How to disable autocomplete and suggestions for corrections in HTML fields?

Autocomplete presents some difficulties, Mozilla says .

They suggest the following ways, you can try one by one, since depending on the type of browser you use and if your forms ask for password type data, one or the other will work:

 1. autocomplete="off"
 2. autocomplete="nope"           //una cadena aleatoria cualquiera
 3. autocomplete="new-password"   //formularios que piden password

Now I explain, according to Mozilla, why possibilities 2 and 3.

In some cases, the browser will keep suggesting autocompletion values ​​even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really forcing the no-autocompletion is to assign a random string to the attribute:

In some cases, the browser will still suggest autocomplete values ​​even if the autocomplete attribute is disabled. This unexpected behavior can be very disconcerting for developers. The trick to force not to use autocomplete is to assign a random string to the attribute , for example:

 autocomplete="nope"

The autocomplete attribute and login fields

Modern browsers implement integrated password management: when the user enters a username and password for a site, the browser offers to remember it for the user. When the user visits the site again, the browser autofills the login fields with the stored values.

Additionally, the browser enables the user to choose a master password that the browser will use to encrypt stored login details.

Even without a master password, in-browser password management is generally seen as a net gain for security. Since users do not have to remember passwords that the browser stores for them, they are able to choose stronger passwords than they would otherwise.

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

If a site sets autocomplete="off" for a form, 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 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. This is the behavior in Firefox (since version 38), Google Chrome (since 34), and Internet Explorer (since version 11).

If an author would like to prevent the autofilling of password fields in user management pages where a user can specify a new password for someone other than themself, autocomplete="new-password" should be specified, though support for this has not been implemented in all browsers yet.

Modern browsers implement integrated password management: when the user enters a username and password for a site, the browser offers to remember it for the user . When the user visits the site again, the browser automatically fills in the login fields with the stored values.

Even without a master password, in-browser password management is often seen as a net gain for security. Since users don't have to remember the passwords that the browser stores for them, they can choose stronger passwords than they otherwise would.

For this reason, many modern browsers don't support autocomplete= "off" for login fields :

If a site sets autocomplete="off" for a form, and the form includes username and password input fields, the browser will still offer to remember this login and if the user accepts, the browser will automatically fill them in next time that the user visits the page.

If an author wants to prevent autofilling of password fields on user management pages where a user can specify a new password for someone other than themselves, autocomplete = "new-password" should be specified, although support for this has not been implemented in all browsers yet .

What it essentially says is that, in some browsers, in forms that have password fields, autocomplete will ignore it even if it's off and will continue to suggest data... to turn it off you have to do something a little weird :)

   autocomplete="new-password"

Try those three possibilities.

EDIT In the specific case of this question, it has worked for the OP to add the following attribute to the input in question:

    <input .... spellcheck="false"> ... </input>

I found the solution by adding the attribute spellcheck="false" , and it turned out like this:

<input type="text" [(ngModel)]="place2search" autocomplete="off" spellcheck="false">

Thanks for the suggestions..

You only need the "autocomplete" with the off attribute, it's strange that it doesn't work for you...

Note works in HTML5.

But well here you have an official example (in English) of the w3 I hope it will help you.

Try the attribute autocomplete="off"(I think it only works in HTML5 ).

<input type="text" [(ngModel)]="place2search" autocomplete="off" />
