Form autocomplete attribute

HTML DOM Form Object

Definition and Usage

autocomplete Sets or returns the value of the autocomplete attribute in the form.

After enabling autocomplete, the browser will automatically complete values based on the user's previous input.

Tip: You can set the form to "enable" autocomplete, and set the specific input field to "disable", and vice versa.

Tip: In some browsers, you may need to enable the autocomplete feature to make it work properly (check the "Preferences" menu in the browser menu).
