tried all possible solutions out there but none of them works for me.

Need help.

Beside constantly changing the name/id/label of the field, I do not think there is a way. It is usually user-hostile.

Hi Surjadeep,

You can suppress autofill of address fields (i.e., fields which are not credit card or login/password related) on desktop platforms using the autocomplete="off" attribute at the form or field level. This method of suppression does not apply to mobile platforms.

What exactly is your scenario/context?

Regards,

Roger

Hello Roger,

Thanks for the reply.

I have actually one issue regarding the autofill in credit card info that changes the order quantity after users allowing cc autofill to save in.

I need to know besides the standard way to block the chrome autofill option, is there any way we can do in via javascript ?

What does it change to? Perhaps the CVV number or the expiration date?

If so and you already have fields for that, you can use autocomplete=cc-csc for the CVV number and autocomplete=cc-exp for the expiration date.

Otherwise, query the various autocomplete values here and pick one that suits the most -

Hi Surjadeep,

It sounds like autofill is mis-classifying your quantity field. If you're able to share (feel free to email me privately), the details of the form in question would be helpful for diagnosis (i.e., field names, ids and types as well as the user-visible label, location and action urls, etc).

Otherwise, PhistucK's suggestions should help, as might renaming the quantity field.

Hello All,

It sounds like discussion a long time ago and now come to priority again the chrome autofill that creates issues by changing the order quantity in shopping cart page.

At first, let me attach two screen shots,

This screen describes the Quantity textbox which is pre-populated in cart page as value 1

Quantity value changes to 05 which is taking from credit card expiry month as soon user try to enter credit card number and the autofill come into action and changes the quantity field value.

Credit Card Number Field:

ID: formattedCardNumber

Name: sialNumberOfCart

Type: Input Text

Quantity Field:

ID: Not given

Name: quantity_1

Type: Input Text

Please let me know if anything I can help.

Thanks,

Surjadeep

You can search crbug.com for an existing issue and star it. If you cannot find one, file a new issue using the "New issue" link on the same page.

Please, do not add a "+1" or "Me too" or "Confirmed" (or similar) comment. It just wastes the time of Chrome engineers and sends unnecessary e-mails to all of the people who starred the issue.

You can reply with a link to the found or created issue and might get triaged (and fixed) faster.

Thank you.
